Abstract
The present invention relates to catalysts for the production of hydrogen using the water gas shift reaction and the carbon dioxide reforming of hydrocarbon-containing fuels. The catalysts nickel and/or copper on a ceria/zirconia support, where the support is prepared using a surfactant templating method. The invention also includes processes for producing hydrogen, reactors and hydrogen production systems utilizing these catalysts.
Claims79
A water gas shift reaction (WGSR) catalyst for the production of hydrogen from an input gas stream comprising H2O and carbon dioxide comprising a catalytically effective amount of nickel and/or copper, or an oxide thereof, dispersed on a support, wherein the support comprises a suitable mixed bi-metal oxide and the support is prepared using a surfactant templating method.
A carbon dioxide reforming (CDR) catalyst for the production of hydrogen from an input gas stream comprising a hydrocarbon fuel and carbon dioxide comprising a catalytically effective amount of nickel, or an oxide thereof, dispersed on a support, wherein the support comprises a suitable mixed bi-metal oxide and the support is prepared using a surfactant templating method.
A process for producing hydrogen, comprising:
- contacting a first input gas stream comprising a hydrocarbon fuel and carbon dioxide with a CDR catalyst between 550 and 700° C. to produce a first output stream comprising carbon monoxide and hydrogen, wherein the CDR catalyst comprises a catalytically effective amount of nickel, or an oxide thereof, dispersed on a support, wherein the support comprises a suitable mixed bi-metal oxide and the support is prepared using a surfactant templating method;
- and
- subsequently contacting the first output gas stream with a WGSR catalyst in the presence of H2O above 300° C. to produce a second output stream comprising carbon dioxide and hydrogen, comprises a catalytically effective amount of nickel and/or copper, or an oxide thereof, dispersed on a support, wherein the support comprises a suitable mixed bi-metal oxide and the support is prepared using a surfactant templating method.
