ABSTRACT:
Sulfur and sulfur compounds are removed from a gas stream, such as a hydrocarbon fuel gas stream so as to render the gas stream suitable for use in a fuel cell power plant. Natural gas and recycled hydrogen enters the hydrodesulfurizer assembly at a temperature of about 120.degree. F. The gas stream is heated to a temperature of about 625.degree. F. whereupon it enters a desulfurizing bed formed from a mixture of platinum catalyst deposited on alumina pellets, and a pelletized zinc oxide hydrogen sulfide absorbent. The gas is cooled to an exit temperature of about 525.degree.F. as it passes through the desulfurizer bed. The desulfurizer bed is combined with a shift converter which reduces carbon monoxide in the desulfurized gas stream after the latter has passed through a steam reformer bed.
