EFFECT OF SODIUM CONTENT ON THE ACTIVITY OF Ni-CONTAINING ZSM-5 ZEOLITES
Abstract:
A series of NiZSM-5 zeolites with different sodium content have been prepared, and their acidity, adsorbability and catalytic activity for the conversion of toluene have been studied. The results show that the NiZSM-5 zeolite exchanged with Na~+ ions not only modulates the properties of acid-base of zeolite, but also results in the increase of adsorption of toluene molecule. The Na~+ ions as the adsorbed sites of toluene molecule promote both the metallic and acid-base functions for toluene conver-sion. The promoting effect of Na~+ ion was observed.
