Research Progress on NOx Purification in Diesel Vehicle Exhaust
The pollution of nitrogen oxides in diesel vehicle exhaust has become one of the main factors of air pollution in China,which has attracted widespread attention.In this paper,the existing diesel exhaust NOx purification technology is reviewed,and the current diesel exhaust aftertreatment technologies mainly include selective catalytic reduction technology,NOx storage-catalytic reduction technology,low-temperature plasma technology,NOx direct decomposition technology NOx and PM simultaneous purification technology,etc.,and analyzes and compares the characteristics of different purification technologies.In the future,it is necessary to further develop low-cost catalysts with high activity and selectivity,as well as supporting exhaust gas purification equipment.
