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.

1. A process for formation of ethanol from acetic acid comprising: contacting a feed stream containing acetic acid and hydrogen at an elevated temperature with a hydrogenating catalyst comprising from 3 to 25 wt. % of active metals and 0.05 to 2 wt. % of a promoter on a support, wherein the active metals comprise cobalt and tin, and wherein the promoter is selected from the group consisting of a first metal and a noble metal.
