A method for the desulfurization of sour natural gas containing sulfur contaminants wherein the natural gas is first heated to a temperature in the range of 250.degree. C. to 450.degree. C. and then contacted with a bed of sponge iron to remove at least a portion of the sulfur contaminants to form a sweet natural gas.

Method for the desulfurization of hydrocarbon gas

A method is disclosed for achieving improved reduction efficiency and economy in the reduction of particulate metal ores, e.g. iron ore, in a vertical shaft, moving bed reactor having a reduction zone in which a heated reducing gas is caused to flow through a portion of the ore bed to reduce the metal ore thereof to metal; e.g. sponge iron. The improved efficiency and economy is achieved through an integrated reduction system in which a conventional reformer is used without the need to upgrade the reformed gas prior to feeding it directly to the reduction reactor as a reducing gas.
