研究了再燃-NO反应∑ijCiHj + NO → HCN + . . .,其是通过与气态烃反应的一氧化氮（NO）的还原途径。从元素反应的组合推导出了全局再燃NO速率表达式。然后，通过关联预测的简单烃类火焰的物种配置文件的全球速率表达式和速率常数。这个总的再燃-NO速率常数可以表示为2.7 × 106 exp（−18 800/RT）（gmol/cm 3 s）。该表达式和常数适用于大气压，当量比范围为1.0 - 2.08的轻烃再燃气体（CH 4和C2 H4）。
An investigation of a global reburning-NO reaction, ∑ijCiHj + NO → HCN + . . ., which is a reduction pathway of nitric oxide (NO) by reaction with gaseous hydrocarbons, was conducted. The global reburning-NO rate expression was deduced from a combination of elemental reactions. The global rate expression and its rate constants were then determined by correlating predicted species profiles from simple hydrocarbon flames. This global reburning-NO rate constant can be expressed as 2.7 × 106 exp(−18 800/RT) (gmol/cm3 s). This expression and constants are applicable to atmospheric pressure with an equivalence ratio range of 1.0−2.08 for light hydrocarbon reburning gases (CH4 and C2H4).
