Abstract
- In this paper, the FCC gasoline (75~120 ? C fraction) is investigated and studied on the HZSM-5 type zerolite catalysts modified with zinc nitrate and ammonium dihydrogen phosphate which are prepared by impregnation method. The results show that Zn x –HZSM-5 type zerolite catalysts have a high initial reactivity of aromatization but a rapid deactivation. Compared to Zn x –HZSM-5 type zerolite catalysts, the Zn x –P y –HZSM-5 type zerolite catalysts not only have more stable reactivity of aromatization but a property of isomerization. The Zn (2%)–P(4%)–HZSM-5 has the best performance among them. Also, the reaction operational conditions are observed and studied on the Zn (2%)–P (4%)–HZSM-5 type zerolite catalyst. The results are that the optimal reaction temperature is 430 ? C, the liquid hours space velocity (LHSV) is 1 hr -1 and the reaction pressure is 0.1Mpa. [ABSTRACT FROM AUTHOR]
