Claim 12:
13. A multi-zone reforming catalyst, comprising:
a first support structure;
first Ni-containing catalyst having reforming activity;
a first metal oxide support layer that is thermally phase stable at 800° C. to 1600° C. comprising stabilized zirconia, perovskite, pyrochlore, spinel, hibonite, zeolite, an oxide selected from the group consisting of α-Al2O3, LaAlO3, LaAl11O18, MgO, CaO, ZrO2, TiO2, CeO2, Y2O3, La2O3, SiO2, Na2O, K2O, and mixtures thereof, or a combination thereof,
the first catalyst and the first metal oxide support layer comprising a first catalyst system supported by one or more surfaces of the first support structure, the first catalyst system comprising 0.5 wt % or more of a combined weight of the first catalyst system and the first support structure;
a second support structure;
a second catalyst having reforming activity comprising Ni, Rh, Ru, Pd, Pt, Cu, Ir, or a combination thereof; and
a second metal oxide support layer comprising stabilized zirconia, perovskite, pyrochlore, spinel, hibonite, zeolite, an oxide selected from the group consisting of α-Al2O3, LaAlO3, LaAl11O18, MgO, CaO, ZrO2, TiO2, CeO2, Y2O3, La2O3, SiO2, Na2O, K2O, and mixtures thereof, or a combination thereof, the second catalyst and the second metal oxide support layer comprising a second catalyst system, the second catalyst system being different than the first catalyst system, the second catalyst system being supported by one or more surfaces of the second support structure.
