A process for reducing free oxygen in a gaseous nitrogen stream includes the steps of (i) reforming a hydrocarbon to generate a gas mixture containing hydrogen and carbon oxides, (ii) mixing the gas mixture with a nitrogen stream containing free oxygen, and (iii) passing the resulting nitrogen gas mixture over a conversion catalyst that converts at least a portion of the free oxygen present in the nitrogen to steam wherein the hydrocarbon reforming step includes oxidation of a hydrocarbon using an oxygen-containing gas.

Methods and apparatus for producing hydrogen with reforming catalysts. The reforming catalysts may be platinum group metals on a support material, and they may be located in a reforming reaction zone of a primary reactor. The support material may be an oxidic support having a ceria and zirconia promoter, or may include a neodymium stabilizer. The support material may also include at least one Group IA, Group IIA, manganese, or iron metal promoter. The primary reactor may have a first and second reforming reaction zones, where upstream catalysts located in the first reforming reaction zone and downstream catalysts located in the second reforming reaction zone may be selected to perform optimally under the conditions in their respective reforming reaction zone.

Methods, apparatus, and systems for producing hydrogen from a fuel

Methods and apparatus for producing hydrogen are provided. The methods and apparatus utilize reforming catalysts in order to produce hydrogen gas. The reforming catalysts may be platinum group metals on a support material, and they may be located in a reforming reaction zone of a primary reactor. The support material may an oxidic support having a ceria zirconia promoter. The support material may be an oxidic support and a neodymium stabilizer. The support material may also be an oxidic support material and at least one Group IA, Group IIA, manganese, or iron metal promoter. The primary reactor may have a first and second reforming reaction zones. Upstream reforming catalysts located in the first reforming reaction zone may be selected to perform optimally under the conditions in the first reforming reaction zone. Downstream reforming catalysts located in the second reforming reaction zone may be selected to perform optimally under the conditions in the second reforming reaction zone.

Carbonaceous material is removed from a catalyst within an autothermal reformer by introducing an isolated oxidant stream into the autothermal reformer prior to introduction of hydrocarbon fuel into the reformer. A hydrocarbon stream is introduced into the autothermal reformer following removal of the carbonaceous material. A concurrent supply of the hydrocarbon stream and the oxidant stream to the autothermal reformer is maintained such that an exothermic reaction driven by the oxidant stream provides heat to an endothermic reaction driven by water vapor in the hydrocarbon stream. In accordance with 37 CFR 1.72(), the purpose of this abstract is to enable the United States Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract will not be used for interpreting the scope of the claims.
