In this study, a green, efficient and economic process for biodiesel production using ion exchange resin as heterogeneous catalyst was investigated. [Display omitted] ► The mechanism of transesterification reaction catalyzed by ion exchange resins was illustrated. ► A kinetic model was established for analyzing the transesterification process. ► A green, effective and economic technology for biodiesel production was developed. In this study, biodiesel production from yellow horn (Xanthoceras sorbifolia Bunge.) seed oil using ion exchange resin as heterogeneous catalyst was investigated. After illustration of the mechanisms of transesterification reactions catalyzed by typical ion exchange resins, the factors affecting microwave-assisted transesterification process were studied. A high conversion yield of about 96% was achieved under optimal conditions using high alkaline anion exchange resins as catalyst. Analyzing the FAMEs composition by GC–MS and main physical–chemical properties demonstrated that the biodiesel product prepared from yellow horn seed oil was of high quality. Compared with conventional alkali catalyst, the outstanding characteristics of reusability and operational stability made the resin catalyst more predominant for biodiesel production. In addition, a comprehensive kinetic model was established for analyzing the reaction. The results of present research showed that microwave-assisted transesterification process catalyzed by high alkaline anion exchange resin was a green, effective and economic technology for biodiesel industry.
