摘　　要：用自制的SO_4^(2-)/La_2O_3-ZrO_2固体超强酸催化剂催化废弃油脂与乙醇进行酯化/酯交换反应,制备生物柴油。结果表明,在醇油比11:1,催化剂用量2.0%,80℃下反应4 h,生物柴油的酯化率可达93.2%。用气相色谱-质谱联用仪对所得产品进行表征分析,表明其主要成分为C_(16)~C_(18)脂肪酸乙酯,且纯度高。Using self-made SO42-/La2O3-ZrO2 solid superacid as catalyst, the biodiesel was prepared by esterification with ethanol. The experiment result showed that under the condition of the reaction temperature of 80 ℃, reaction time of 4 h, the ethanol/oil ratio is 11：1 and catalyst amount is 2.0 %,yield of biodiesel can be obtained 93.2 %. The prepared biodiesel was characterized by GC/MS, which indicated that the product was of high purity and its main component was fatty acid ethyl ester（C16C18）.
