Automobile exhaust catalysts and its progress
Ratio . Three-way catalyst can effectively control the CO and HC emissions. But on the NOx reduction capacity will be greatly reduced. To solve this problem , people have been exploring the lean-burn conditions in an effective reduction of NOx in automotive exhaust catalysts . (3 ) the use of surface science in the latest technology. Design and preparation of high atomic or molecular level , high- activity catalyst. To improve the catalyst performance. (4 ) on the catalyst performance evaluation and testing should be close to the real conditions for automotive exhaust . For example: To examine the airspeed is high enough ,GHD glätteisen, when asked to run long enough , water vapor, we should focus on consideration of sulfide . |
