Catalyst for hydrogenation of carbonyl compound and alcohol production method

Provided is a catalyst including a metal component including a first component that is rhenium and one or more second components selected from the group consisting of silicon, gallium, germanium, and indium and a carrier on which the metal component is supported, the carrier including an oxide of a metal belonging to Group 4 of the periodic table. Also provided is an alcohol production method in which a carbonyl compound is treated using the above catalyst. It is possible to produce an alcohol by a hydrogenation reaction of a carbonyl compound with high selectivity and high efficiency while reducing side reactions.

CATALYSTS AND PROCESSES FOR THE DIRECT PRODUCTION OF LIQUID FUELS FROM CARBON DIOXIDE AND HYDROGEN

Embodiments of the present invention relates to two improved catalysts and associated processes that directly converts carbon dioxide and hydrogen to liquid fuels. The catalytic converter is comprised of two catalysts in series that are operated at the same pressures to directly produce synthetic liquid fuels or synthetic natural gas. The carbon conversion efficiency for CO.sub.2 to liquid fuels is greater than 45%. The fuel is distilled into a premium diesel fuels (approximately 70 volume %) and naphtha (approximately 30 volume %) which are used directly as “drop-in” fuels without requiring any further processing. Any light hydrocarbons that are present with the carbon dioxide are also converted directly to fuels. This process is directly applicable to the conversion of CO.sub.2 collected from ethanol plants, cement plants, power plants, biogas, carbon dioxide/hydrocarbon mixtures from secondary oil recovery, and other carbon dioxide/hydrocarbon streams. The catalyst system is durable, efficient and maintains a relatively constant level of fuel productivity over long periods of time without requiring re-activation or replacement.
