Process for the production of alcohol from a carbonaceous feedstock

摘要

Process for the conversion of ethanoic acid into ethanol by (a) introducing ethanoic acid and H2 into a primary hydrogenation unit in the presence of a precious metal-based catalyst to produce ethanol and ethyl ethanoate and (b) introducing ethyl ethanoate, from step (a), together with H2 into a secondary hydrogenation unit in the presence of a copper-based catalyst to produce ethanol. Ethanol from step (b) is recovered.
