地沟油与醇类酯交换制备生物柴油的研究

Study on Transesterification between Waste Oils and Methanol on Multiple Metal Oxides Catalyst

以SrO-Al2O3为催化剂,甲醇、乙醇、异丙醇为酯交换试剂制备生物柴油,甲醇、乙醇、异丙醇酯交换的最佳反应时间为60、90、90 min;反应温度为50、70、80℃;催化剂使用量都为5%;催化使用次数分别是3、3、4次。选择酯试剂顺序为甲醇>乙醇>异丙醇。

The use of SrO -A12O3 catalyzed preparation of biodiesel, methanol, ethanol, isopropanol transesterification exchange the optimal time of reaction 60 , 90 , 90 min;the temperature of reaction 50 , 70 , 80 ℃; the dosage of catalyst was 5 %; times of catalyst 3, 3, 4 times. Transesterification was Selected methanol〉ethanol〉isopropanol.
