Abstract: Zinc and phosphorus incorporated HZSM-5 catalyst was prepared by adopting incipient wet co-impregnation (Zn-P/HZSM-5). Zn-P/HZSM-5 catalyst exhibited the lowest acidity but the highest aromatization activity with stable performance in the studied period of 16 hr. The process conditions on aromatization reaction and the coke deactivation mechanism of Zn-P/HZSM-5 catalyst were studied on a small-scale, fixed bed reactor using FCC naphtha (75-120 • C). The weight contents of ZnO and P 2 O 5 were 2% and 4%, respec… Show more

“…Several groups have reported that adding phosphorus to Zn/HZSM-5 promotes the activity and stability of the catalysts in light alkane aromatization by decreasing the loss of zinc, [29][30][31] as well as in aromatization of uid catalytic cracking (FCC) fractions. [31][32][33][34] There are only a handful of ZnPHZ catalyst types used in MTA reaction, 35,36 and most of such reports have been focused on the reaction studies, not the catalyst structure. In the remainder of the Introduction, we will present our motivation of synthesizing a hybrid ZnPHZ catalyst.…”
