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.

Mixed alcohols production from syngas

A process for making alcohols comprising contacting a mixture of hydrogen and carbon monoxide with a catalyst comprising: (1) as a first component, at least one element selected from the group consisting of molybdenum and tungsten in free or combined form; (2) as a second component, at least one element selected from the group consisting of iron, cobalt and nickel in free or combined form; (3) as a third component, a promoter comprising an alkali or alkaline earth element in free or combined form; and optionally (4) as a fourth component, a support; to form an alcohol fraction boiling in the range of motor gasoline in at least 20 percent CO 2 free carbon selectivity.
