Multi-layered catalyst for autothermal steam reforming of hydrocarbons and its use
DRIVE
March 3, 2004
Catalyst comprises a multilayered catalyst composition (2) applied onto a support body (1) and consisting of a lower catalyst layer (3) directly lying on the support body and an upper catalyst layer (4) lying on the lower catalyst layer. The lower catalyst layer catalyzes preferably partial oxidation and the upper catalyst layer preferably steam reforming. Independent claims are also included for the following: (1) process for autothermal catalytic steam reforming of hydrocarbons; and (2) reformer containing the above catalyst for catalytic steam reforming of hydrocarbons to produce hydrogen for fuel cell systems. Preferred Features: The lower catalyst layer contains 0.1-5 wt.% platinum and the upper catalyst layer contains 0.1-5 wt.% rhodium, referred to their total weight. The catalyst layers contain precious metals, rare earth metals, and base metals of the subgroups as further catalytically active components.
