| Summary: | Catalitic cracking of palm oil using the mixture of H-MCM-41 and Ni/MCM-41 pellets as catalyst has been performed. MCM-41 was started from the dissolution of CTAB, then added TMAOH and K2SO4 were added to improve the stability of the material. Crystalization process was done by adding of sodium silicate and sodium aluminate into the solution, and then 50% H2SO4 was added to decrease pH of the solution. Further that the hydrothermal process was done at 90 oC for 36 h, and then washed, dried, and calcined at 540 oC. A synthesized MCM-41 was characterized using XRD, FTIR, BET, and TEM. H-MCM-41 catalyst was obtained by soaking the MCM-41 into 0,5 M NH4Cl solution and then calcined. The Ni/MCM-41 was obtained by soaking the MCM-41 into 0,1 M NiCl2 solution then after drying it was reduced at 450 oC. In the cracking process, ratio of H-MCM-4: Ni/MCM-41 = 1:1, 1:3, 3:1,1:0 and 0:1 were used. Ratio of the catalyst of 3:1 produced the highest oil conversion, and this ratio was used to form a pellet catalyst. The catalytic cracking processes using the pellet resulted conversion value of 70.40% containing 12.77% of OLP with selectivity to biofuel of 3.48%. The biofuel analyses of GC resulted the gasoline like fractions of 21.66 %, kerosene like fraction of 64.39 %, and 13.95 % diesel like fractions
