摘要：CuMn2O4 and CaO were mixed in a certain proportion to prepare dual-effect oxygen carriers. A model of biomass chemical looping gasification with corn cob as biomass, CuMn2O4 and CaO as the active ingredient of dual-effect oxygen carriers was performed, and the thermodynamic analysis of the reaction was performed. The appropriate reaction conditions and the appropriate proportion of reactants were obtained by taking the yield of syngas component, the carbon conversion rate and the removal capacity of CO2 as the main evaluation indicators. The optimal value of n(CuMn2O4)/n(B) is 0.09, the optimal reaction temperature is 800°C, the optimal reaction pressure is standard atmospheric pressure, the optimal value of n(CaO)/n(B) is 1.5, the optimal value of n(H2O)/n(B) is 1. In this reaction system, the yield of H2 can reach 1.1857 mol/mol, the yield of CO can reach 0.33224 mol/mol, the carbon conversion rate can reach 50.70%, and the adsorption rate of CO2 by CaO can reach 58.08%.
