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.
