Base-modified metal oxide catalysts for the conversion of synthesis gas to alcohols

Patent ·
OSTI ID:6001226
;

A method is described for preparing lower aliphatic alcohols where carbon monoxide and hydrogen are reacted in the presence of an oxide-containing heavy metal catalyst under carbon monoxide-hydrogenation conditions. The catalyst comprises: (1) a support consisting of a member selected from the group consisting of alumina, silica, titania, zirconia, lanthana and mixed metal oxides thereof: (2) at least one metal oxide selected from the group consisting of molybdenum oxide, tungsten oxide, and rhenium oxide; (3) a heavy metal oxide selected from the group of elements consisting of cobalt oxide, iron oxide and nickel oxide; and (4) a promoter comprising an alkali or alkaline earth element in free or combined form. The improvement comprises improving the selectivity to the alcohols by treating the metal oxide or oxides with a nitrogen-containing compound selected from the group consisting of urea, dimethyl-olurea, cyanuric acid, melamine, melam, melen and melon, or a thermally stable derivative thereof.
