CATALYTIC DEGRADATION PERFORMANCE OF TOLUENE OVER CuxMn1-xCe0.75Zr0.25Oy

  • 摘要: 采用溶胶凝胶法制备了双主金属、双助剂的CuxMn1-xCe0.75Zr0.25Oy催化剂,在固定床反应器中评价了催化剂降解甲苯的性能,并采用XRD、H2-TPR、O2-TPD和Raman对催化剂进行表征。试验结果表明:催化剂中Cu含量的增加有助于增强Cu-Ce金属之间的相互作用,增加催化剂中的氧空位浓度和晶格氧含量,提高催化剂低温还原性,从而促进催化活性的提高。Cu1CeZr催化剂降解甲苯活性最好,其完全降解甲苯的温度(T100)为220℃,比Mn1CeZr催化剂低60℃。
