This work focuses on the development of heterogeneous catalysts for biodiesel production from high free fatty acid (FFA …) containing Jatropha curcas oil (JCO). Solid base and acid catalysts were prepared and tested for transesterification in a batch …-step simultaneous esterification and transesterification. More soap formation was found to be the main problem for calcium oxide (CaO …

Heterogeneous basic catalysts can be used for biodiesel production. The performances of several types of such materials …

Biodiesel either in neat form or as a mixture with diesel fuel is widely investigated to solve the twin problem of …, emission and combustion characteristics of biodiesel derived from non edible Jatropha oil in a dual fuel diesel engine with … found to be higher. However, HC, CO and CO2 and smoke were found to be lower with Jatropha biodiesel fuel. NOx emissions on …

Interest in biodiesel research has increased over the years due to diminishing petroleum reserves but biodiesel has to … conversion of non-edible seed oil, Calophyllum inophyllum with free fatty acid of 15% into biodiesel over biomass …

In this review, recent development of glycerol-free supercritical fluid transesterification for biodiesel production … was discussed. Glycerol-free supercritical fluid processes including single-step and two-step transesterification for … biodiesel production were reviewed and subsequently the advantages and limitations were highlighted. Value-added by-product from …

Biodiesel is gaining acceptance in the market as fuel and lubricant. It is expected that biodiesel industries will … rapidly grow worldwide in the coming years and information on biodiesel feedstock, production, and characteristics will be … biodiesel. In the present paper, a comprehensive review is reported on feedstock, production technologies, and characteristics …

Methanol was replaced by dimethyl carbonate for biodiesel production. In the process, fatty acid methyl ester (FAME …) was produced through transesterification of soybean oil with dimethyl carbonate (DMC) using potassium methoxide as a …

Biodiesel as a biodegradable, sustainable and clean energy has worldwide attracted renewed and growing interest in … topical years, chiefly due to development in biodiesel fuel and ecological pressures which include climatic changes. In the … production of biodiesel from biomass, separation and purification of biodiesel is a critical technology. Conventional …

, neem and cotton seed oil) were used to optimize the biodiesel production process variables like catalyst concentration … biodiesel in cold weather conditions, but for hot climate condition biodiesel obtained from the remaining oil sources is …

In this investigation, Mahua Oil Ethyl Ester was prepared by transesterification using sulfuric acid (H2SO4) as …
