摘要

结果表明，溶胶-凝胶法制备的KF/γ-Al2O3催化剂在甲醇和菜籽油酯交换制生物柴油的过程中比浸渍法制备的KF/γ-Al2O3催化剂具有更大的活性。以KF/γ-Al2O3为原料，以KF与γ-Al2O3的摩尔比为1.3:1制备的生物柴油收率最高(96.5%)。菜籽油转化为生物柴油的高转化率是由于KF/γ-Al2O3具有较高的碱度和比表面。

Conversion of Rapeseed Oil to Biodiesel on KF/γ-Al2O3 CATALYST

It is shown that the KF/γ-Al₂O₃ catalyst obtained by the sol–gel method has a greater activity in the process of transesterification of methanol and rapeseed oil to biodiesel compared to KF/γ-Al₂O₃ prepared by impregnation. The highest yield of biodiesel (96.5%) is achieved with use of KF/γ-Al₂O₃, prepared at molar ratio KF to γ-Al₂O₃ 1.3:1. High conversion of rapeseed oil to biodiesel is explained by the relatively high basicity and specific surface of KF/γ-Al₂O₃.
