Catalytic behavior of La2O3 promoted SO42−/ZrO 2 (SZ) in the simultaneous esterification and transesterification palm oil with 10 wt% myristic acid was studied. (90 purity) derived from domestic monazite ore introduced into SZ by impregnation method. Effects loading reaction parameters on conversion were also investigated. The 20 wt%La2O3-SZ catalyst possessed dual strong basic sites which could efficiently promote both reactions. Using catalyst, initial rate reactions faster, equilibrium reached faster. total fatty methyl ester (FAME) content 74.51 (MAME) 8.41 achieved. maintained a relatively stable catalytic during three cycles. No significant loss activity for observed after reusing five times without regeneration.
