Abstract


This article describe about the study of produce fuel from palm fatty acid distillate with a similar composition to fossil fuels through catalytic cracking method using alkaline heterogeneous catalyst. The catalytic cracking reaction was operated at batch reactor with a constant temperature of 370oC, a volume of 50 mL of feedstock, a pressure of 1 atm, and two kinds of catalysts: NaOH/-Al2O3 and KOH/-Al2O3 which has been characterization with X-ray diffraction and scanning electron microscopy. The best catalyst to produce biofuel type biogasoline (C5-C15) is KOH/-Al2O3 (5%) with a yield of 70% and selectivity to biogasoline of 74.46%. Meanwhile, the best catalyst to produce biofuel type biodiesel (C15-C22) is NaOH/-Al2O3 (5%) with a yield of 80% and selectivity to biodiesel of 67.72%.
