Fuels - Science topic

As a design engineer in an engineering team whose work is developing a new gas turbine of 2 MW used for thermal power generation which is fuelled by non-carbon fuels, such as hydrogen and ammonia, your task is to analyse and design the combustion system for providing stable and efficient combustion in the gas turbine.

Hello Everyone,

Is it possible to use biodiesel fuels in aviation/ aircraft? if yes, what is the percentage volume of biodiesel that is allowed to use in aircraft nowadays? if there is any article approve that please share it with me.

Thanks in Advance,

How can we have power plants that are fueled by factory waste and microorganisms?

In your opinion, should we target Biodiesel, Hybrid Vehicles, Sustainable Aviation Fuel, Electric Vehicles or some combination of these? Do you agree with your country's approach to this problem?

My opinion is that synthetic and bio-based fuels should be quickly adopted to bridge the gap until electric vehicles can dominate. In parallel, the electricity generation and delivery infrastructure needs to be transitioned to lower-emission methods such as wind and nuclear power.

Hello scientific community,

I am working on OBODM and wanted to know if a source that is made up of multiple fuels, eg. 20% Ground Illum. Signal, Red Star, M158 + 60% Propellant, M-9 + 20% Signal, Illum, Aircraft, Rd Str, AN-M43A2 can be inputted into OBODM. If yes, can you please provide me some guidance on how to do so? If not, then would you suggest that the source be user defined with a heat content calculated using the individual fuel fractions? The purpose of using OBODM is to obtain the release height for both OB and OD operations at the facility and therefore, it would be helpful to understand if such in depth detailing of the source composition is even necessary, as it is only a function of heat content, burn rate, wind speed and stability class.

Thank you!

Dear colleagues

I just posted a short Note, mostly addressed to my Linked In platform contacts, followers and interested individuals, that addresses the issue regarding the foreseeable long-term impacts of "Virtual Contact" upon the Cities, their transport infrastructure, and most importantly may be, their Central Business Districts (CBDs).

In it I hint at the set-up of a New Urban Economics Model. The use of nonlinear dynamics and exogenous shocks as fueling a new wave of spatial Schumpeterian gales of destruction is hinted in that short Note.

Also, the worlds of a Cybercity and a Location Theory on Cyberspace are briefly outlined.

I wonder if this community has any thoughts on this subject. Thanks!

The aforementioned Note is found here: (PDF) ON THE LONG-TERM EFFECTS OF "VIRTUAL CONTACT" UPON CITIES, TRANSPORT INFRASTRUCTURE, AND CENTRAL BUSINESS DISTRICTS (CBDs) (researchgate.net)

I am looking for the best model of route optimization to adopt on my research that I can use to assess variables such as costs of different fuels, and the surrounding along those roads.

Thanks in advance for valuable information.

I am looking for low heat values and air-fuel stoichiometric ratios for biofuels--in particular, values for dimethyl ether, mono oxymethylene dimethyl ether (OME1), and for biodiesel. I will check performance of their blends in an engine specifically tailored to operate efficiently with these fuels.

Hello Robert !

In your calculations, there are not enough numbers for ordinary (basic jet fuel), please send them if you have them, so it will be right.

For clarity, I made a picture.

Thanks !

Sincerely, Ivan Antipov.

Going by the recent complain in UK about E10 fuel. Please do share your thoughts.

Thank you

What's the best definition you've seen? I would like to use an existing government policy or national lab/academies report. Or, how could I improve these two draft definitions below?

To start, the US Energy Policy Act of 1992 still seems to be the authority on "alternative fuel." (Thank you EERE for making this list easy to find.)

Methanol, ethanol, and other alcohols

Blends of 85% or more of alcohol with gasoline

Natural gas and liquid fuels domestically produced from natural gas

Liquefied petroleum gas (propane)

Coal-derived liquid fuels

Hydrogen

Electricity

Fuels (other than alcohol) derived from biological materials (including pure biodiesel (B100))

P-Series

My first stabs at "drop-in" and "non-drop-in." (Thank you CAAFI for getting me started.)

Drop-in Alternative Fuel:

An alternative fuel that is completely interchangeable and compatible with a particular conventional (typically petroleum-derived) fuel. A perfect drop-in fuel does not require adaptation of the fuel distribution network or the vehicle or equipment engine fuel systems, and can be used “as is” in vehicles and engines that currently operate on that particular fuel. Some alternative fuels may become “drop-in” only after blending with conventional fuel to a certain prescribed proportion.

Non-drop-in Alternative Fuel:

An alternative fuel that is not completely interchangeable and compatible with a particular conventional (typically petroleum-derived) fuel. A non-drop-in fuel requires adaptation of (or special treatment within) one or more components of the existing fuel distribution network or the current fleet of vehicle and equipment engine fuel systems. Some alternative fuels must be carefully segregated from conventional fuels, while others may be safely blended with conventional fuels. Some alternative fuels may remain “non-drop-in” even after blending with conventional fuel.

The World Health Organisation is monitoring a new coronavirus variant known as "Mu", which was first identified in Colombia in January, the UN health body said on Tuesday in its weekly pandemic bulletin. WHO has classified Mu as a "variant of interest," saying it has mutations that indicate a risk of resistance to vaccines.

There is widespread concern over the emergence of new virus mutations as infection rates are soaring again, fueled by the highly contagious Delta variant.

Please share if you know more about it.

Biomass fuels have a wide range of different physical and chemical properties. Sustainability of biomass fuels and combustion facilities are depends on the characteristics of these biomass fuels.

Hello guys, I am currently working on the characterization of bio-char produced from high temperature (>1000 °C) pyrolysis of biomass. Unfortunately, I find it difficult to determine the exact char yield.

Firstly, I tried the classic ash tracer method, which was introduced by Badzioch and Hawksley in 1970 and has often been used for determining char yield during coal/biomass pyrolysis. However, I found that the experimental error was a little bit too high.

I wonder are there any methods to correctly determine char yield for my experiments?

Hi,

Will the exchange current density be constant for the case where we use the power of a capacitor for an alkaline electrolyzer to produce hydrogen?, Or should it change when the capacitor current and voltage drop and go down to the low overpotential region.

Also, how can I determine the exchange current density when the electrolyte solution and temperature change?

Voltage and current discharge functions are attached.

I am using these references:

Biomass is considered a renewable and carbon-neutral resource, and is used to prevent the shortage of consumable fossil energy. Among various biomass utilization and conversion technologies, fast pyrolysis to produce bio-oil and char is an effective way to increase energy density and reduce costs. The liquid product, bio-oil, is a complex mixture of water, hundreds of organic compounds, and more or less solid particles. Because of complex composition/low heating value/high oxygen content/strong acidity, bio-oil cannot be directly used for combustion, extraction or transportation of fine chemicals.

Some researchers suggest that blending bio-oil with other solids (e.g. char and coal) can significantly improve the possibility of utilization.

I would like to ask some questions:

ASTM for wood fuels

The grid extension has long been the primary means of electrification of the region. However, connection to the grid is most of the time practically impossible due to geographical remoteness, thick jungles, rugged terrains, high costs of supply, low household incomes, low consumptions, dispersed settlement of consumers, and inadequate road infrastructures. As a result, decentralized diesel generators are most often used for rural electrification in the region. However, the high costs that are associated with the transportation of fuels and the maintenance of those systems make them unsuitable for rural electrification in developing countries. On a world basis, fossil fuel resources are experiencing a rapid depletion, resulting in an ever-increasing price which tends to make them unaffordable for developing nations. The growing evidence of global warming phenomena due to the release of greenhouse gases when burning those fuels is another critical reason for reducing our dependence on them. Therefore, finding alternative energy sources to meet the growing energy demand while minimizing adverse environmental impacts is becoming an imperative task.

Renewable energy sources, namely solar, wind, biomass, geothermal, and hydro, being inexhaustible, locally available, free, and eco-friendly can constitute potential sources of alternative energy, especially for local power generation in remote rural areas. Increasing interest has been given to their utilization since the oil crises of the 1970s.

The main drawbacks associated with the utilization of renewable energy sources are their unreliability and inability to work efficiently due to their intermittent and fluctuating nature, which generally leads to the over-sizing of the system, thereby increasing the investment cost.

Considering uranium & plutonium or other nuclear fuels as a radiating gray gas, can we consider absorption coefficient 'k' same for all? If no, how can we calculate for different fuels?

I want to calculate the equivalence ratio for a fuel air mixture containing two fuels methane and hydrogen and the oxidizer is air.

I am calculating equivalence ratio as, phi=[(wt. CH4+wt. H2)/(wt. of air)]/[(wt. CH4+wt. H2)/(wt. of air)st.]

Is this the correct way of defining the equivalence ratio or I shall multiply the mass fraction/mole fraction of fuels also with their respective masses to get the correct the equivalence ratio?

A number of correlations are available for finding the HHV of solid fuels. Out of those, which suits best for Sewage Sludge?

Electric power producers need a low-cost, reliable power source when wind and solar generators are not able to meet the load requirement. Energy storage for backup such as hydro and batteries have limitations. A "green" renewable fuel that does not add CO2 to the atmosphere may be the best answer. Fuels being considered are:

Methane from waste (limited supply)

Hydrogen from renewable electricity (Handling and storage problems)

Ammonia from the Haber process 3H2 + N2 --> 2NH3 (Low energy and poor combustion)

Methanol from the Olah process 3H2 + CO2 --> H3COH + H2O (Low energy, burns clean)

The bottom two "green" fuels have modest cost and can be stored as liquids at ambient temperature, a very desirable quality. But, could we do better, maybe by blending?

Here is an idea: a blend of ammonia, ammonium nitrate, and methanol?

I confess, I could use some help. Is there another good choice for "green" fuel?

Hello to all of you,

Is there any thesis or research for the question above?

Thank you in advance,

Based on educated guesses, which one of the following promises a better solution to store energy for transportation and grid scale applications:

1) Fuels synthesized form CO2

2) Hydrogen (Ideally Green or Blue Hydrogen in the long run)

I am debating between which one of these two technologies can be a viable alternative to batteries as a medium to store energy.

I know the cost of producing fuels from CO2 is relatively high at present and Hydrogen comes with its own unique challenges like embrittlement and a relatively low round-trip efficiency. But considering all of these factors, which one of the two has a better shot getting a wide scale adaptation?

The idea of using CO2 derived fuels in existing infrastructure is appealing. But at the moment, there seems to be push towards Hydrogen in a lot of places, even though the technology is more expensive than batteries at the moment. Would the cost of Hydrogen would eventually come down with economies of scale and R&D?

And also the supply of precious metals used is a little unsettling once wide adoption picks up.

Thanks

Plants use solar energy to power the conversion of CO2 into plant materials such as starch and cell walls. Plant material can be burnt or fermented to release heat energy or make fuels such as ethanol or diesel.

I am looking for research on how consumers perceive the shift from traditional automotive fuels to biofuels, analyzing consumer behavior and the role of marketing in promoting alternative fuels. Perhaps someone is marketing in a cyclical economy. I would be grateful for any information.

I am currently participating on a reserach project, which aims at introduicng carbon capture technology at LNG fueled ships. But I cannot find a helpful refrence for a marine LNG enigne simulation.

Chemical engineers translate processes developed in the lab into practical applications for the commercial production of products and then work to maintain and improve those processes. They rely on the main foundations of engineering: math, physics, and chemistry (though biology is playing an increasing role). The main role of chemical engineers is to design and troubleshoot processes for the production of chemicals, fuels, foods, pharmaceuticals, and biologicals, just to name a few. Chemical engineers work in almost every industry and affect the production of almost every article manufactured on an industrial scale. They are most often employed by large-scale manufacturing plants to maximize productivity and product quality while minimizing costs.

Students (max of 5 student per group) are asked to write a 10-15 page essay (inclusive picture)

Is power-to-gas a possible solution to this issue? Storing renewable energy in the form of H2 and CH4 and using them as fuels can increase the penetration of renewable energy in the transportation sector?

Actually I am working on a project to study the change of engine parametes of diesel engine using blended fuels like methanol and other hydrocarbons.

As I am totally new to ansys i would like someone to guide or atleast give hint how to start if it is possible.

Thanks in advance

DRDO developed a Hypersonic Test Demonstration Vehicle, a Scram-jet Engine which achieved speed 6 times of sound.

I'm doing bibliographic research about chemical aplications and solutions for sustainable air transport. Following aspects are of interest:

Biggest strange is that secondary fuels are also energy currencies but they are not primary energy sources. How?

We are using butanol diesel blend (10,20 and 30%) for our research work. We submitted our research work to a journal, and reviewer asked to provide following properties of normal -butanol-diesel blends: Cetane number, Latent heat of evaporation, Kinematic viscosity, Density , Lower calorific value etc. how to calculate blend properties.

Is mixture rule alone is  O K?

Or any correlations can be used to find properties of blends.

We would like to measure constant liquid flow rates (no pumps, no oscillations) in a pipe in the range of 0-8(10) kg/h. The liquids to be measured are alcohols, diesel oil, vegetable oil, and similar liquid fuels. The line is pressurized (max. 2 bar(gauge)), and the liquids are at room temperature. Therefore, some corrosion resistance is required if it is invasive or to be built in line. It can be a volume flow meter as well, up to ~10 liters/s. Low uncertainty (at least <=2% at 2.5 kg/h) is a key requirement.

Coriolis mass flow meters are excellent devices, however, the best offer was net 7000 EUR to date which is excessive to our budget. The ideal price tag is up to net 3000 EUR.

Thank you in advance!

About the flame thermal theory , exist an expression simplified to calculate the laminar flame speed for hydrocarbon fuels, its SL= (e^(-E/RT))^1/2 , i want to know in what units should go, including "SL".

Hello to everyone,

I would like to ask everyone IF someone can help me with a research i have to make about "Production and study of the feasibility of increasing its efficiency with the combined use of conventional fuels".

I have searched many resources but i found nothing!

Any link,pdf would be very helpfull for my work!

Thank you all in advance,

sorry for my English :D

Considering both above and underground storage. It is for stationary energy storage that ought to be converted back to electricity later. And is the storage idea behind the hydrogen fueling stations viable for energy storage?

Improving the energy efficiency and environmental sustainability of anaerobic digestion and gasification is still an open challenge: in your opinion, which kinds of technologies will lead to significant research development?

My hypothesis is pregnant women living in a closed environment using kerosene and bio fuels for cooking are at risk of delivering pre mature children when compared to pregnant women using emission free cooking fuels like LPG and electric stoves. I need to have matched controls.

It is observed that development of a new material (even the non-nuclear one) itself takes long time and it may also consume a lot of resources. Over that the nuclear materials (fuels, clad) need elaborate testing in the radiation and the DEC environments. This involves lots of experimental and analytical studies which consumes time. The tall claims (s.a. Fukushima could have been avoided if an ATF was deployed in those NPPs) need to be verified before they can be embedded into the fuel safety codes and the safety analysis codes. More emphasis seems to be laid on the gains in the DBA domain and SAMG, DEC safety margin gains are limited. Is the nuclear community truely aware about the ATF claims and devlopments.

It is understood that most times the output (y) can be dependent on the input (x). My question; is it possible to predict an output with 'no given data' from a set of inputs with available data? For instance, if you want to predict the the torque of an engine (output1, with data) using the fueling level and engine speed as inputs, is it also possible to predict the emission levels (output2, without data) using the same set of inputs?

Thank you!

Hello everyone. Recently, fueled by some friends' testimony on the difficulty of getting Pogonia ophioglossoides to germinate in-vitro, I began a few pilot experiments with the embryos to see if I could induce germination. There's a thesis in the literature that says this orchid can be germinated on K400 medium with peptone, but details about illumination and time to germination are omitted. I can't find the person's contact info either. In any case, I have seeds on K400 or BM2 (which contains peptone) with no additives, either coconut water or banana powder, and both additives, confounded by bleaching time trials. due to difficulty making the medium, i lost about half of my cultures to contamination (not too problematic right now as i am only doing a pilot study). something i noticed, however, is that the embryos are green! can they photosynthesize or react to light? in the thesis i read, a related species did better in the light, even though this is a terrestrial orchid. i put my cultures all under an LED so i could try to get germination. so far, 45-60 minute bleaching and then addition to coconut enriched medium (BM2 is better it seems, and banana makes no difference) has given the largest embryos, but nothing has erupted from a seed coat yet

Octane number and Cetane number are used to characterize the combustion phenomena in petrol and diesel fuels respectively. However, they can be extended to other petroleum fuels also. How these numbers relate to various petroleum fuels?

Fuel dyes are used to differentiate different fuels (diesel, gasoline/petrol, and jet fuels). Solvent dyes (e.g. Solvent Red 24, Solvent Red 26, Solvent Red 164) are used to colour hydrocarbon fuels. But are the fuel dyes harmful to aquatic biota and the aquatic environment if spilled into water bodies?

If you have a publication or information or weblink related to fuel dyes impact on aquatic biota or aquatic environment, please attach with your answer. Thanks

It is said that fossil fuels, particularly oil & gas, comsuption is the main cause of carbon dioxide production that leads to global warming in the last 40 years or so....

If these fuels were not blamed, could any research on cleaner (greener) energies had been easily justified, being so costly? Does anyone have the idea of how much just exponential population increase impacts global temperature? It is clear that the northern hemisphere is the more affected one by this actual temperature increase. Should we start thinking of controlling expansion of human beings on Earth for the sake of the planet (pollution & contamination reduction) and our own survival? Just out loud thinking!!!!

Gas turbines use solid or liquid or gaseous fuels. Name the fuels used.

Lot of research is going on to invent an alternative source of conventional fuel in place of Diesel because petroluem fuels are depleting. Out of which, biodiesels are found to be reliable source of fuel however, this suffers with high NO_x emissions. Exhaust gas recirculation has been used to reduce the same. Various forms of biodiesels are prepared and tested (performance wise, exhaust gases and chemical analysis) and found suitable to use in diesel engine. However, there is a limited usage. What could be its limitations in brief?

In view of the increase in power demand, the power plants have gone starting from therrnal, hydel, gas and latest to nuclear power generation. Nuclear power plants has application not only for power generation, but also now been used in space applications. Recent advancements are developed in this area since a small amount of nuclear fuel gives more and more energy compared to other conventional fuels. In view of this, what are the recent developments in nuclear research in terms of fuels and their recent adoption methods.

Having just read about the different kinds of plastics being used in producing single-use containers, and then being thrown away, causing harm to the environment and the life that is in it, I wonder what is the proportion of the total petroleum from wells that is being used for making these non-biodegradable materials. At least with the huge quantity of CO2 from burning fuels, there is a gradual return of this gas and its absorption back into nature, but the plastics don't have this feature, so we may expect the quantity of these waste plastics to grow until we run out of oil!

Tier 1 method for emission inventory calculates the emission on the basis of amount of fuels burnt by directly calculating the amount of product using stoichiometric equation.

How much sulfur dioxide is produced in Kg's when 1 litre of Diesel is burnt by vehicles?

Alright, I am trying to find LHV for a liquid fuel. Let's say the fuel is a type of gasoline. The first thing that came up to my mind was to perform elemental analysis, then calculate HHV using Dulong and Petit equation, then convert to LHV using this equation:

LHV = HHV – 2400 ( M+9H2) kJ/Kg

I know EDS is not an option, I also doubt whether GC-MS might be helpful.

I don't really know any other liquid fuel elemental analysis instruments. If someone's willing to share an insight, I'd be very grateful.

Thanks in advance

Green electricity is the cleanest, most beneficial forms of renewable energy. For example, municipal solid waste or large scale hydro-power are indeed renewable but still have major polluting capacity. These are the energy sources considered to provide green electricity. Currently, the usable energy is basically harvested from the fossil energy sources, including coal, oil, and gas, which are believed to harm the environment due to the emitted GHGs. The awareness to the climate change and limited reserve of fossil energy sources has led to a strong motivation to develop a new energy system which can facilitate three important pillars: security, clean environment, and economic opportunity. This future energy system is strongly expected to be able to blend both fossil and renewable energy sources, while minimize its environmental impacts. To realize it, the primary energy sources are converted to the efficient secondary energy sources, including electricity and hydrogen. These two kinds of secondary energy source are considered very promising in the future, following a high demand in many sectors. In transportation sector, both electricity and hydrogen are believed to become the future fuels as the deployment of electric and fuel cell vehicles is increasing rapidly.

How Promising for

A low-carbon fuel standard (LCFS) is a rule enacted to reduce carbon intensity in transportation fuels as compared to conventional petroleum fuels, such as gasoline and diesel.

I want to find the laminar speed of some fuels by experiment. There are different methodology and configurations. is there any reference that compare these and explain when we should use these configurations?

I would like to know if the lubricant properties of internal combustion engines are affected by the use of ethanol, aqueous ethanol solutions or ethanol-Diesel blends as fuel, especially for Diesel engines operating with such fuels.

We have a lab of batteries and fuel cell where we usually work with fuels other than hydrogen like formic acid/ methanol/ NaBH4/etc. A new student has purchased a hydrogen cylinder to use it as fuel in PEMFC. Is it safe to use hydrogen cylinder in laboratory as a fuel? I mean is there any chance of explosion/fire in fuel cell during H2/O2 reaction or can there be any source of ignition/spark inside fuel cell during fuel cell testing as we dont have any automatic shut down system for hydrogen.

Global Energy Demand: Where are we heading towards?

Has global energy mix really shifted to low-carbon fuels?

Has energy solution really varied over time and circumstances?

Whether the energy impact on economy, security and environment has really taken a divergence in the recent past?

10 billion - world population - by 2050 - Do we really need something more than fossil and renewable energies?

Can China and India really meet their rapid rise in energy demand with ease?

Electricity from solar and wind looks really impressive as of now.

Can it maintain its same exponential growth for the next couple of decades?

Can we expect CO2 emission to attain its peak well before 2050??

Hi all,

Currently, I simulated the SI engine fueled with natural gas/hydrogen blends. Generally, the GRI 3.0 is widely used in the natural gas engine in modelling community. however, we want to investigate the performance, combustion and emission of the SI engine fueled with natural gas/hydrogen blends. Can we only use the GRI 3.0 mechanism to mimic the natural gas/hydrogen blends? Or need to combine the hydrogen mechanism and the natural gas mechanism?
