Nowadays, biodiesel is an alternative fuel to replace the existing petroleum-based diesel. The advantages of biodiesel … are good combustion efficiency, high-lubricity, biodegradability and low toxicity. Biodiesel can be an alternate fuel to … commercially improve the transesterification by using homogeneous base catalyst, e.g. sodium hydroxide or potassium hydroxide. By …

in the production of biodiesel is transesterification, and using a methanol–ethanol mixture will combine the advantages …In recent years, biodiesel has attracted significant attention from researchers, governments, and industries as a … promising biodiesel feedstock despite its drawbacks, such as its high free fatty acid (FFA) and water contents. This review …

feedstock for the production of a biodiesel fuel. Biodiesel was prepared from peanut by transesterification of the crude oil … with methanol in the presence of NaOH as catalyst. A maximum oil to ester conversion was 89%. The viscosity of biodiesel … biodiesel is most important for engine part of view and various standards have been specified to check the quality. The …

This study demonstrates a direct transesterification (DT) method for reliable quantification of microalgal lipid …. Primary screening of various transesterification methods and the types of biomass (wet, oven dried and lyophilized) were … cell weight). Further optimization of transesterification parameters for selected method using response surface methodology …

The highly efficient procedure has been developed for the synthesis of biodiesel from vegetable oil and methanol. The …

problems were not observed for LOME blends. Hence, process of transesterification is found to be an effective method of …

In the present study, waste rapeseed oil with high free fatty acids (FFA) was used as feedstock for producing biodiesel …. In the pretreatment step, FFA was reduced by distillation refining method. Then, biodiesel was produced by alkaline …-catalyzed transesterification process, which was designed according to the 24 full-factorial central composite design. The response surface …

Coconut oil having 12.8% free fatty acid (FFA) was used as a feedstock to produce biodiesel by a two-step process. In …-to-oil ratio, catalyst concentration, reaction temperature, and reaction time. Methyl ester content of the coconut biodiesel was … determined by GC to be 98.4% under the optimum condition. The viscosity of coconut biodiesel product was very close to that of …
