Abstract
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.
