Experimental and Mechanism Study of Homogeneous N₂O Decomposition with Biomass Gasification Gas and Its Components

Abstract

The influence of biomass gasification gas and its components on homogeneous N 2 O decomposition was investigated in a lab-scale vertical fluidized bed at 900°C in this article. The results indicated that thermal decomposition contributed a large portion of N 2 O reduction. In the absence of oxygen, the N 2 O decomposition was increased with the rising of reburning gas content, with the order of H 2 > CO > CH 4 . While with the increasing of the oxygen content, the N 2 O decomposition was decreased using H 2 and CO as the reburning gases, while it could be increased using CH 4 as the reburning gas.
