Various type of Zinc (3.25 %) Mo (6.34 %) Hz catalysts have been prepared using incipient wetness impregnation method. The catalysts were characterized by X-ray diffraction (XRD), energy dispersive analysis x-ray (EDAX) and Brunauer-Emmett-Teller (BET) method. The performance of the catalysts, Zinc (3.25 %) Mo (6.34 %) Hz was investigated for the catalytic hydrocracking of Kapook seed oil (KSO) to hydrocarbon biofuel in a slurry pressure batch reactor system with a stirrer. The hydrocracking reaction was carried out at reaction temperatures from 300-400 °C and reactor pressure of 15 bar for 2 h under H2 flowing. The effect of reaction temperature on composition of hydrocarbon compounds, n-paraffin, conversion and selectivity in liquid products was studied with a variation of ZincMoHz catalysts. It showed the highest hydrocarbon content decarboxylation and/or decarbonylation were 18.61 area% of n-paraffin and the highest content for gasoil-range alkanes was 10.44 area% obtained at 400 °C. The result show that the Zinc (3.25%) Mo (6.34%) Hz catalyst activity was found that the gasoil fraction which triglycerides where cracked with long carbon double bonds chains over Zinc (3.25%) Mo (6.34%) Hz catalyst.
