Abstract
The present invention relates to the vapour phase hydrogenation of carboxylic acid esters to give alcohols. More particularly, this invention pertains to a process for the production of an alcohol by hydrogenation of an ester with a hydrogenation catalyst comprising a Group VIII element, a promoter, and a carbon support. This process is characterized in that (1) the Group VIII element is ruthenium, nickel, or rhodium, (2) the promoter is introduced on to the carbon as a water stable compound of Group IA, IIA metal, a lanthanide or actinide, and (3) the carbon has a BET surface area of at least 100 m.sup.2 /g, and a ratio of BET to basal plane surface area not greater than 4:1, and (4) the hydrogenation is carried out in the vapor phase at a temperature in the range 100.degree. C. to 400.degree. C. at a total space velocity of 100 to 120,000.
