摘要
综述了目前国际上由低碳烃催化还原NO_x催化剂的研究现状,分析了金属氧化物催化剂、贵金属催化剂、分子筛催化剂以及双功能催化剂各自的优势和存在的问题。对失活原因以及反应机理作了简单概述,最后提出展望。
The advantages and disadvantages of oxides, precious metals, molecular sieves and bifunctional catalysts for reduction of NOx by lower hydrocarbons under lean-burn conditions have been analyzed and interpreted. The reasons of deactivation of these catalysts and the reaction mechanisms under such conditions were also discussed preliminarily and the prospects for the future works were proposed.
