Abstract: Provided is a method for producing a high-carbon number saturated hydrocarbon compound by subjecting a mixed biomass solution containing benzyl phenyl ether (C6H5CH2OC6H5) to a two-step reaction process using a difunctional catalyst having an acid catalyst combined with a metal catalyst. The method allows development of a fuel substituting for and supplementing petroleum through decomposition and conversion of a biomass containing lignin or the like, thereby providing a non-petroleum based biofuel.

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.
