Fuel Production from LDPE Plastic Waste over Natural Zeolite Supported Ni, Ni-Mo, Co and Co-Mo Metals

Hydrocracking of LDPE plastics into fuel over bi-functional catalysts was systematically studied. The natural zeolite from Sukabumi, Indonesia was refluxed in HCl 6N for 30 minutes and dried in an oven, then the activated natural zeolite (Z) was produced. This study found that natural zeolite obtained from Sukabumi which consists of the mordenite type crystalline. For bifunctional catalysts, Ni, Ni-Mo, Co and Co-Mo metals were loaded into the activated natural zeolite respectively to increase the activity and selectivity for hydrocracking process. The catalyst samples were heated in a microwave and done the reduction by hydrogen gas stream, produced Ni/Z, Ni-Mo/Z, Co/Z and Co-Mo/Z. Hydrocracking process was carried out effectively at 350 &de
