摘要： 采用程序升温还原法(TPR)制备Pt/HZSM-5催化剂，并进行XRD表征。以不同催化裂化汽油馏分和正庚烷为原料，在小型连续固定床反应装置上考察了改性HZSM-5分子筛在一定条件下的芳构化性能。结果表明，当Pt的浸渍质量分数为0.5%，压力为1.5 MPa，温度450 ℃，氢油体积比为800∶1，体积空速为2.0 h-1时，Pt/HZSM-5催化剂对正庚烷的芳构化活性和稳定性最佳；当压力为1.0 MPa，温度为450 ℃，氢油体积比为800∶1，体积空速为2.0 h-1时，Pt/HZSM-5催化剂对催化裂化汽油50～100 ℃馏分和80～120 ℃馏分表现出较好的芳构化性能。

Abstract: HZSM-5 zeolite supported on Pt catalysts were prepared by impregnation and temperature-programme reduction (TPR), and characterized by X-ray diffraction (XRD). By using FCC gasoline fractions [KG*4]of [KG*4]different [KG*4]model [KG*4]compounds and n-heptane on a small-scale fixed bed reactor, modified ZSM-5 investigated reviewed their aromatization performance under definite condition. The experimental results show that, when Pt/HZSM-5 content 0.5% in Pt, reaction under pressure 1.5 MPa, temperature 450 ℃, hydrogen to oil ratio of 800∶1 and volume space velocity of 2.0 h-1, Pt/HZSM-5 catalyst for the n-heptane aromatization activity and stability was the best; when the reaction under pressure 1.0 MPa, temperature 450 ℃, hydrocarbon to oil 800∶1 ratio and volume space velocity of 2.0 h-1, Pt/HZSM-5 catalyst showed better aromatization performance by distillated FCC gasoline between 50~100 ℃ and 80~120 ℃.
