Abstract: In this paper, the promoting effects of ash and biomass gas reburning on N 2 O decomposition were investigated based on a fluidized bed reactor, with the assessment of the influence of O 2 on N 2 O decomposition with circulating ashes. Experimental results show that different metal oxides contained in ash play distinct roles in the process of N 2 O decomposition with biomass gas reburning. Compared with other components in ash, CaO is proven to be very active and has the greatest promoting impact on N 2 O decomposition. It is also found that O 2 , even in small amounts, can weaken the promoting effect of ash on N 2 O decomposition by using biomass gas reburning.
