Catalyst for the production of ethanol by hydrogenation of acetic acid comprising platinum -tin on silicaceous support

摘要

A process for selective formation of ethanol from acetic acid includes contacting a feed stream containing acetic acid and hydrogen at an elevated temperature with catalyst comprising platinum and tin on a high surface area silica promoted with calcium metasilicate. Selectivities to ethanol of over 85% are achieved at 280C with catalyst life in the hundreds of hours.
