When is the sulfidation process for hydrogenation units usually carried out? How to do it?
First, the vulcanization process relies on a vulcanization catalyst. It is the process of sulfiding the catalyst during its first startup or when the catalyst is regenerated. Second, how to do it. So, the catalyst in its oxidized state is sulfided to become in a sulfided state? Vulcanization is divided into wet vulcanization and dry vulcanization. It’s just that different vulcanization media are used. Wet vulcanization uses a vulcanizing agent abbreviated as DMDS. Dimethyldisulfide. The goal is the same, but the approach differs greatly.
Replace the catalyst with a new one, or convert the catalyst in its oxidized state into a catalyst in its highly active sulfided state!
Then we’ll proceed according to your requirements, right?
I know; I was asking the original poster whether it’s done dry or wet~~~ There is some difference after all~~~
