  • Reducing the nitrogen oxide (NOx) emissions from learn-burn engines:reduction of NOx by catalysis technology
        Nitrogen oxides (NOx) in the atmosphere, as key precursory pollutants, induce the formation of acid rain, photochemical smog, and haze. NOx emissions from vehicles and industrial boilers/furnaces account for over 90% of the total emission. The control of NOx emission is urgently needed, particularly after the successful control of SO2 emission. Catalytic purification of NOx emissions from diesel engines and stationary sources is an essential technology. In these two cases, the common presence of excess oxygen, water vapor and sulfur oxides provide severe conditions for NOx removal. As a result, catalytic purification of NOx emissions from learn-burn engines is a big challenge for the air pollution control. Faced with this challenge, the design principles of NH3-SCR catalysts were investigated and proposed, and thereby developed a series of catalysts with excellent catalytic performance, having been applied widely on diesel vehicle emission control. Also, the structure-activity relationship and reaction mechanism of HC-SCR was intensively investigated, providing a guideline for the design of diesel-SCR process with high efficiency.
