A method to separate carbon monoxide from a gas obtained from a fuel reformer containing hydrogen and carbon monoxide is outlined. Reformer gas containing carbon monoxide is subjected to a steam shift reaction to produce additional hydrogen and reduce carbon monoxide to form carbon dioxide. Mingling the resulting gas in an alcohol capable of dissolving carbon monoxide forms a gas containing hydrogen substantially devoid of carbon monoxide. The alcohol containing dissolved carbon monoxide is then recycled to the reformer to repeat the method. The gas, substantially free of carbon monoxide containing carbon dioxide, is subjected to a solution capable of substantially removing carbon monoxide from the gas by scrubbing. The solution containing dissolved carbon dioxide is heated to produce gaseous carbon dioxide and a solution, for recycling toward additional scrubbing. The resulting gas is subjected to a medium for scrubbing the gas as a means for purification. The gas containing hydrogen, substantially devoid of carbon monoxide, will provide significantly purified hydrogen without employing a membrane. The medium employed for scrubbing, containing volatile components from the gas, is then heated to produce vapor and a medium to be recycled for additional scrubbing. The resulting vapor is combined with reformer gas and accordingly recycled.
