Abstract
A method of fuel gas desulfurization comprises the steps of introducing fuel, such as coal, into a gasifier, heating the fuel in the gasifier to a temperature so as to form a gaseous fuel mixture containing sulfur compounds, and conveying the gaseous fuel mixture over a sulfur absorbing and surface-catalyzing zinc-based sorbent that catalyzes an exothermic reaction to locally increase the surface temperature of the sorbents, thereby enhancing the rate of desulfurization. Additionally, in accordance with the instant invention, the sulfur absorbing and surface-catalyzing zinc-based sorbent comprises a chemical composition of a metal selected from the group consisting of iron, cobalt, and molybdenum that catalyzes an exothermic reaction at the sorbent surface and an inert metal selected from the group consisting of titanium, zirconium, cerium and hafnium for desulfurization.
