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.
