Base-modified zeolite-containing catalysts for the conversion of synthesis gas to alcohols

Patent ·
OSTI ID:5857542
; ;

This patent describes a zeolite-containing heavy metal oxide catalyst for preparing lower aliphatic alcohols which comprises reacting carbon monoxide and hydrogen under carbon monoxide-hydrogenation conditions, the catalyst comprising: a zeolite support consisting of a member selected from the group consisting of Y zeolite, X zeolite, aluminophosphate, ZSM-5, ZSM-11, silicalite, zeolite A and mordenite; at least one heavy metal oxide selected from the group consisting of molybdenum oxide, tungsten oxide and rhenium oxide; optionally a heavy metal oxide from the group of elements consisting of cobalt oxide, iron oxide and nickel oxide; and a promoter comprising an alkali or alkaline earth element in free or combined form. The improvement consists of improving the selectivity to the alcohols by treating the zeolite support with a nitrogen-containing base selected from the group consisting of urea, dimetholurea, cyanuric acid, melamine, melan, melem and melon.
