Abstract

Materials, methods of making, and methods of providing a trimetallic oxygen carrier for converting methane containing fuel to synthesis gas. The trimetallic oxygen carrier comprises CuFeMnO, where CuFeMnOis a chemical composition with 0<x≤3 and 0<y≤3 and 0<z≤3 and, 0<t≤5. For example, CuFeMnOmay be one of CuMnFeO, CuFeMnO, CuFeMnO, CuFeMnO, or Cu impregnated on FerMnsOu, Fe impregnated on CurMnsOu, Mn impregnated on CurFesOu where r>0, s>0 and u>0 and combinations thereof. Reaction of trimetallic CuFeMnOwith methane generates a product stream comprising at least 50 vol. % CO and H.
