Abstract:
The study of C-6 hydrocarbon aromatization over Pt/Al2O3, Zn/ZSM-5 and Pd/ZSM-5 showed that the Pd/ZSM-5 has much higher activity than Pt/Al2O3 and Zn/ZSM-5 catalysts due to their characteristic difference in acidity and sensitivity of metal, respectively. The optimum condition for the continuous reactor was obtained when 2% Pd/ZSM-5 catalyst was used at 400℃ with the feed rate of 0.4 ml/min. In addition, conversion of n-hexane using the ZSM-5 supporting catalyst was found to be more selective on the production of p-xylene than o-xylene and m-xylene.
