摘要:
采用共沉淀-浸渍法制备了SO2-4/Fe2O3-TiO2固体酸催化剂,并用于催化山苍子核仁油与乙醇制备生物柴油,优化了制备生物柴油的工艺条件。结果 表明,在醇油摩尔比为16∶1,催化剂用量为10.0 %(w),在乙醇回流温度(78 ℃)下反应8.0 h,生物柴油产率可达44.9%,表明该催化剂对山苍子核仁油制备生物柴油具有较高的活性。 

Abstract:
By the method of coprecipitation and wet impregnation, the solid acid catalyst of SO2-4/Fe2O3-TiO2 was prepared and used to catalyze litsea cubeba kernel oil and ethanol to prepare biodiesel. The preparation conditions of biodiesel were optimized. The results showed that when the molar ratio of ethanol to Litsea cubeba kernel oil was 16∶1, the catalyst dosage was 10.0 wt%, the reaction time was 8.0 h at ethanol refluxing temperature of 78 ℃, the biodiesel yield reached 44.9%, which indicated that the catalyst has higher catalytic activity for biodiesel production.
