Review of Ionic Liquid as a Catalyst for Biodiesel Prodution

บทคัดย่อ

Applications of ionic liquids (ILs) for biodiesel production attract more interest from the research and development sector because of their high environmentally and environmental friendly properties. IL's play multiple roles as solvent, co-solvent, catalyst, or catalyst support in transesterification and esterification. In this study, their functions and efficiencies for biodiesel production are described. IL performance potentially overcomes some limitations of conventional process that used base, acid, or enzyme as a catalyst because its chemical structure could be tailor-made designed and modified by changing different anion and cation. Lastly, in this study the recycle methods of IL in the process are also presented to reduce the high cost of IL for biodiesel production.
