摘要
柴油车热效高,功率大,具有良好的经济性和可靠性,所以柴油车的生产现已得到突飞猛进的发展。但柴油车尾气的排放破坏了大气的臭氧层,造成了环境污染,对柴油车尾气的净化处理势在必行。介绍了脱除柴油车尾气NOx催化剂的生产工艺,催化原理及催化剂的组成,并在模拟装置上活性测试。产品满足国Ⅳ排放标准。
Diesel has a good economy and reliability, with a high thermal energy efficiency and a large power, so a large of diesel is produced. However, diesel exhaust destroys O3 atmosphere and causes environmental pollution. It is imperative to purify diesel exhaust. We elaborate catalyst preparation process, principle and composition on NOx removal from diesel exhaust. Moreover, their activities are characterized by a simulated rig. The product reaches National IV emission standards.
