Abstract
There are disclosed catalyst formulations and methods for the preparation of oxygenated lower aliphatic compounds. The methods comprise applying a mixture of carbon monoxide and hydrogen to a catalyst formulation under reaction conditions, wherein the catalyst formulation is a solid which may comprise: an active metal, a mixed metal component comprising one or more of a metal A, a metal B, a metal C, and a promoter. In certain embodiments one or more of the metals and the promoter may be present as compounds. In a first embodiment the catalyst comprises a noble metal and an alkali metal promoter, mixed oxides of cerium, zirconium and molybdenum, and an alkali metal promoter. Carbon monoxide and hydrogen may be reacted in the presence of the catalysts disclosed to produce mixtures enriched in lower aliphatic alcohols and particularly ethanol. Various catalyst preparation methods are disclosed including autoignition and gel-sol methods.
