摘　　要：氮氧化物(NOx)是大气的主要污染物之一,选择性催化还原技术是降低车用柴油机排放NOx的有效措施。概述了尿素选择性催化还原(Urea-SCR)技术的机理,介绍了国内外Urea-SCR技术的发展及应用以及数值模拟技术在SCR中的应用及发展,提出了目前尚待研究的几个问题,展望了SCR研究领域的未来发展方向。NOx is one of the main pollutants in the atmosphere, and selective catalytic reduction technology is an effective measure to reduce NOx emissions from diesel engines. The reaction mechanism of Urea-SCR is provided in the article. The technology development and application of Urea-SCR at home and abroad are introduced, and the simulation techniques and development of SCR are also overviewed. Several problems to be studied are proposed in this paper. At last, the future development direction in the field of SCR is presented.
