TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The metal catalyst is transition metal catalyst and/or supported transition metal catalyst, preferably nickel, iron, cobalt and/or copper catalyst. The metal is nickel, iron, cobalt, copper, ruthenium, palladium, rhodium, osmium, iridium and/or rhenium, preferably nickel, iron, cobalt, ruthenium and/or copper. The solid acid catalyst is chosen from zeolite, silica-alumina, aluminum oxide, sulfated zirconia and mineral acid supported on oxide, preferably zeolite. The catalyst is a bifunctional solid comprising metal functionality and acid sites, preferably functional sites having acidic Bronsted and/or Lewis functionality.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The phenolic feed is contacted with metal catalyst and solid acid catalyst at autogenous pressure of 5-150 bar, preferably 5-60 bar, and at temperature of 50-300 degrees C, preferably 80-240 degrees C for 0.01 seconds to 8 hours, preferably 0.25 seconds to 4 hours. The oxidized hydrogen donor produced in the hydrotreatment process is separated from the reaction mixture, transferred to a secondary reactor, contacted with molecular hydrogen in the presence of hydrogenation catalyst, and regenerated donor transferred to primary reactor. Preferred Composition: The hydrogen donor is chosen from 3-8C secondary alcohol, 3-10C cyclic alkene, 2-9C polyol, saccharide and/or formic acid. The hydrotreatment is carried out solvent-free or in the presence of a solvent chosen from hydrocarbon, supercritical carbon dioxide, water, aliphatic ether, cyclic ether, ester and fluorinated solvent. The ratio of the reaction products is controlled by adjusting the molar ratio of phenolic content to the donor, or by adjusting the ratio of metal catalyst to solid acid catalyst. The hydrotreatment is carried out in one or more intervals at respective reaction conditions differing in temperature and/or pressure.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The phenolic feed is chosen from lignin, phenolics derived from lignocellulosic materials chosen from wood, switchgrass, sugarcane bagasse and crop residues, and bio-oil obtained by pyrolysis of lignocellulosic material. The phenolic feeds are derived from liquefaction of phenolic resin and from the Kraft lignin and lignosulfonate.
