Abstract
The present invention provides catalysts, methods, and reactor systems for converting oxygenated hydrocarbons to oxygenated compounds. The invention includes methods for producing cyclic ethers, monooxygenates, dioxygenates, ketones, aldehydes, carboxylic acids, and alcohols from oxygenated hydrocarbons, such as carbohydrates, sugars, sugar alcohols, sugar degradation products, and the like, using catalysts containing palladium, molybdenum, tin, and tungsten. The oxygenated compounds produced are useful in the production of liquid fuels, chemicals, and other products.
Claims20
A heterogeneous catalyst, the heterogeneous catalyst comprising (i) a Group VIII metal, (ii) a member selected from the group consisting of molybdenum, tungsten, tin, and combinations thereof, and (iii) a metal oxide support,
- wherein the heterogeneous catalyst is configured to produce a monooxygenated cyclic ether and/or a monooxygenated cyclic ketone when an aqueous oxygenated hydrocarbon feedstock solution, the aqueous feedstock solution comprising water and an oxygenated hydrocarbon selected from the group consisting of a starch, a sugar, a sugar alcohol, a polysaccharide, an oligosaccharide, a trisaccharide, a disaccharide, a monosaccharide, and combinations thereof, and hydrogen are contacted with the heterogeneous catalyst.
