摘要
The influence of biomass gasification gas reburning on N2O emissions was investigated in this article. Experiments were carried out to reveal several factors on the N2O decomposition and NO formation characteristics, including the temperature, biomass gasification gas content, bed material of SiO2, and initial oxygen content. The results indicated that the decomposition of N2O could be promoted with the increasing of temperature, the biomass gas content, and the presence of SiO2, but be slightly decreased with the increasing of initial oxygen content. The maximum N2O decomposition reached nearly 100% at temperatures higher than 900 degrees C and biomass content over 1.0%. NO was formed as a minor decomposition product of the N2O, and its formation agreed well with the N2O decomposition.
