Abstract
Acetic acid is hydrogenation in the presence of a catalyst comprising one or more active metals on a silica support, wherein the catalyst has a radial crush strength of at least 4 N/mm. The one or more active metals may include cobalt, copper, gold, iron, nickel, palladium, platinum, iridium, osmium, rhenium, rhodium, ruthenium, tin, zinc, lanthanum, cerium, manganese, chromium, vanadium, molybdenum and mixtures thereof. Radial crush strength may be improved by steam treating the catalyst support prior to the loading of the one or more active metals.
