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.
