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.

Abstract: Disclosed are a method for producing lactic acid from wastes containing cellulose and/or hemicellulose and a catalyst for thermochemical conversion reaction of wastes containing cellulose and/or hemicellulose. The method includes a step of adding a metal catalyst to wastes containing cellulose and/or hemicellulose and performing thermochemical conversion reaction. The method provides an effect of producing lactic acid from discarded wastes, e.g., waste paper such as waste corrugated paperboards, waste paper boxes, waste newspapers, etc.
