摘要
催化重整预加氢催化剂主要是由载体和金属活性组分组成,最常用的预加氢催化剂的金属组分是Co-Mo、Ni-Mo、Ni-W体系。主要论述了催化重整预加氢催化剂的国内外技术进展,着重论述了国内重整预加氢催化剂的性质、特点及研发单位,提出了重整预加氢催化剂的发展方向,催化重整预加氢催化剂对直馏汽油要有良好的适应性,空速高,反应温度低,活性稳定性好,能够满足工业上长周期运转的需要。
The pre-hydrotreating catalyst for reforming unit are made up of carrier and metal active component,the most commonly used of metal active component for pre-hydrotreating are Co-Mo,Ni-Mo,and Ni-W.The article summarized the technology progress of pre-hydrotreating catalyst for reforming unit at home and abroad,emphatically discussed the activity and scientific research situation,put forward the future developing direction of pre-hydrotreating catalyst for reforming unit.The pre-hydrotreating catalyst should have high space velocity,low reaction temperature,high activity and stability in distilled gasoline pre-hydrogenation and could meet the need of long running production.
