CoY催化N_2O分解及Co^(2+)对(类)分子筛载体热稳定性的影响

N_2O decomposition over CoY and the effect of Co^(2+) on thermal stability of zeolite(-like) supports

用离子交换法制备了CoY系列催化剂 ,考察了它们对N2 O分解的催化活性 .结果表明 :焙烧温度对CoY催化活性的影响与CuY显著不同 ;Co2 + 对Y、ZSM 5分子筛和蒙脱土 (类分子筛 )

CoY catalysts were prepared by ion-exchanged method. Gas chromatography was used for the analysis of N 2O conversion and the evaluation of catalytic activity. The results show that CoY and Co 2+-exchanged zeolite-like catalyst have an unusual hydrothermal stability.
