A Method To Prepare Catalyst For The Reduction Of Carbon Monoxide By Hydrogen
A method is suggested to prepare catalyst for the reduction of carbon monoxide by hydrogen to produce a mixture containing mainly C1-C4 hydrocarbons, consisting in the treatment of an iron and/or copper compound with hydrogen or a mixture of hydrogen with carbon monoxide. With the purpose to improve the catalyst selectivity, a complex salt of general formula
where M is iron or copper, x = 1-4, y = 1-3 is used as the iron and/or copper compound,
The treatment is carried out at a temperature of 315-385°C, pressure of 5-10 atm during 2-20 hr, hydrogen to carbon monoxide molar ratio is varied from 3:1 to 1:2.
