- W974281504 abstract "将预先经酸处理的铝钛硅（ATS）多相陶瓷片先后负载Al0.2Ti0.6Zr0.2O1.9复合氧化物与CeO2活性组分，制得新型CeO2/Al0.2Ti0.6Zr0.2O1.9/ATS复合脱硝催化剂。运用X射线衍射（XRD）、扫描电镜（SEM）手段对该催化剂进行表征，研究催化剂的晶相、微观形貌。评价了催化剂的脱硝活性，研究了H2O和SO2对其脱硝活性的影响。实验结果表明，CeO2/Al0.2Ti0.6Zr0.2O1.9/ATS具有良好的脱硝活性，高活性温度窗口在100-350 ℃，当反应温度为250 ℃时，NO的转化率达98.49%。SO2和H2O在一定程度抑制该催化剂的低温脱硝活性，但随着温度的升高，其脱硝活性逐渐恢复。催化剂中活性组分CeO2具有储硫作用，当有SO2存在时，活性温度窗口向高温区偏移了100 ℃，在250-400 ℃时，H2O的存在反而提高了催化剂的脱硝活性。" @default.
