Chapter 16 - Lipid-derived biofuel: Production methodologies

Abstract

The most prime challenge in biodiesel production is the proper selection of feedstock. Apart from the cost and other requisite properties of feedstock, an economical and opportune production methodology is to look forward to the biodiesel synthesis. This chapter predominantly handles the various methodologies adapted for the production of biodiesel. A review on new technologies revamped for the highest possible yield of biodiesel is conferred. Direct blending, transesterification, pyrolysis, microemulsion, and novel emerging techniques say supercritical methodology for the biodiesel production have been discussed. The pros and cons of each method have been analyzed. The important properties of synthesized biodiesel have been discussed for any significant change due to the production methodology. This biofuel is majorly derived from a lipid source. The main raw material for biodiesel is the fatty acids derived from vegetable source, animal fat, waste cooking oil, and algal oil. Transesterification is the most desired method for the synthesis of biodiesel as the quality of the fuel is high, compared to other methods. Significant parameters to be maintained, different catalysts utilized, and process conditions for the conversion of fatty acids to biodiesel are reviewed in detail.
