| Abstract: | By means of passivation process, the self-heating characteristic and stripping of sulfur of presulfided hydrogenation catalysts can be suppressed effectively, the storage and transportation become more convenient and can keep the activity of catalysts. In this paper,the passivation types and mechanism, such as the effect of active site, interaction between carriers and Mo, assistants, etc, on the activity of the passivated catalysts during the process of gas passivation were introduced, and the mechanism of liquid passivation process were discussed simply. |
