Abstract:
Bioenergy is new and renewable alternative energy which is currently developed enthusiastically. Bioenergy could be
produced by catalytic cracking method, which is cracking carbon chain to raise energy fraction. This paper observes potential
non-food bioenergy of cashew nut shell liquid as an alternative bioenergy source using catalytic cracking method. The effect
of impregnated-metals Nikel and Molibdenum catalyst used in hydrocracking of Cashew Nut Shell Liquid (CNSL) into
bioenergy was investigated. It focused specifically on two type of natural activated zeolite catalysts: NiO and NiOMoO at
o temperature reaction of 450 C and ratio feed catalyst of 2 and 4. Catalysts characterization was conducted according to a
gravimetric method to determine acidity of catalyst; Spectroscopy FT-IR analysis to get distribution of active site catalyst;
X-Ray Diffraction (XRD) analysis to observe crystalinity of catalyst; and Gas Sorption Analyzer (GSA) to measure
surface area, porosity and total of pore volume. Bioenergy of CNSL in the liquid-phase, which were predominantly by
gasoline, diesel oil, and heavy oil, was further analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) to
determine the compound energy fraction qualitatively and quantitatively. The result showed that the NiOMoO (natural
activated zeolite) provided an optimal performance with liquid product conversion was about 65-75%, and selectivity
gasoline as well as diesel fraction was about 37-47% and 22-31%, respectively.
