| Abstract: | SO2-4/Fe2O3,A solid acid catalyst,is prepared and used to produce biodiesel through transesterification.The factors affecting catalyst preparation and biodiesel production are investigated.It’s found that SO2-4/Fe2O3 exhibits high catalytic activity for transesterification under the conditions of the concentration of the impregnation sulfuric acid 0.5 mol·L-1,roasting temperature 600℃,roasting time 3 h.And the esterification rate is 63.2% under the optimum preparation conditions for biodiesel as follows:catalyst amount is 3%,reaction temperature is 70℃,reaction time is 2 h,the molar ratio of methanol to oleic acid is 2∶1. |
