| Abstract: | Adsorption of n-propylbenzene on ZSM-5 type zeolites occurs on both Brönsted and Lewis type acid sites. Alkali cations strongly bind hydrocarbons. One particle of hydrocarbon is adsorbed on one Na+ ion. The strength of the bond depends on the cation radius and decreases in the order: Li>Na>K>Rb>Cs. |
