在一台小型循环流化床实验台上研究了焦炭的非均相反应对Ｎ２Ｏ生成与分解的影响。实验发现，用同一煤种在不同方式下制取的焦炭燃烧后的Ｎ２Ｏ生成量也有较大的区别；无氧和有氧两种不同的条件下ＮＯ在焦炭表面以两种不同的反应机理转化成Ｎ２Ｏ。氧在焦炭表面的吸附并不是Ｎ２Ｏ生成的必要条件。无氧存在时，ＮＯ也可以在焦炭表面还原生成Ｎ２Ｏ，而有氧条件下ＮＯ在焦炭表面的反应是ＮＯ向Ｎ２Ｏ转化的主要途径，用三种焦炭进行的Ｎ２Ｏ分解试验表明，各种焦炭对Ｎ２Ｏ的催化分解反应都为一级反应，并得出了相应的反应速率常数。焦炭对Ｎ２Ｏ的生成作用大于焦炭对Ｎ２Ｏ的分解作用。
The effect of heterogeneous coke reaction on the formation and decomposition of N2O was investigated on a small-scale CFB bench. It is found that there is a big difference between the two kinds of coke combustion produced by the same coal in different ways after combustion. NO is oxidized by two different reaction mechanisms on the surface of coke under two different oxygen and aerobic conditions Into N2O. Adsorption of oxygen on the coke surface is not a necessary condition for N2O formation. In the absence of oxygen, NO could also be reduced to form N2O on the surface of coke, while the reaction of NO on the surface of coke under aerobic conditions was the main way to convert NO to N2O. N2O decomposition experiments with three coke showed that various coke pairs The catalytic decomposition reactions of N2O are all first-order reactions, and the corresponding reaction rate constants are obtained. The effect of coke on N2O generation is greater than the effect of coke on N2O decomposition.
