Abstract

Abstract: C MAS NMR has been performed in situ to investigate the activation of ¹³C labeled propane under a mild condition over Ga-modified H-ZSM-5 catalysts prepared via different methods. The results indicate that the ion-exchanged and/or its related Ga species are the highly active catalytic components, while impregnated Ga species is not the active species for propane activation at 573 K.

Key words: In situ MAS NMR, Propane, Activation, Mild condition, H-ZSM-5
