Claim 5:
6. A method for reforming hydrocarbons in a cyclic reaction environment, comprising:
reacting a mixture comprising fuel and 0.1 vol % O2 or more under combustion conditions in a combustion zone within a reactor to heat one or more surfaces in a reaction zone to a regenerated surface temperature of 1100° C. or more, the mixture of fuel and O2 comprising 120% or more of a stoichiometric molar amount of O2 for combustion of the fuel, the reaction zone comprising a catalyst system supported on one or more surfaces of a support structure, the catalyst system comprising i) Ni and Al2O3, ii) NiO and Al2O3, iii) NiAl2O4, or iv) a combination of two or more of i), ii) and iii);
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 1000° C. or more to form a product stream comprising H2, a direction of flow for the reactant stream within the reaction zone being reversed relative to a direction of flow for the mixture.
