Carbon dioxide is a greenhouse gas with anthropogenic evolution and is primarily responsible for global warming. To capture CO2 gas from industrial and also direct atmosphere, different mitigation methods absorption, adsorption and hydrates, are used. In the last decade, deep eutectic solvents (DESs) are considered to be benign CO2 absorption solve...

This research investigates the catalytic effect of activated charcoal, MgCO3, and ZSM-5 in a batch-pyrolysis reactor with a Low-Density Poly-Ethylene (LDPE) feedstock on pyro-oil yield. Initially, trials with the ZSM-5 catalyst were conducted at various temperatures ranging from 300 to 600 °C, in which 500 °C temperature offered a higher pyro-oil y...

This paper deals with the experimental investigations and thermodynamic studies carried out for five distinct temperatures ranging from 300-500℃ with a heating rate of 10℃/min. This work aims to study the influence of pyrolysis temperature on product (biochar, bio-oil, syngas) yield, its physicochemical properties and energy yield. The experiments...

Non-biodegradable plastics polymers, such as low-density polyethylene (LDPE), polystyrene (PS), and polyvinyl chloride (PVC) are non-biodegradable and release toxic gases into the environment on combustion and after long use. This study includes the screening of a series of organic solvents for solubility parameters of LDPE and PS. The Karanja biod...

The concentration of carbon dioxide gas has accelerated over the last two decades which cause drastic changes in the climatic conditions. In industries, carbon capture plants use a volatile organic solvent which causes many environmental threats. So, a low-cost green absorbent has been formulated with nontoxicity and high selectivity properties for...

Global warming reaches an average of up to 425 ppm in May 2020 with an increasing rate of CO2 emissions. The outcome is the melting of icebergs and seriously affected biodiversity. Therefore, demand was raised for the creation of new mitigation approaches to effectively catch it. Developing cost-effective, environmentally sustainable, and productiv...

Dye-Sensitized Solar Cells (DSSCs) or Grätzel cells have attracted widespread attention due to their low cost, ease of fabrication, and reasonably good photochemical conversion efficiency. The photochemical efficiency of solar cells mainly depends on their design, development, electrodes, and electrolyte used. The use of conducting polymers in sola...

A great threat is faced by environment and ecosystems due to a continuous increase in temperature on a global scale. Large emissions of carbon dioxide from various thermal power plants are the major concern, besides vehicular emissions. But, the compositions of flue gases from thermal-power plants consist of only 11-15 % v/v of carbon dioxide. At l...

Many chemical processes require use of a solvent. Due to the adverse environmental effects of volatile organic compounds (VOCs), there is a need for replacement of traditional volatile solvents and hence a rising interest among researchers in the field of non-volatile solvents. A large number of chemical reactions are carried out in the presence of...

Heterogeneous photocatalysis refers to the series of oxidation and reduction reactions on a semiconductor surface by the electrons and holes generated by absorption of light by the catalyst. This method is widely used for the degradation of dyes and their mixtures present in the textile effluent, and involves two main aspects, viz. a photocatalyst,...

The inaccessibility and poor water quality continue to pose a major threat to human health worldwide. Around billions of people lack access drinkable water. The water contains the pathogenic impurities, which are responsible for water‐borne diseases. The main purpose to write this chapter is to spread knowledge of the quality of the available water...

In the past few years, the researchers have paying attention on the core-shell microspheres due to excellent applications. In essence, core-shell microspheres have unique composition which makes them distinguishable from other particle types. These microparticles exhibit the combined properties of both core and shell materials. In addition, they ex...

In every chemical process industry, solvent plays a very important role mainly, in separation, by extraction, and also as a reaction intermediator, and promoter. The conventional organic solvents still in use in many industries are volatile organic compounds (VOCs) which are responsible for environmental pollution and health hazards to public. Repl...

Gasification of lignite in the presence of MgCO3 as a catalyst was carried out in 10 kWe pilot scale (atmospheric pressure) downdraft gasifier. The main disadvantage with lignite is the clinker formation at high temperature. To overcome this problem, MgCO3 lumps were used as a catalyst with lignite. The experiments were carried out with four differ...
