Patent ID: 11059721

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 CuxFeyMnzOt, where CuxFeyMnzOt is a chemical composition with 0<x≤3 and 0<y≤3 and 0<z≤3 and, 0<t≤5. For example, CuxFeyMnzOt may be one of CuMnFeO4, CuFe0.5Mn1.5O4, CuFeMn2O4, CuFe2MnO4, 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 CuxFeyMnzOt with methane generates a product stream comprising at least 50 vol. % CO and H2.
