CATALYTIC DECOMPOSITION OF N2O OVER STEAM-ACTIVATED FeZSM-5 WITH DIFFERENT CRYSTAL SIZES

摘要

Introduction Catalytic decomposition of nitrous oxide (N2O) has received much attention, because N2O has a significant impact on the destruction of the ozone layer besides its greenhouse effect. FeZSM-5, especially after steam activation at high temperature, is reported to be an effective catalyst for catalytic decomposition of N2O. However, little work has been done on investigating the effects of an internal effectiveness on the catalytic activity.
