摘要

以TiO₂为载体,通过浸渍法制备了KNO₃/TiO₂固体碱催化剂。通过X射线衍射(XRD)和扫描电镜(SEM)对催化剂进行了表征,同时探究了催化剂制备和酯交换催化反应的优化条件。结果表明:催化剂焙烧温度为600℃、焙烧时间为3.5h、催化剂用量(占大豆油的质量)为2.5%、醇油物质的量比为12、反应时间为3h时,生物柴油的产率最高达92.8%。

Abstract

KNO₃/TiO₂ solid base catalyst was prepared by impregnation method using TiO₂ as support.The catalyst was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).At the same time,various optimization conditions for the preparation of the catalyst and the transesterification catalytic reaction were investigated.The results showed that when the catalyst calcination temperature was 600℃,the catalyst calcination time was 3.5h,the catalyst dosage (the mass of the catalyst in soybean oil) was 2.5%,the molar ratio of alcohol to oil was 12,and the transesterification reaction time was 3h,the biodiesel yield can reach up to 92.8%.
