Lipase Catalysis for Transesterification Produces Biodiesel Using Coconut Oil as Main Raw Material Source
Tran Thi Be Lan, Phan Ngoc Hoa
Abstract: Transesterification is a chemical method that has been studied to convert fat and oil into biodiesel. Inorganic catalysts often have high catalysis activity and reusability, so they have been predominant for biodiesel production at the industrial scale; however, they often cause severe pollution. Recently, bio-catalytic transesteriﬁcation has received considerable attention due to its favorable conversion rate and relatively simple processing performance for the production and puriﬁcation of biodiesel. In this study, two lipases from Candida rugosa and Porcine pancreas was used to catalyze the transesterification of coconut oil in order to produce biodiesel. The results have shown that the catalysis ability of the lipase from Candida rugosa in the transesterification of coconut oil is better than that of Porcine pancreas. The use of the lipases from Candida rugosa and Porcine pancreas reached the oil conversion level of 62.55% and 59.72%, respectively. The better conditions of the enzymes and the reaction were also studied.
Keywords: Transesterification, lipase, Candida rugosa, Porcine pancreas, biodiesel, coconut oil.
