Abstract: Disclosed herein is a metal oxide aerogel catalyst for hydrogenation and/or hydrodeoxygenation, a method for preparing the same, and a method for hydrogenation and/or hydrodeoxygenation using the same. The catalyst consists of a metal and an oxide thereof, and the catalyst is in a form of an aerogel produced by supercritical drying. The catalyst has an effect of providing high hydrogenation and/or hydrodeoxygenation efficiency of an oxygen-containing compound.

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.
