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.
