摘要
综述了催化还原法消除氮氧化物研究现状、发展趋势及反应机理,特别是对烃类选择性催化还原氮氧化物过程进行了说明。分析了分子筛型、金属氧化物型、贵金属型和吸附-还原型催化剂等不同类型催化剂的特点及存在的问题,并指出了研究工作今后可能的发展方向。
The catalytic reduction of NO_x was reviewed with the emphasis on the progress of studies, developing trend and the reaction mechanisms of the selective reduction of NO_x with hydrocarbons. Four kinds of catalysts, molecular sieve, metal oxide, noble-metal and adsorption-reduction catalysts, were discussed, including their characters and existing problems. The works required in the future are also pointed out.
