Processes for hydrogenating alkanoic acids using catalyst comprising tungsten

摘要

A process hydrogenating alkanoic acids in the presence of a catalyst that comprises supports, one or more metals, tungsten oxide, and at least one alkaline earth metal oxide or metasilicate. The molar ratio of the at least one alkaline earth metal oxide or metasilicate to tungsten oxide, based on the metals, is from 1:3 to 5:1.
