Abstract
A process for hydrogenating feeds into their corresponding alcohols by contact with a coprecipitated catalyst comprising copper, aluminum, and a metal (X) selected from the group consisting of magnesium, zinc, titanium, zirconium, tin, nickel, cobalt and mixtures thereof; that has been reduced with an increasing temperature during the reduction.
Claims1
A reduced catalyst composition comprising copper, aluminum, and a metal, X, selected from the group consisting of magnesium, zinc, titanium, and mixtures thereof;
- made by a process comprising:
- reducing a mixture of the oxides of copper, aluminum, and X by heating in the presence of a reducing gas under activating conditions which comprise gradually increasing the temperature from an ititial temperature of about 50.degree. C. to a final temperature of about 180.degree. C. at a rate of about 3.degree. C. to about 6.degree. C. per hour.
