摘　　要：用活性白土处理回收的生活污油,以固体超强酸STL为催化剂,与甲醇进行酯交换,制备生物柴油。结果表明,回收的生活污油经处理,可用于生物柴油的生产。在醇油摩尔比7∶1、反应温度65℃、反应时间150min、催化剂(w%总物料)1.2%的条件下,生物柴油酯化率达到96.5%。采用气相色谱分析产品成分,纯度达98.2%,达到德国生物柴油质量标准。Life waste oil was treated and bleached by active bleaching earths.Using rare earth composite solid super acid STL as catalyst,the biodiesel was prepared by transesterification with methanol.The results showed that the treated waste oil issuitable for the production of biodiesel.Under the condition of the methanol/oil ratio as 7∶1,at the temperature of 65℃,1.4% wt the total material of catalyst and reaction time of 150 min,the esterification rate of biodiesel can be obtained 96.5 %.The product compositions were analyzed by GC/MS and purity reached 98.2%,which complies with Germany biodiesel quality standards.
