Thermodynamic study on Chemical Looping Gasification of Biomass with the CuMn₂O₄ and CaO dual-effect oxygen carrier

CuMn 2 O 4 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, the active ingredient carriers was performed, thermodynamic analysis reaction performed. The appropriate conditions reactants obtained by taking yield syngas component, carbon conversion rate removal capacity CO main evaluation indicators. optimal value n(CuMn )/n(B) is 0.09, temperature 800°C, pressure standard atmospheric pressure, n(CaO)/n(B) 1.5, n(H O)/n(B) 1. In this system, H can reach 1.1857 mol/mol, 0.33224 50.70%, adsorption 58.08%.
