Promoters for Cobalt-Tin Catalysts for Reducing Alkanoic Acids

摘要

The present invention relates to a process for the formation of an alcohol from an alkanoic acid, the steps of the process comprising: contacting a feed stream containing the alkanoic acid and hydrogen at an elevated temperature with a hydrogenating catalyst comprising from 3 to 25 wt. % of active metals comprising tin and cobalt and a metal promoter selected from the group consisting of noble metals or first metal, the first metal selected from the group of barium, cesium and potassium.
