摘要
汽车尾气对大气的污染已成为城市大气污染的主要污染源。根据尾气污染物的形成机理,提出研究净化废气中的主要有害成分CO、CH、NOx和炭烟颗粒的方法。氧化还原催化剂是核心技术;以增氧,增加催化反应速度,增长催化反应时间,保证合适催化温度,采用合理结构等净化技术系统研究是技术研究的方向。
The automobile exhaust becomes the main source of atmosphere pollution in city. According to the exhaust pollutant formation mechanism, proposes the method of purifying the main harmful ingredients of CO, CH, NOx and the coal smoke pellet in waste gas. The oxidation reduction catalyst is the core technology. The direction of technical study is to increase catalytic reaction speed and growth catalytic reaction time, guarantee the appropriate catalyzed temperature and adopt the reasonable structure and so on.
