通过计算甲烷、乙烷、乙烯、乙炔、丙烷和丙烯等低碳烃与NO反应的热力学函数和低碳烃在电场作用下产生活性粒子的反应焓变，找出合适的低碳烃作为脱除NO的添加剂。根据计算结果，以丙烷和丙烯为例，利用脉冲电晕加氨分别与丙烷和丙烯协同进行了脱除NO的实验研究，得出了最佳工艺参数。在进口风速为1.2 m/s、出口风速为1.0 m/s、进口温度为80 ℃、出口温度为40 ℃、脉冲电压为50 kV时，加入丙烯的脱氮率可以达到60%，加入丙烷的脱氮率可接近30%。
The thermodynamic functions of NO removal by low carbon hydrocarbons such as methane, ethane, ethene, ethine, propane and propene are calculated，and enthalpy changes of reaction producing activated particles from low carbon hydrocarbons in electric field are calculated to find out the appropriate low carbon hydrocarbons for removing NO. On the basis of calculated results, the experiment was carried out to remove NO by propane and propene with pulse corona discharge and amonia.The optimal process parameters are，inlet wind velocity is 1.2 m/s, outlet wind velocity is 1.0 m/s; inlet temperature is 80 ℃，outlet temperature is 40 ℃,pulse voltage is 50 kV, removal efficiency of NO is 60% with propene, and approach 30% with propane, respectively.
