| 摘 要： | 制备了可用于氨选择催化还原消除氮氧化物的Ce-P-O催化剂，通过X射线衍射、扫描电镜、N2吸附、H2程序升温还原和氨程序升温脱附等手段对催化剂进行了表征,并考察了催化剂的性能。结果表明，催化剂在空速20 000 h-1表现出较高的氮氧化物消除活性，NO转化率>90%，在水蒸汽和SO2存在条件下，催化剂具有较好的催化活性和稳定性。

| Abstract: | Ce-P-O catalyst for the selective catalytic reduction of NO with NH3 was prepared and charac- terized by XRD, SEM, N2-adsorption, HE-TPR and NH3-TPD. The catalyst properties were investigated. The results showed that Ce-P-O catalyst calcined at 500 ~C exhibited higher activities for the removal of NOx, NO conversion 〉 90% under the reaction condition of space velocity 20 000 h - 1 and NO conversion were not significantly affected in the presence of H20 and SO2. |
