| Abstract: | Aromatization and isomerization of n- hexane catalyzed by Pt/zeolite were investigated. For Pt/K- β and Pt/K-mordenite as well as for Pt/K-L, the addition of KCl resulted in an increase in selectivity for benzene formation accompanied with a decrease in selectivity for hydroisomerization. A parallelism was found between changes in the benzene selectivity with the KCl addition and in the terminal cracking index. The treatment of Pt/K-FSM-16 with K2CO3 resulted in a decrease in cracking products and an increase in benzene selectivity. At 523 K, Pt/H- FSM-16 catalyst showed high selectivity for methylcyclopentane and cyclohexane. At 623 K, it showed high and durable isomerization activity. This revised version was published online in July 2006 with corrections to the Cover Date. |
