Abstract: Continuous-flow reactive distillation technique was used to prepare biodiesel fuel from vegetable oil. The results showed that said technique exhibited faster reaction rate, higher conversion, better selectivity and easier separation of glycerol as compared with the conventional CSTR technique. As a result, to reach the same conversion a single stage transesterification was needed instead of two or three reaction stages.

Key words: biodiesel, reactive distillation, transesterification
