复合氧化物催化地沟油制备生物柴油的研究

摘要

研究了以SrO-A1203为酯交换催化剂，利用廉价地沟油制备生物柴油。得出地沟油制备生物柴油酯交换的最佳反应时间、反应温度、催化剂使用量和催化使用次数分别是：60 min、60℃、4%、3次，最高甲酯生成率达92.4%。制备的生物柴油达到国家标准，在闪点、冷凝点等方面要优于0#柴油。%The preparation of biodiesel was studied,whose raw material was waste oil and transesterification catalyst was SrO-A1203. The best transesterification reaction condition was that time,temperature,catalyst amount and catalytic times respectively is 60 min,60℃,4%,3 times,and the highest of methyl esters rate of 92.4%. The biodiesel reached the national standard, superior to 0# diesel in the flash point, freezing point.
