Abstract
Description
1. Technical field
[0001] The invention relates to a method for treating presulfided catalyst outside a device, in particular to a method for sulfurizing a hydrogenation catalyst outside a protector. 2. Background technology
[0002] As we all know, hydrogenation catalysts that use Group VIB and Group VIII metals (especially molybdenum, tungsten, cobalt, nickel) as active metals can play their role to the maximum after sulfuration treatment before use. The relationship between sulfuration effect and catalytic performance Therefore, hydrogenation catalyst vulcanization technology has been widely valued by developers and manufacturers.
[0003] After years of development, in-vessel vulcanization has become quite mature and plays a huge role in the hydrogenation process. However, with the further improvement of people's understanding, it is found that this technology has the following insurmountable defects: (1) the starting site needs to be equipped with corresponding vulcani...
