Particle-resolved simulation and modeling of the conversion rate of coal char in chemical looping with oxygen uncoupling

The high concentration of CO2 and low concentration of O2 at relatively low temperatures of 1123-1223 K are typical reactive atmospheres in the fuel reactor of a chemical looping with oxygen uncoupling (CLOU) unit. Char within this environment can be converted via lean-O2 oxidation and/or rich-CO2 gasification. Conventional models, which either considered the oxidation only or considered the oxidation and gasification contributions independently...
