应用山苍子核仁油制备生物柴油的研究

采用共沉淀-浸渍法制备了 SO 2-4/Fe2 O 3-TiO 2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。...

By the method of coprecipitation and wet impregnation,the solid acid catalyst of SO 2 -4 /Fe2 O 3-TiO 2 was prepared and used to catalyze litsea cubeba kernel oil and ethanol to prepare biodie-sel.The preparation conditions of biodiesel were optimized.The results showed that when the molar ratio of ethanol to Litsea cubeba kernel oil was 1 6∶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.
