In this study, the thermo-catalytic hydrogenation using corn stark and wasted palm kernel shell was carried out for the production of hydrocarbon compounds in direct biomass liquefaction. The conversion of biomass in direct biomass liquefaction over Mo-based catalyst increased with increasing the reaction temperature and the content of the volatile matter contained in biomass and the corn starch was more available than the wasted palm kernel shell. And then, the conversion was about 97.9% using corn starch and was about 92.4% using wasted palm kernel shell at 400oC. It was confirmed that the liquefied products obtained after the thermo-catalytic reaction were C6, C7, C8-typed hydrocarbon compounds.
