Chemical looping air separation (CLAS), a simple and efficient oxygen production technology, can be efficiently integrated with the moderate or intense low-oxygen dilution (MILD) combustion and oxy-fuel combustion technologies. Mn-based oxygen carrier is considered to be a hopeful candidate for the CLAS, but its redox kinetics has rarely been reported. In this work, the most suitable kinetic mechanisms for reduction and oxidation reactions are determined by thermogravimetric analyses. By coupling the obtained redox reaction kinetics and gas-solid flow hydrodynamics, a one-dimensional model of the interconnected fast fluidized bed and bubbling fluidized bed is built using sequential modular approach for simulating the chemical and physical phenomena in the CLAS process. The effects of main operation parameters on the CLAS performance are investigated by sensitivity analyses. The mole fraction of generated oxygen is found increasing with the increments of reduction temperature and air flow rate. Moreover, the system specific power consumption (SPC) is decreased when the temperatures of the two fluidized beds are similar. SPC can be as low as 0.076 kWh/m(3) at the oxidation and reduction temperatures of 770 degrees C, the air flow rate of 50 Nm(3)/h, and the CO2 flow rate of 23 Nm(3)/h, which is 18% of the energy requirement of conventional cryogenic air separation system.
