Abstract
The thermo-chemical performance of fuel reactor (FR) for chemical looping combustion (CLC) changes with operating parameters. It is essential to optimize these operating variables to achieve the best reactor performance. Based on well-verified computational fluid dynamics (CFD) simulation, uniform design method is employed to study the influence of totally n operating variables each with m levels. With respect to the FR experiments by Son and Kim (2006)(in which fuel is pure methane, and oxygen carrier is the mixture of NiO and Fe2O3 supported by bentonite), the uniform design method has been adopted to optimize the yield of CH4 to CO2. Optimum operating condition (NiO percentage in the activated oxygen carrier of 100 %, reaction temperature of 1123 K, particle diameter of 100 μm, inlet gas velocity of 0.0125 m/s, and solid inventory in FR of 0.51 kg) is obtained, and the dependence of CO2 yield on five operating variables is approximated by the second-order polynomial model based on the uniform design method. The most critical parameter is identified as reaction temperature.
