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.
