Regenerable mixed copper-iron-inert support oxygen carriers for solid fuel chemical looping combustion process

摘要: The disclosure provides an oxygen carrier for a chemical looping cycle, such as the combustion of solid carbonaceous fuels, coal, coke, coal and biomass char, like. is comprised at least 24 weight % (wt %) CuO, 10 wt Fe2O3, inert support, typically calcine. exhibits CuO crystalline structure absence iron oxide structures under XRD crystallography, improved sustained reactivity in temperature range 600° C.-1000° C. particularly fuels carbon coal.
