Cu-ZSM-5上NO催化分解的研究

STUDY ON THE NO DIRECT CATALYTIC DECOMPOSITION OVER Cu ZSM 5 CATALYSTS

考察了不同温度及不同空速条件下，Ｃｕ－ＺＳＭ－５、Ｃｕ／Ａｌ２Ｏ３及Ｃｕ／ＳｉＯ２等催化剂上ＮＯ直接分解的性能，并采用ＸＲＤ，ＴＰＲ及ＳＥＭ等手段对催化剂进行表征，将表征结果与催化剂活性相关联。

The reaction performance of the NO direct decomposition over Cu ZSM 5 Cu/Al 2O 3 and Cu/SiO 2 was inverstigated.The catalysts were characterized by XRD TPR and SEM.For Cu ZSM 5 prepared by the disperse method the activity was much higher than the others.The reasons were discussed briefly.
