摘要:
氮氧化物(NOx)是大气污染长久治理的重点,工业主流氨气选择性催化还原NOx的技术核心是脱硝催化剂,研发环境友好型高效脱硝催化剂是世界环保的共同需求。简述了脱硝需求背景、脱硝催化剂应用现状及现存问题,概述了贵金属、金属氧化物及离子交换型分子筛3大类脱硝催化剂的研究进展;重点论述了环境友好型稀土基脱硝催化剂的研发历程,以及船用无毒选择性催化还原(SCR)脱硝催化剂的研究进展。我国自主研发的稀土基脱硝催化剂是第二种实现规模化工业应用的烟气脱硝催化剂,被国家三部委指定为钒基催化剂的替代产品,成为未来工业脱硝应用的重点新材料。从行业NOx超低排放驱动及恶劣工况脱硝难度两方面,探讨了脱硝催化剂面临的新挑战,指出抗水硫中毒能力强的超低温催化剂、耐水热稳定性强的高温催化剂及脱硝催化剂多功能化治理其他污染物,是今后脱硝催化剂发展的重点。
Abstract:
Nitrogen oxides (NOx) are the long-term focus of air pollution control, the technological core of industrial mainstream selective catalytic reduction of NOx with ammonia is deNOx catalyst, and the research and development of environmentally friendly and highly efficient deNOx catalysts is a common requirement of the world’s environmental protection. The background of deNOx demand, the application status of deNOx catalysts and existing problems are briefly described, and the research progress of three types of deNOx catalysts, including noble metals, metal oxides and ion-exchanged zeolites are summarized. The development progress of the environmentally friendly rare earth-based deNOx catalysts and the research progress on non-toxic SCR catalysts for marine deNOx are highlighted. The rare earth-based deNOx catalyst independently developed by China is the second flue gas deNOx catalyst for large-scale industrial application, which has been designated as a substitute for the vanadium-based catalyst by the three state ministries and the national development and reform commission, and will become a key material for industrial deNOx applications in the future. From the two aspects of ultra-low NOx emission demand driven by different industries and the difficulty of deNOx in severe working conditions, the new challenges of deNOx catalysts are discussed. The ultra-low temperature deNOx catalysts with strong anti-water and sulfur dioxide poisoning abilities, the high temperature deNOx catalysts with high hydrothermal stability, and the new multifunctionalization of deNOx catalysts for treating other pollutants, are the focuses of future development.
