摘要

采用浸渍法制备了CeO2-Fe2O3/TiO2脱硝催化剂

研究了反应温度对不同铈钛摩尔比催化剂脱硝效率的影响，以及负载10%CeO2和3%Fe2O3的催化剂的抗硫性能和抗钾、钠碱金属盐中毒性能。试验结果表明:CeO2-Fe2O3/TiO2催化剂最佳反应温度为350 ℃；铁铈氧化物催化剂的最佳组分配比为CeO2摩尔分数10%

Fe2O3摩尔分数3%

NO脱除率可达95.65%； 10%-3%CeO2-Fe2O3催化剂具有良好的抗硫性能；钾、钠碱金属盐对催化剂均有一定的毒化作用

但未对催化活性成分的晶相产生影响

只是削弱了活性成分与载体间的相互结合作用

且钾盐对催化剂活性的影响大于钠盐;钾、钠碱金属盐使催化剂中毒失活可能是由于催化剂NH3吸附能力下降

吸附量减少。
