The present disclosure relates generally to ceramic materials suitable for use as catalyst support materials, catalysts using such materials and methods for using them, such as methods for converting sugars, sugar alcohols, glycerol, and bio-renewable organic acids to commercially-valuable chemicals and intermediates. One aspect of the invention is a ceramic material including zirconium oxide and one or more metal oxides selected from nickel oxide, copper oxide, cobalt oxide, iron oxide and zinc oxide, the ceramic material being at least about 50 wt. % zirconium oxide. In certain embodiments, the ceramic material is substantially free of any binder, extrusion aid or additional stabilizing agent.

Method for the reduction of a sugar, sugar alcohol or glycerol

A hydrodeoxygenation catalyst comprises a metal catalyst, an acid promoter, and a support. The metal catalyst is selected from platinum, palladium, ruthenium, rhenium rhodium, osmium, iridium, nickel, cobalt, molybdenum, copper, tin, or mixtures thereof. The support is a promoted-zirconium material including texture promoters and acid promoters. The hydrodeoxygenation catalyst may be used for hydrodeoxygenation (HDO) of sugar or sugar alcohol in an aqueous solution. In one embodiment the HDO catalyst may be used for HDO of fatty acids such as fatty acid methyl esters (FAME), triglycerols (in plant oil and animal fat), pyrolysis oil, or lignin. The hydrodeoxygenation catalyst for fatty acid process does not require the use of an acid promoter, it is optional.

Hydrodeoxygenation catalyst

Ethylene glycol and propylene glycol may be made by hydrogenolysis of a polyol comprising the steps of reacting a polyol with hydrogen in the presence of a hydrogenolysis catalyst. The hydrogenolysis comprises nickel, one or more promoter, and one or more support. The promoter is selected from bismuth, silver, tin, antimony, gold, lead, thallium, cerium, lanthanum, and manganese. The support is selected from zirconia and carbon. A zirconia support comprises a zirconia textual promoter, which is selected from Cr, Mo, W, Nb, Ce, Ca, Mg, La, Pr, Nd, Al, and P. If the support comprises carbon, then the promoter is selected from bismuth and antimony. In another embodiment, if the support comprises carbon, then both the promoter is selected from bismuth and antimony, and the catalyst comprises copper. In another embodiment, the catalyst additionally comprises copper.

Catalyst for polyol hydrogenolysis

The present disclosure relates generally to catalyst support materials, catalysts and methods for using them, such as methods for converting sugars, sugar alcohols, glycerol, and bio-renewable organic acids to commercially-valuable chemicals and intermediates. One aspect of the invention is catalyst support material including ZrOand one or more oxides of manganese (MnO), the catalyst support material being at least about 50 wt % ZrOand MnO. In certain embodiments, the weight ratio of ZrOto MnOis within the range of about 1:1 to about 30:1; and/or the catalyst support material is substantially free of any binder, extrusion aid or additional stabilizing agent.
