摘要： Disclosed is a doped cerium oxide sorbent that can effectively and regenerably remove H2S in the temperature range of about 500° C. to about 1000° C. Regenerable sorbents (e.g., ZnO, La2O3, CeO2) and methods of using them are disclosed that allow cyclic desulfurization from about 300-500° C., 350-450° C., and at about 400° C. In one embodiment, the present invention relates to a method of desulfurizing fuel gas comprising passing the fuel gas through the sorbent at a space velocity wherein the sulfur compounds are adsorbed substantially on the surface of the sorbent; and regenerating the sorbent by passing a regenerating gas through the sorbent, wherein substantially all of the sulfur compounds are desorbed from the sorbent surface. In a further embodiment, the method of desulfurizing fuel gas further comprises repeating the aforementioned steps while the fuel processor is in operation. In another embodiment, the step of passing the fuel gas may be preceded by reducing the sorbent by passing a reducing gas through the sorbent. In another embodiment, the sorbent may be fully sulfided, i.e., sulfided on its surface and bulk (internally).
