Title: Pyrochlore-type catalysts for the reforming of hydrocarbon fuels

Abstract

A method of catalytically reforming a reactant gas mixture using a pyrochlore catalyst material comprised of one or more pyrochlores having the composition A.sub.2-w-xA'.sub.wA''.sub.xB.sub.2-y-zB'.sub.yB''.sub.zO.sub.7-.DELTA.. Distribution of catalytically active metals throughout the structure at the B site creates an active and well dispersed metal locked into place in the crystal structure. This greatly reduces the metal sintering that typically occurs on supported catalysts used in reforming reactions, and reduces deactivation by sulfur and carbon. Further, oxygen mobility may also be enhanced by elemental exchange of promoters at sites in the pyrochlore. The pyrochlore catalyst material may be utilized in catalytic reforming reactions for the conversion of hydrocarbon fuels into synthesis gas (H.sub.2+CO) for fuel cells, among other uses.

Hydrocarbon fuel reforming catalyst and use thereof

Patent Ming, Qimin; Healey, Todd; Irving, Patricia Marie

The subject invention is a catalyst consisting of an oxide or mixed oxide support and bimetallic catalytically active compounds. The supporting oxide can be a single oxide, such as Al.sub.2O.sub.3; it also can be a mixture of oxides, such as Y.sub.2O.sub.3 stabilized ZrO.sub.2 (YSZ), Al.sub.2O.sub.3 with CeO.sub.2, Al.sub.2O.sub.3 with YSZ and others. The bimetallic compounds, acting as active components, are selected from platinum, and ruthenium, prepared in an appropriate ratio. The catalyst is used in the steam reforming of hydrocarbons to produce hydrogen for applications such as polymer electrolyte membrane fuel cells.

Noble metal catalysts and processes for reforming of methane and other hydrocarbons

Patent Marker, Terry L.; Linck, Martin B.; Wangerow, Jim; ...

Processes for converting methane and/or other hydrocarbons to synthesis gas (i.e., a gaseous mixture comprising H₂ and CO) are disclosed, in which at least a portion of the hydrocarbon(s) is reacted with CO₂. At least a second portion of the methane may be reacted with H₂O (steam), thereby improving overall thermodynamics of the process, in terms of reducing endothermicity (ΔH) and the required energy input, compared to “pure” dry reforming in which no H2O is present. Catalysts for such processes advantageously possess high activity and thereby can achieve significant levels of methane conversion at temperatures below those used conventionally undermore » « less

A hydrocarbon reforming catalyst material comprising a catalyst support impregnated with catalyst is provided for reforming hydrocarbon fuel gases in an electrochemical generator. Elongated electrochemical cells convert the fuel to electrical power in the presence of an oxidant, after which the spent fuel is recirculated and combined with a fresh hydrocarbon feed fuel forming the reformable gas mixture which is fed to a reforming chamber containing a reforming catalyst material, where the reforming catalyst material includes discrete passageways integrally formed along the length of the catalyst support in the direction of reformable gas flow.
