摘要
介绍石油馏分中主要含氮组分和其结构特性 ,以及典型含氮化合物的加氢脱氮反应网络、反应机理、反应动力学 ,阐述了加氢脱氮催化剂改性的不同途径 :载体的改性、活性组分和助剂的选择。
The hydrodenitrogenation (HDN) reactivities of various nitrogen-containing compounds in petroleum fractions and their structural characteristics are briefly introduced,including their reaction mechanisms,reaction networks and kinetics.Accordingly,new trends in developing high-performance HDN catalysts are also reviewed.The main approaches include the modification replacement of the support,new promoters ,Mo- or W- based nitrides ,carbides and phosphides.
