摘要:         以NaHSO4·H2O、正硅酸乙酯和异丙醇为原料,经溶胶—凝胶法制备固体酸催化剂(NaHSO4·SiO2),进行了利用此催化剂催化油酸与甲醇的酯反应制备生物柴油的实验,研究了催化剂焙烧温度、NaHSO4负载量、反应时间、催化剂质量分数、甲醇与油酸物质的量比等对油酸转化率的影响。实验结果表明:固体酸催化剂NaHSO4·SiO2在油酸与甲醇的酯化反应中具有很高的催化活性,当催化剂焙烧温度为200℃、NaHSO4负载量为15%、n(甲醇):n(油酸)=10:1、催化剂质量占油酸质量的10%、反应时间5h时,酯化反应转化率可达95.19%。

Abstract: Solid acid catalyst NaHSO4·SiO2 was prepared by sol-gel method from NaHSO4·SiO2, TEOS and isopropyl alcohol, and applied in the biodiesel production with the esterification reaction of oleic acid and methanol. The factors including catalyst calcination temperature, NaHSO4 loading, reaction time, catalyst amount, reactants molar ratio methanol to oleic acid on the biodiesel yield were investigated. The experimental results show that solid acid catalyst NaHSO4·SiO2 has high catalytic activity, the esterification reaction conversion can reach 95.19% under the following optimal conditions: catalyst calcination temperature 200 ℃, NaHSO4 loading 15.0%, reaction time of 5.0 h, n(methanol)∶n(oleic acid)= 10∶1 and weight ratio of catalyst to oleic acid 10∶1. 
