Questions related to Biorefinery
I am trying to model lignocellulosic biorefinery on Aspen Plus.
I also want to know which fluid package i need to select for simulation as the process flow sheet has electrolyte and biomass. The database file is attached.
Good afternoon, I am a student of ING chemistry, could you help me with information on the subject of Biorefineries for my thesis.
I know different people will have different answers depending on their backgrounds.
Think in terms of Chemicals for a biorefinery
Integration of the mass culture into the economy
life cycle assessments
At present any company or firm produces chemicals and fuel from macroalgal biomass on a commercial scale using the biorefinery approach?
In particular I would like to have data on the evolution in enzyme production costs for cellulase, hemicellulase and other enzymes related to biorefineries and biomass.
Are any of you assessing the environmental sustainability of biorefineries using SimaPro? Is there any database with the most suitable data for yeast and enzymes? For yeast, Ecoinvent has Fodder Yeast but in my opinion it is not suitable since it does not represent the impacts of Saccharomyces cerevisiae. And in the case of enzyme, the database Agribalyse has gluco-amylase with empty values which does not help at all.
Could you please tell me what is the best methodology to evaluate the impacts of these two elements?
Wanted modern information relating to the energy aspects of mechanochemistry (total energy costs of the process, the yields of reactions or elementary acts...etc) The main interest is in the mechanochemistry of organic molecules and polymers, but inorganic materials are also welcome.
Any articles, reviews, links will be helpful! Thank you
Most of the biorefinery concepts be it wealth from waste or developing new strains with modifications, require atleast two combinations of solvents derived from fossil fuels or petrochemicals. So, is this biorefinery concept really an alternative to fossil fuels and way to sustainable development?
I will be looking into the sustainability of an algae value chain using Porphyridium as a feedstock. A biorefinery could produce proteins, sugars en phycoerythrin (PE) from the Porphyridium algae. However, which value chain should I use as a comparison scenario (=a reference case)? In other words, which (fossil) feedstocks can be replaced by the Porphyridium algae and why does it offer an advantage to produce proteins, sugars and PE from the algae?
Thermochemical treatment of biomass produces bio-oil which is more oxygenated and is quite unstable. How can it be converted to simpler aromatics?
Why they are important for biorefinery?
For I+D+I from bench to pilot plants for biorefinery plants, do you think that a Social and Environmental Life Cycle assessment is good enough as a tool to provide some technology transfer indicators?
Hi everyone. I would like to know if any of you know of an existing jatropha biorefinery? It can be one at a pilot, demonstration or commercial scale.
I just need very simple information about such biorefinery, such as a rough material/energy balance for the main streams of the biorefinery (like the products, the amount of energy that is produced, etc). This is to be used in a school assignment, so data don't need to be that precise.
If you could be kind of recommending any reference I would be very grateful!
Tks a lot!
One of the great challenges is to find a sustainable way to obtain biobased products from renewable resources. A significant emphasis has been on the developmental biorefinery concept and maximizing the exploitation of biomass into value-added products for utilization in Metallurgical Industries.
how do I establish a process development for integration of nanocellulose in biodiesel/bioethanol in a biorefinery or oscillaory baffled reactor?
Is it feasibility and what will be the implication on the liquid biofuel?
What will be the impact of nano particle on the liquid biofuel?
I have read articles about using flotation to separate a variety of materials, and of course, the majority application of this tech is used in mining. However, I can only find quite a limited number of papers talking about using flotation to harvest cells or microbes, such as E.coli, and most of those papers are quite old (around 1960 to 1970s). I don't know why people nowadays don't talk about its application in microbe separation like other methods, such as ultrafiltration and centrifugation. Is there any critical fact that I missed kicking this method out from the industry of microbe separation, or could it because this method is so classic that people don't waste a word to talk about it?
We are searching partners to apply to ERANET LAC (ERANet-LAC 3rd Multi-Thematic Joint Call 2017/2018 involving Research Infrastructures). We are interested in apply anaerobic digestion technologies in tanneries like an alternative to resolve environmental problems that arise of organic waste which are generated in the first phases of this industrial process and to propose their use like a renewable energy source and organic fertilizer
Currently, I work on microalgae pre-treatment from Biorefinery sector. Does anyone have an idea how to separate microalgae from Biorefinery using vortex bioreactor as pre-treatment?
I would appreciate it if you could assist for your help.
Life Cycle Analysis plays significant role in many research proposals and is one of the main significant criteria that exist during the evaluation process. It’s mainly used (beside others) to calculate the carbon footprint of several operations and or several procedures. However, remain unclear if a complete and detailed LCA can be done, in order to compare with the state of the art. In addition, this because systems boundaries can change all the time. What is your opinion?
What are some industrial scale examples of biorefinery systems/integrated biorefineries worldwide that produce biofuels or chemicals from biomass?
When considering microalgae growing and utilising via high value product extraction followed by anaerobic digestion - can anyone name companies worldwide already working on this full-scale?
Many thanks in advance.
During high-solids enzymatic hydrolysis, water was constrained in biomass solids due to the interactions between solid and water. Water constraint obviously decreased the efficiency of enzymatic hydrolysis. So, how can I remove the water constraint and increase the performance of high-solids enzymatic hydrolysis?
What is the best way to extract lignin and hemicellulose from a raw sample in preparation of cellulose nanofibers?
I am writing to ask a question regarding biorefinery (bioethanol, steam and electricity production) annexed to sugar mill. Considering sugarcane bagasse and tops/trash as feedstock, and steam explosion as pretreatment method, is biorefinery capable to supply steam and electricity demand of sugar mill as well as biorefinery process? Literature data is not clear about it.
The Global Crowdmapping of Biorefinery Initiatives is a nonprofit platform designed to visualize key initiatives as well as trends in the field of Biorefinery developments on a world scale.
The saps of the Asian Palmyra palm (Borassus flabellifer, also known as lontar palm, toddy palm or wine palm) and the sugar palm (Arenga pinnata, common names including arenga palm, black sugar palm) are suppliers for sugar and are fermented to yield alcoholic beverages. These Palm trees are mainly wild growing. Making palm sugar is an occupation that many villagers do after rice harvest to earn additional income.
Are there any projects for the cultivation of the Palmyra and/or Sugar palm in plantations in order to use them as a feedstock supplier for bioethanol or would the sap of the Oil palm (Elaeis guineensis jacq.) be rich enough in sucrose to be considered for such purpose? Appropriate references or electronic links to publications about such projects would be welcome.
