摘要
综述了国内外在选择合适的载体和制备方法、元素掺杂改性以及调节催化剂结构和形貌等改善低温脱硝催化剂抗水、抗硫性方面的研究成果,探讨了几种典型低温SCR催化剂提高耐水、耐硫性的方法,为今后优化和开发具有耐水和耐硫性能的低温NH3-SCR催化剂提供参考。
Abstract
Global research achievements in improving the H2O and SO2 resistances of low temperature selective catalytic reduction (SCR) catalysts through selecting suitable supports and preparation methods,doping elements and adjusting the structure as well as morphology of catalysts are reviewed.The methods to improve the H2O and SO2 resistance of several typical low temperature SCR catalysts are discussed,which provides reference for optimizing and developing low temperature NH3-SCR catalysts with H2O and SO2 resistance in the future.
