【摘要】 柴油加氢精制催化剂制备技术的发展大致经历了3个阶段,由此形成了三代柴油加氢催化剂:单层分散的负载型金属硫化物催化剂,多层分散的负载型金属硫化物催化剂和非负载型金属硫化物催化剂。本文对金属硫化钼基柴油加氢精制催化剂的应用背景、制备思想及催化剂研究开发现状进行了系统的总结,对柴油加氢催化剂的发展方向进行了展望。更多还原

【Abstract】 The fabricating technologies of diesel oil hydrotreating catalysts are considered to have developed through three stages in general.Consequently,three generations of hydrotreating catalysts have been formed,which are monolayer-dispersed and supported metallic sulfide catalysts,multilayer-dispersed and supported metallic sulfide catalysts and unsupported metallic sulfide catalysts,respectively.The application background,fabrication thoughts and progress in the researches of the molybdenum sulfide-based hydrotreating catalysts are reviewed systemically,and the opinions with respect to the future development trend of diesel oil hydrotreating catalysts are proposed.更多还原
