| 摘 要： | 在一固定床反应器上研究了3种煤焦在不同氧浓度、不同温度下燃烧时NO及N_2O生成特性,还研究了燃烧后气体停留时间对NO和N_2O生成的影响,以及NO的加入对N_2O对生成的影响.研究表明,煤焦燃烧中NO主要由氧气吸附于(-CN)基上形成(-CNO)基后而生成,而N_2O的生成机理则有3个,本文比较了这3个反应机理的相对重要性.

| Abstract: | The formation characteristics of NO and N2O are studied during combustion of three kinds of coal char in a fixed bed reactor under different oxygen concentration, and temperature conditions. It was found that the main mechanism of NO formation is the decomposition of (- CNO) sites,which come from oxygen adsorption to the char surfaces. N2O,however , can be produced by three pathways, the relative importance of the mechanisms were discussed in terms of the experimental results. |
