increased with an increase in the n-hexane conversion, suggesting that BTX are formed mainly from propylene and butenes. The propylene selectivity was decreased from ca. 32 to 17 C-% when the n-hexane conversion was increased from ca. 88% to 100%. On the other hand, the selectivity to ethylene was increased while the selectivities to butanes were decreased with an increase in the n-hexane conversion. These facts suggest that ethylene would be formed not only by n-hexane cracking but also by butane cracking. Meanwhile, the selectivities to methane and ethane were slightly increased with an increase in the n-hexane conversion. Figure 12. Change in products’ selectivities with n-hexane conversion on HB(12) catalysts. Reaction conditions: Pn-hexane = 6 kPa; W/Fn-hexane = 12.8–64 g h/mol; temperature 923 K, TOS = 15 min. Products abbreviations: see Figure 11. 2.2.2. Comparison of HB(77) and Acid-Treated HB Catalysts Figure 13 shows the change in n-hexane conversion with TOS for the HB(77) and acid-treated HB(77) catalysts at 923 K. A slight decrease in the n-hexane conversion from 100% at TOS of 15 min to ca. 95% at TOS of 90 min was observed for the HB(77). Obviously, the catalytic stability of the HB(77) was higher than that of the Al-rich HB(12) (Figure 10). However, the n-hexane conversion was decreased to ca. 73% at TOS of 210 min, and the catalytic stability was still not satisfactory. Thus, the catalytic performances of dealuminated HB zeolites with a much lower amount of acid were considered. All the acid-treated HB(77) catalysts showed high initial n-hexane conversions (>97%). Compared to the HB(77), HB(77)-NT(1 M, 1 h) showed slightly higher catalytic stability. By increasing the HNO3 concentration and treatment time, the catalytic stability was further improved. A slight decrease in n-hexane conversion from ca. 97% at TOS of 15 min to ca. 93% at TOS of 210 min was observed for HB(77)-NT(2 M, 16 h). 89PDF Image | Zeolite Catalysis
