Abstract
A reducing gas useful for reducing ores containing carbon monoxide and hydrogen and low amounts of carbon dioxide and water vapor is produced by reacting gaseous and/or volatile liquid hydrocarbons with water vapor on an indirectly heated, nickel-containing catalyst under superatmospheric pressure. A partial amount of the hydrocarbons to be reacted is first cracked in contact with a nickel catalyst at 350.degree. - 500.degree.C. with at least part of the water vapor to form a hydrogen-containing gas, which is mixed with the remaining hydrocarbons. The mixture is further heated if desired and is then completely reacted at temperatures above 900.degree.C. in contact with the indirectly heated catalyst.
