Abstract

A heterogeneous KF/Ca-MgO catalyst was prepared by impregnation method, and was characterized by Tanabe method, BET and X-ray diffraction.  The effects of weight KF addition, temperature and time of calcination on catalyst preparation were investigated. The influence of basicity value of catalyst also was investigated. KF/Ca-MgO catalyst can performed the active compounds to produced a high MG yield of 49,76% for 2%w KF addition, at 5500C of calcination temperature and 2 hours of calcination time. It is has a high spesific surface area (110,924 m2/g) that favorable for contact between catalyst and substrates which effectively improved efficiency of glycerolysis. The high activity of the catalyst was described to the formation of KCaF3 and MgKF3 crystals.
