摘要： A process for converting a sugar, sugar alcohol, or glycerol to a valuable chemical is described. The process may use a support comprising zirconium oxide promoted by a polyacid or promoter material. A catalytically active metal may be impregnated on the polyacid-promoted zirconium oxide support and the catalyst may then be introduced the sugar, sugar alcohol, or glycerol a source of hydrogen under reaction conditions. At least 40 wt % of the sugar, sugar alcohol or glycerol may be converted to a polyol and/or a shorter carbon-chain alcohol that may include at least one of propylene glycol, ethylene glycol, glycerin, methanol, ethanol, propanol and butandiols. Specific processes for converting glycerin having a selectivity for propylene glycol and for converting sorbitol with a selectivity for propylene glycol, ethylene glycol, and/or glycerin are also described.

摘要： A polyacid-promoted, zirconia catalyst or catalyst support having a high crush strength, surface area and pore volume is described. The polyacid-promoted, zirconia catalyst or catalyst support may be made by combining a zirconium compound with a polyacid/promoter material that includes the group 6 metals (i.e., chromium (Cr), molybdenum (Mo), tungsten (W)), as well as phosphoric acids, sulfuric acids, and polyorganic acids. The zirconyl-promoter precursor may be extruded in the absence of any binder or extrusion aid. The polyacid-promoted, zirconia catalyst or catalyst support is hydrothermally stable in aqueous phase hydrogenation or hydrogenoloysis reactions.
