Progress in Catalytic Decomposition and Removal of N2O in Fluidized Bed

As a clean fuel combustion technology, the circulating fluidized bed (CFB) has been developed rapidly in recent years, but one of its disadvantages is high N2O emissions. With implementation increasingly strict pollution control standards, decomposition and removal technologies have become main focus current research. This paper reviews latest research on noble metals, metal oxides, molecular sieve other new catalysts methods for removal. The functions are compared existing problems summarized. future directions development considered. Noble metals show satisfactory activity at relatively low temperatures, their catalytic efficiency obviously hindered by O2, NO H2O. In addition, costs insufficient thermal stability limit widespread industrial application. oxide especially oxygen carrier-aided (OCAC), expected to be ideal method CFB boilers due economical feasibility.
