Abstract: Disclosed herein are a catalyst for hydrocracking reaction of high molecular weight components in bio-oil, a method for preparing the same and a method for bio-oil upgrading using the same. The catalyst includes a zeolite carrier; and at least one metal selected from the group consisting of nickel (Ni), ruthenium (Ru) and cerium (Ce) supported on the carrier. The catalyst promotes the hydrocracking of high molecular weight compounds contained in the bio-oil, but also inhibits the polymerization reaction of the decomposed product, thereby more effectively enhancing the hydrocracking reaction of the bio-oil.

Abstract: Disclosed herein is a catalyst for an upgrading reaction of biomass pyrolysis oil, a method for preparing the same, and a method for upgrading biomass pyrolysis oil using the same. The catalyst is a composite inorganic oxide, and the composite inorganic oxide includes lanthanum, nickel, titanium, and cerium. When a metal catalyst supported on carbon is used as a catalyst for a first step reaction, by using the catalyst as a catalyst for a second step reaction, the efficiency of the upgrading reaction of bio-oil is increased and a continuous reaction is possible without clogging of a continuous reactor.
