摘要:
随着世界工业规模的不断扩大以及社会不断发展,越来越多的发动机应用于工业生产中,但发动机排放的尾气造成环境污染问题也越来越严峻。如何将发动机尾气污染物消除或净化逐渐成为研究的热点。 目前,催化净化技术是处理大气污染物最有效、应用最广泛的技术之一。如何将开发的粉体催化剂有效的应用到汽车尾气催化净化器并实现工业化应用,其中最关键的因素整体式催化剂的研发。本文介绍了整体式催化剂常用的制备工艺,如溶胶凝胶法、水热法,浸渍法等并对相关的制备原理进行了描述;同时,对整体式催化剂催化净化发动机尾气如一氧化碳(CO),氮氧化物(NOx),碳氢化合物(HC),及炭烟颗粒
Abstract:
With the continuous expansion of the world’s industrial scale and the continuous development of society, more and more engines have been applied in industrial production. However, the environmental pollutions caused by engine exhaust emissions are also more and more serious. How to eliminate or purify engine exhaust pollutants has become a research hotspot. At present, catalytic purification technology is one of the most effective and widely used technologies for the treatment of air pollutants. How to effectively apply the developed powder catalysts to the automobile exhaust catalytic purifier and achieve industrial application, the most key factor is the development of monolithic catalysts. In this paper, the common preparation processes of monolithic catalysts, such as sol-gel method, hydrothermal method, impregnation method, etc. were introduced, and the related preparation principles were also described. Meanwhile, the research progress on monolith catalysts for catalytic purification of main pollutants in engine exhausts, such as carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC), and soot particles, were described in detail. Finally, the problems and development trends of the monolithic catalyst in the catalytic purification of engine exhaust pollutants were summarized and prospected
