摘要: Rh-substituted pyrochlores have been shown to be excellent diesel reforming catalysts. However, it is desirable reduce the amount of this expensive material while maintaining an acceptable level hydrogen production. This study demonstrates that a segmented catalyst bed approach can used achieve objective. Two strategies were examined: (1) promotion indirect mechanism with combustion in reactor inlet, followed by catalyst, and (2) placement catalysts regions conditions which they are less likely deactivate. The first demonstrated Ni-substituted barium hexaaluminate inlet promote pyrochlore outlet, but should fill than 50% reactor. second showed benefit use sulfur-tolerant noble metal outlet significant portion of...
