Rice husk used as solid fuel for chemical looping combustion (CLC) with Fe2O3/Al2O3 oxygen carriers was investigated in an annular dual-tube moving bed reactor (ADMBR). Nearly 100% of CO2 concentration and 92% fuel conversion were achieved for rice husk combustion conducted with Fe2O3/Al2O3 mass flow rates of 22.7 g/min. The introduction of rice husk/sawdust and rice husk/charcoal and mixtures enhanced the processing capacity because of the higher carbon content. The heat demands for ADMBR were estimated to be roughly 54% of input processing capacity released for both rice husk and rice husk/sawdust gasification, while about 19% of input processing capacity was released for rice husk/charcoal gasification. ADMBR is technically feasible to be served as the fuel reactor for rice husk combustion by CLC to achieve high fuel conversion under appropriate operating conditions without auxiliary fuel.
