Application of transesterification for the production of biodiesel

Zhang Huaiyuan,Song Yuanda

Strategic Study of CAE 2010, Volume 12, Issue 1,   Pages 24-29

Abstract: Several transesterafication methods can be used to produce biodiesel, such as, homogeneous acid/basecatalysis, lipase-catalyzed reaction, supercritical method and solid acid/base catalysis.Homogeneous acid/base catalysis is very fast and with high efficiency, but down-stream product is difficultSolid acid/base catalyst, which can be recycled, has less causticity and without pollution.Supported solid base catalysis will be the main trend for biodiesel preparation by transesterification

Keywords： biodiesel     transesterification     homogeneous acid/base     solid acid/base     lipase     supercritical method
