【 摘 要 】

In this paper, the promoting effects of ash and biomass gas reburning on N₂O decomposition were investigated based on a fluidized bed reactor, with the assessment of the influence of O₂ on N₂O decomposition with circulating ashes. Experimental results show that different metal oxides contained in ash play distinct roles in the process of N₂O 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 N₂O decomposition. It is also found that O₂, even in small amounts, can weaken the promoting effect of ash on N₂O decomposition by using biomass gas reburning.
