Abstract

Ni and Mo doped on the ZSM-5 catalyst has been prepared. In this study the effect of metal concentration on the character of the catalyst was determined by varying the concentration of Ni and Mo by 1 to 5% (wt) against the ZSM-5 using impregnation method. The characterization results show that the catalyst contains Ni by 4%, while Mo was 5%, on the other hand, Mo was more dispersed in ZSM-5 particles compared to Ni. The total acidity for Mo-ZSM-5 catalysts was higher than Ni-ZSM-5. The surface area of ZSM-5 after loading by Ni and Mo decreased significantly, but the pore size increased slightly. Meanwhile the pore volume for the Ni-ZSM-5 was relatively the same as the pore volume of the ZSM-5 but the Mo-ZSM-5 was reduced by about 20%.
