| 摘 要： | 对气体再燃低NOx燃烧过程进行分析,采用量子化学密度泛函理论研究了NH自由基与NO反应的机理,优化了反应过程中反应物、中间体、过渡态和产物的几何构型,并计算了它们的能量,同时进行振动分析,以确定中间体和过渡态的真实性。对NH自由基与NO反应机理与实验结果进行了验证和比较,并通过模拟NH自由基与NO的反应,得出反应通道,对认识再燃脱硝的本质和主要过程具有重要的理论参考价值和实践指导意义。

| Abstract: | The low NOx combustion gas reburning process was analyzed, the mechanism of NH free radical with NO reaction was studied by means of the quantum chemical density functional theory, the geometry of reactants, intermediates, transition states and products in reaction process were optimized, and their energy was calculated, at the same time the vibration analysis was conducted so as to determine reality of intermediates and transition states. The NH free radical and NO reaction mechanism and experimental resul... |
