1. A method for producing a syngas from a reduced metal aluminate catalyst, a steam, and a solid fuel consisting of:
reducing the metal aluminate catalyst selected from one or more transition metal aluminates using the solid fuel for producing the reduced metal aluminate catalyst, wherein the one or more transition metal aluminates is selected from the group consisting of Cu+1, Cu0, and Fe+2,
continuously delivering the steam and the solid fuel to the reduced metal aluminate catalyst; and
supplying a heat for producing a continuous stream of syngas, wherein the syngas comprises a product stream consisting of at least >than 50 vol % of H2 and CO,
wherein the solid fuel consisting of a solid carbonaceous fuel selected from the group consisting of a coal, coke, char biomass and biofuel, and
wherein a reaction temperature for producing the syngas from the reduced metal aluminate catalyst, the stream and the solid fuel are greater than 500° C.
