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.
