    Abstract: A method of hydrothermal hydrocatalytic treating biomass is provided. Lignocellulosic biomass solids is provided to a hydrothermal digestion unit in the presence of a digestive solvent, at least one of ammonia or a source of ammonia, and a supported hydrogenolysis catalyst containing (a) sulfur, (b) Mo or W, and (c) Co, Ni or mixture thereof, incorporated into a suitable support. The lignocellulosic biomass solids and digestive solvent are heated in the presence of hydrogen, supported hydrogenolysis catalyst and the at least one of ammonia or a source of ammonia forming a product solution containing plurality of oxygenated hydrocarbons and ammonia. At least a portion of ammonia is separated and recycled to the hydrothermal digestion unit.

    Abstract: The present invention relates to a process for hydrogenating an aldehyde. An aldehyde is contacted with a catalyst comprising a support containing at least 95% a-alumina and non-support metals dispersed on the surface of the support. The non-support metals comprise nickel and/or one or more compounds thereof and molybdenum and/or one or more compounds thereof. The nickel and/or one or more compounds thereof comprise from 3 wt.% to 9 wt.% of the catalyst, by metallic weight, and the molybdenum and/or one or more compounds thereof comprise from 1 wt.% to 4 wt.% of the catalyst, by metallic weight.
