现代柴油机油耗低、动力强,但是排放的尾气中黑烟颗粒物PM(particulate matter)会对环境和人类健康造成危害。随着排放法规的日益严格,净化处理刻不容缓。当前对其排放控制的主要手段是使用颗粒物捕集器DPF(diesel particulate filter)捕集PM,并采用催化剂或提高尾气温度促其燃烧以实现DPF再生。燃料添加型催化剂FBC(fuel borne catalyst)能保证催化剂与PM紧密接触,使DPF在尾气温度范围内即可再生。文章对近年来FBC的研究开发进展进行了总结,并指出了该类催化剂的发展方向,即发展纳米级FBC。
Modern diesel engines have low fuel consumption and strong driving force, but particulate matter (PM) in exhaust emissions can cause harm to the environment and human health. With the increasingly stringent emission regulations, purification treatment without delay. At present, the main means to control its emissions is to use PMF (particulate particulate filter) to capture PM and use catalyst or raise tail gas temperature to promote combustion to achieve DPF regeneration. FBC (fuel borne catalyst) fuel catalyst to ensure close contact with the PM, DPF in the tail gas temperature range can be regenerated. The article summarizes the research and development progress of FBC in recent years and points out the development direction of this kind of catalyst, namely, the development of nanoscale FBC.
