摘要
H2O和S02是烟气中的固有成分,而低温选择性催化还原法(LT-SCR)催化剂易受烟气中H2O和S02中毒.元素掺杂改性是最有效的提高SCR催化剂抗水、抗硫性的方法之一.本文介绍了元素掺杂改性提高Mn基、V基、Ce基、Fe基等低温SCR催化剂抗水、抗硫性的方法以及理论计算在抗水、抗硫低温脱硝催化剂设计中的应用,以期为提高低温SCR催化剂抗水、抗硫性优化设计及构建提供理论基础.
Abstract
H2O and SO2 are intrinsic components in flue gases.Low-temperature selective catalytic reduction(LT-SCR)catalysts are susceptible to H2O and SO2 poisoning.Elemental doping is one of the most effective methods to improve the water-and sulfur-resistance of SCR catalysts.The method of improving the water-and sulfur-resistance ofMn-,V-,Ce-and Fe-based low-temperature SCR catalysts by element doping was introduced,and the application of theoretical computation in the design of water-and sulfur-resistance of low-temperature DeNOx catalysts was presented.The aim is to provide a theoretical basis for the optimal design and construction of improved water-and sulfur-resistance of LT-SCR catalysts.
