Abstract
Gas desulfurization sorbents and methods using them for removal of sulfur from gas streams, particularly at high temperatures ranging from 500 to 1000° C. The sorbents and methods are of particular application to produce a sulfur-clean feed from reformate gas generated from readily available transportation fuels containing sulfur. Sorbents of the invention can reduce the sulfur concentration in reformate gas to parts per billion on volume basis (ppbv) levels over a large range of temperatures. Sorbent materials of this invention comprise a nickel phase dispersed on a particulate support or a monolith support. The support can be a high surface area support with surface area of 100 m/g or higher. The invention also provides systems for desulfurizing reformate gas and systems for providing a desulfurized gas to a fuel cell, particularly a solid oxide fuel cell.
