摘要/Abstract

摘要： 我国的水泥生产以新型干法水泥窑技术为主,使用燃料为高挥发分、低灰分的优质烟煤。水泥生产属于高能耗、高排放行业,控制水泥生产过程能耗、降低碳排放对实现“双碳”目标具有重大意义。燃煤催化剂可以有效地解决水泥生产过程中高能耗、高排放的问题,近年来引起了广泛的关注。本文结合国内外研究现状,系统综述了燃煤催化剂的组成与评价方法、催化剂的催化机理、脱硫脱硝型燃煤催化剂的研究和催化剂在工业生产中的应用。研究改进催化剂添加方式,保证在煤粉中的分散度可以提高催化剂的催化效率,是推进燃煤催化剂工业化使用的关键之处。

Abstract: The cement production in China is mainly based on the new dry cement kiln technology. The fuel used in cement production is bituminous coal with high volatile and low ash. Cement production is a high energy consumption and high emission industry. Controlling energy consumption and reducing carbon emission in cement production process is of great significance to achieve the goal of "double carbon". Coal combustion catalysts can effectively solve the problem of high energy consumption and high emission in cement production process, which has attracted wide attention in recent years. Based on the domestic and foreign research status, the composition and evaluation methods of coal combustion catalysts, the catalytic mechanism of catalysts, the research of desulfurization and denitrification coal combustion catalysts, and the application of catalysts in industrial production were systematically reviewed. Researching and improving the catalyst adding method and ensuring the dispersion in pulverized coal can improve the catalytic efficiency of the catalyst, which is the key to promote the industrial application of coal combustion catalysts.

Key words: cement industry, coal combustion catalyst, ignition temperature, burning intensity, catalytic mechanism, industry application
