Abstract: Heterogeneous continuous process is the development direction of commercial production of biodiesel. The development of heterogeneous catalyst and new process has been the focus in the field of biodiesel，which is also the key to achieving green，economical，efficient production of biodiesel. The possible reaction mechanisms of transesterification reaction were discussed. The research status of solid acid-base catalysts was reviewed. The excellent catalytic performance and the existing problem of the solid acid-base catalysts were reported. A variety of new multiphase biodiesel reactors were introduced，especially the reaction-separation coupled technologies used in biodiesel production. At last，the future development of biodiesel was also presented. The development of new acid-base bifunctional catalyst and advanced multiphase continuous reaction-separation coupled process will promote development of biodiesel.
