Synthesis gas to alcohols process
This patent describes a method of preparing a mixture of lower aliphatic alcohols which comprises reacting carbon monoxide and hydrogen in the presence of a sulfide-containing heavy metal catalyst under carbon monoxide-hydrogenation conditions. The catalyst consists of: (1) at least one sulfided heavy metal element selected from the group consisting of molybdenum; tungsten, and rhenium, (2) a sulfided heavy metal element form the group consisting of cobalt, iron, and nickel, (3) a promoter comprising an alkali or alkaline earth element in free or combined form, and optionally, (4) a support, the improvement which comprises improving the selectivity to the alcohols by treating the sulfided heavy metal elements with a nitrogen-containing base prior to treatment with the promoter, the nitrogen-containing base being selected from the group consisting of urea, dimethylolurea, cyanuric acid, melamine, melam, melem, and melon.
