| 摘 要： | 制备了加氢改质催化剂Pt/USY、Pt/1.0K-USY和Pt/2.0K-USY,并借助XRD、N2等温吸附-脱附、NH3-TPD和Py-FT-IR表征了这3种催化剂的结构和酸性,同时以预精制FCC柴油为原料,采用固定床反应器研究了上述催化剂的加氢改质反应性能.结果表明,在金属Pt负载量相同和催化剂孔道结构相似的情况下,催化剂的反应活性和选择性主要取决于催化剂的酸量和酸强度以及酸分布,相对而言,具有适宜酸性的Pt/1.0K-USY催化剂更有利于芳烃饱和与选择性开环反应,其加氢改质柴油满足国V标准要求. |

| Abstract: | Pt/USY,Pt/1.0K-USY and Pt/2.0K-USY hydro-upgrading catalysts were prepared. The typical structure and acidity of molecular sieves and catalysts were characterized by XRD,N2 absorption-desorption,NH3-TPD and Py-FT-IR. Then the hydro-upgrading performance of these catalysts was studied in a continuous down-flow fixed bed with stainless steel tubular reactor and refined FCC diesel oil was chosen as feedstock. The reaction results indicated that the activity of the catalysts mainly depended on their acid quantity,acid intensity,and acid distribution with the same Pt content and the similar pore structure. Suitable acidity was more favorable for the aromatic saturation and selective ring opening reaction. The diesel product meets national V Diesel standards. |
| Keywords: | molecular sieves catalyst FCC diesel hydrogenation selective ring opening |
