What is a heating sulfidation scheme for transformed sulfur-resistant catalysts? What are the differences between the circulating nitrogen with hydrogen and carbon disulfide scheme, and the process gas with sulfide scheme?
The options of circulating nitrogen with hydrogen and carbon disulfide are both available on the forum. I’ve really never heard of a process gas sulfurization using thioethers – is it by decomposing thioethers into hydrogen sulfide?

Sulfides are likely to be a type of organic compound that is difficult to hydrolyze; their hydrolysis temperature is higher than that of carbon disulfide, and a catalyst is generally required for this process. Therefore, using thioethers to replace carbon disulfide for hydrogenolysis is not very ideal. We have been using carbon disulfide, and it works well; it’s easy to handle. It’s not like some people who turn pale at the mention of carbon disulfide. For the sulfidation plan, see http://bbs.hcbbs.com/thread-1281432-50-1.html
During sulfidation, is it done one by one after each converter is completed, or are several converters sulfidated simultaneously?
What kind of method does your organization want to choose? There are those that burn sulfur, as well as those that use CS2 in reaction with hydrogen
