Abstract
A catalyst for the conversion of synthesis gas comprising cobalt on a high surface area, high purity, low acidity alumina support of gamma-alumina, eta-alumina or mixtures thereof, whereby the catalyst is prepared by (A) impregnation of the alumina support with a non-aqueous, organic solvent impregnation solution of cobalt nitrate containing sufficient amounts of a Group IIIB or IVB metal salt to provide said catalyst with from about 0.05 to about 100 parts by weight of a Group IIIB or IVB metal oxide per 100 parts by weight cobalt, (B) reduction of the impregnated alumina support by heating, in the presence of hydrogen, at a heating rate of from about 0.5.degree. to about 5.degree. C. per minute to a maximum temperature in the range of 180.degree. to about 220.degree. C. for a hold time of 6 to about 24 hours and thereafter heating the impregnated alumina support in the presence of hydrogen while heating up to a maximum hold temperature of from about 250.degree. to about 400.degree. C. for a hold time of 6 to about 65 hours.
