摘要
预硫化是加氢催化剂必不可缺少的活化步骤，本文概述了加氢催化剂预硫化的方法和原理，重点介绍了目前国内外几种新型预硫化技术及其应用，提出了器外预硫化是预硫化技术发展的方向。
Pre -sulfuration was an indispensable activation step for hydrogenation catalyst. The methods and fundamental of pre - sulfuration for hydrotreatment catalysts were summarized, and several new types of pre - sulfurizing technology and its application at home and abroad were highly introduced. Exsitu pre - sulfuration was the development direction of pre - sulfurizing technique.
