Abstract: Present work aimed for the synthesis of a promising MTSA-Si catalyst and its application for biodiesel preparation using WFO. It has been illustrated from the experimental results, the most favorable reaction conditions for the biodiesel preparation using WFO are (i) 1:10 oil to methanol molar ratio, (ii) 5% MTSA-Si catalyst (w/w), (iii) 130 °C reaction temperature and (iv) 10 h reaction time, for the 98.22% yield of biodiesel. The side product raw glycerin was further transformed into the triglycerides over MTSA-Si catalyzed lauric acid esterification. The fuel properties of biodiesel were estimated and correlated fuel standards.

Abstract: Industrial based research project using different types of solid/liquid waste for energy generation and replacing conventional fuel-coal partially by solid/liquid waste has been investigated. Pollutant produced CO2 during combustion of solid/liquid waste can be utilized conveniently for algae cultivation. Further algae so cultivated can be converted into energy either in the form of carbohydrates or lipids. This can be further converted into bio-fuels like bio-ethanol and bio-diesel. All these aspects have been analyzed critically in this paper for typical Cement Manufacturing Unit wherein fuel utilized-coal has been partially substituted by solid/liquid waste. Further, use of hydrogen as a fuel-an alternative clean fuel of tomorrow has also been highlighted in this research project.

Abstract: An efficient, cleaner and environment benign Knoevenagel condensation of aromatic aldehydes with 3-methyl-5-pyrazolone using TEAB in water media is described. The reaction is highly chemoselective with no side reactions. The procedure does not involve the use of any additional reagent/catalyst, produces no waste, and represents a green synthetic protocol.
