| Outline of Final Research Achievements |
NOx is one of the typical pollutants of the global environment, the reduction and removal of NOx is a very important problem. Diesel vehicles is known in the points as the high heat efficiency, the energy-saving and low CO2 emissions. Since diesel vehicle is operating at excess air condition, the exhaust will contain a large amount of NOx and oxygen, it is impossible to purify NOx by using of the three-way catalyst as gasoline vehicles. The urea SCR device has been put into practical use as a post-treatment device for diesel NOx. It does not reach the still consummate technology because it has been left many problems.
In this study, we developed a new selective reduction method using dimethyl ether (DME) as a reducing agent, which is easier to use than the current urea SCR system, and aimed at the establishment of effective NOx post-processing method. The results showed that this method can be a new processing system.
