A multi-stage UCSRP process and system for removal of sulfur from a gaseous stream in which the gaseous stream, which contains a first amount of HS, is provided to a first stage UCSRP reactor vessel operating in an excess SOmode at a first amount of SO, producing an effluent gas having a reduced amount of SO, and in which the effluent gas is provided to a second stage UCSRP reactor vessel operating in an excess HS mode, producing a product gas having an amount of HS less than said first amount of HS.

Process and system for removing sulfur from sulfur-containing gaseous streams

A fuel processing system for heavier sulfur-laden hydrocarbon fuels, such as JP-8 and diesel fuels, having a fuel processor in which the sulfur-laden hydrocarbon fuels are reformed using steam reforming, an integrated desulfurization/methanation unit, and a solid oxide fuel cell. The heart of the system is the desulfurization/methanation unit which has a first reactor vessel and a second reactor vessel disposed within the first reactor vessel, forming an enclosed reaction space between the first reactor vessel and the second reactor vessel. A methanation catalyst is provided in the enclosed reaction space or the second reactor vessel. A desulfurization material is provided in the other of the enclosed reaction space and the second reactor vessel. During the normal course of operation, the desulfurization material will reach a saturation point at which it is no longer able to adsorb the sulfur-containing compounds. Contrary to conventional systems in which a fuel containing sulfur is desulfurized prior to methanation in two separate desulfurizer and methanation vessels and the spent desulfurization material is regenerated, the first and second reactor vessels of this invention are separable such that the reactor vessel containing the spent desulfurization material simply can be removed and replaced with a reactor vessel containing fresh desulfurization material.

JP-8 fuel processor system

A fuel processor for producing a hydrogen-rich product gas suitable for direct use in fuel cell applications includes a housing, an annular shift/methanator reactor vessel at least one reactor vessel wall disposed within the housing and forming an outer annular space between the at least one reactor vessel wall and the housing. A combustion chamber having at least one combustion chamber wall and forming a first inner annular space between the at least one combustion chamber wall and the at least one reactor vessel wall is disposed in the interior space formed by the annular shift/methanator reactor vessel, and a reformer reactor vessel having at least one reformer vessel wall and forming a second inner annular space between the at least one reformer vessel wall and the at least one combustion chamber wall is disposed within the combustion chamber.
