Pt/USY催化剂上FCC柴油加氢改质反应性能
Hydro-upgrading performance of FCC diesel oil on Pt/USY catalysts
摘要
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.关键词
