Sintesis Katalis NiMo/ZSM-5 dari Abu Sawit untuk Proses Catalytic Cracking Tandan Kosong Sawit (TKS) menjadi Bahan Bakar Cair

Abstract

Petroleum is unrenewable energy. Reducing dependence on petroleum, we needrenewable energy alternatives, one of which is bio-oil. Bio-oil can be obtainedby cracking catalyc biomass (especially palm empty fruit bunches) using acatalyst. The number of factory CPO (crude palm oil) in Indonesia generatesolid waste in the form of oil palm empty fruit bunches and palm ash (fly ash).Fly ash can be used in the manufacture of silica precipitation presipitasi.silikacan be used in the manufacture of ZSM-5. This research is a synthesis ofcatalysts for catalytic cracking NiMo/ZSM-5 palm empty fruit bunches intoliquid fuels. In this research, nickel molybdenum entrusted to the ZSM-5 (theratio / Al = 30, ratio = 7.4 N2O/Al2O3 by impregnation method and then producea solid product. Solids are dried at 120 0C for 2 hours, calcined at temperatures500 0C with time-varying calcination is 2.4 hours and 6 hours, oxidized at atemperature of 400 0C for 2 h, and reduced at a temperature of 400 0C for 2hours to obtain a catalyst and the ratio of NiMo/ZSM-5 with a total weight ofmetal by 5% by weight of the catalyst and the ratio of Nimo = 1/2. catalyst wasanalyzed by the BET method (Brunauer Emmett Teller) to determine thesourface area and catalytic performance test conducted by the catalytic crackingof palm empty fruit bunches into liquid fuels. derived liquid fuels characterizeddensity, viscosity and flash point. The results of the study, the largest surfacearea of the catalyst obtained by calcining time of 4 hours is 42.26 m2 / g and thelargest yield obtained using a catalyst with calcination time of 2 hours is 36.8%,yield known characterization density = 1.035 g / ml , viscosity = 10.48 cSt andflash point 51 0C. This yield belonging to the standard characterization of bio-oil
