【Abstract】 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.更多还原
