US Patent:

48310603, May 16, 1989

Filed:

Jun 6, 1988

Appl. No.:

7/202754

Inventors:

Rex R. Stevens - Midland MI
Mark M. Conway - Sanford MI

Assignee:

The Dow Chemical Company - Midland MI

International Classification:

C07L 2706

US Classification:

518714

Abstract:

Mixed alcohols are produced from carbon monoxide and hydrogen gases using an easily prepared catalyst/co-catalyst metal catalyst. The catalyst metals are molybdenum, tungsten or rhenium. The co-catalyst metals are cobalt, nickel or iron. The catalyst is promoted with a Fischer-Tropsch promoter like an alkali or alkaline earth series metal or a smaller amount of thorium and is further treated by sulfiding. The composition of the mixed alcohols fraction can be selected by selecting the extent of intimate contact among the catalytic components.
