摘要：
Hexane and propene fully penetrate within the micropores of the Fe-MFI zeolite and strongly adsorb. Decane, tetradecane, isooctane and toluene have a very limited access to the micropores and probably adsorb at the micropore mouths where then can act as reducing agents for NO. Linear alkanes (C-6-C-8), isoheptane and toluene have an easy access to the micropores of the mordenite MSM-20. Henry constants, adsorption enthalpies and entropies have been estimated. Pre-adsorbed carbon dioxide inhibits adsorption of propene and hexane on the Fe-MFI.
