摘　　要：以75～120℃的FCC汽油馏分为原料,在连续固定床反应器上考察了Zn P/HZSM 5催化剂的芳构化反应性能,探讨了工艺条件对芳构化反应的影响以及工业化的可行性。结果表明,Zn P/HZSM 5催化剂具有很高的活性、稳定性和芳烃选择性。在温度430℃、压力0 1MPa、空速1h-1的反应条件下,得到了烯烃含量低、芳烃和异构烷烃较协调的汽油调合产品。The catalytic properties of Zn-P/HZSM-5 for aromatization of FCC gasoline were investigated on a small fixed bed reactor using 75-120 ℃ FCC gasoline as the feedstock. The influence of process condition and the feasibility for commercialization were discussed. The experimental results showed that Zn-P/HZSM-5 catalysts had high activity, stability and selectivity to aromatics. Reformulated gasoline with low olefins content and reasonable aromatics /iso-paraffins proportion was obtained at 430 ℃, 0.1 MPa and LHSV 1.0 h^(-1).
