A novel Pt ion-exchanged Zn-silicate catalyst was developed, providing an inexpensive catalyst for the selective aromatization of light paraffins. Similar to the Pt/Ga-si1icate, the Pt/Zn-si1icate was revealed to be a bifunctional catalyst. Pt promotes the dehydrogenation of paraffin to olefins, while Zn ion in the Zn-silicate is effective for the selective conversion of olefin to aromatics. The Pt in the Pt/Zn-silicate significantly reduces the catalyst decay due to the coke deposition and markedly accelerates the regeneration of the decayed catalyst by promoting the combustion of the deposited coke with air. The difference in the catalytic behavior between Gn-silicate and Zn-silicate was also discussed from the results of characterizations of these catalysts.
