Claim 21:
22. A method for reforming hydrocarbons in a cyclic reaction environment, comprising:
reacting a mixture comprising fuel and 0.1 vol % or more of O2 under combustion conditions in a combustion zone within a reactor to heat one or more surfaces of a monolith in a reaction zone to a regenerated surface temperature of 800° C. or more, the reaction zone comprising a catalyst system supported on the one or more surfaces of the monolith;
exposing a reactant stream comprising a reformable hydrocarbon to the one or more surfaces in the reaction zone to increase the temperature of the reactant stream; and
exposing the reactant stream to the catalyst system in the reaction zone at a temperature of 800° C. or more to form a product stream comprising Hz, a direction of flow for the reactant stream within the reaction zone being reversed relative to a direction of flow for the mixture,
wherein the catalyst system comprises a catalyst and a metal oxide support layer, the metal oxide support layer being thermally phase stable at 800° C. to 1600° C., the catalyst system comprising NiAl2O4, the catalyst system comprising 0.5 wt % or more of a combined weight of the catalyst system and the monolith.
