等离子体与催化剂协同脱除柴油机NO_x的研究

Research on removing NO_x pollutants of diesel with plasma-catalyst technology

在模拟发动机排气条件下对等离子体与催化剂协同脱除柴油机NOx进行了测试。考察了单独等离子体、单独催化、等离子体与催化协同作用下的转化效果,分别测试了NO体积分数、还原HC体积分数、输入能量密度、催化载体类型、温度以及CO,H2,CO2等因素对NOx转化效率的影响。

The test on removing NOx pollutants of diesel with plasma-catalyst technology is taken by a simulating engine exhaust emission. The transformation effects under plasma alone, catalyst alone and plasma-catalyst technology are examined. The influence of concentration of NO and HC, input energy density, CO, H2, CO2, type of carrier, temperature et al on eonversion efficiency is investigated.
