What is the main component of the vulcanizing agent used for catalyst pre-vulcanization in hydrogenation units? What else is there besides carbon disulfide? Our company currently produces sulfur; how can we manufacture sulfiding agents?
The main components of the vulcanizing agents used for catalyst pre-vulcanization in hydrogenation units usually include carbon disulfide and sulfur. If your company already produces sulfur, you can consider processing it together with substances with an appropriate carbon content (such as petroleum coke, coal, etc.) through a reaction to produce carbon disulfide, which can then be used to manufacture vulcanizing agents. It is recommended to consult professional chemical engineers or to carry out relevant technology introduction and research and development. .
Vulcanizing agents can include dimethyldisulfide, carbon disulfide; sulfur can also be used directly for vulcanization!
The vulcanizing agent we use is dimethyldisulfide
Wow, our factory happens to produce dimethyldisulfide
Presulfurization is the process of converting an oxidized catalyst into a catalytically active sulfided catalyst with relatively weak stability, using low-cost sulfides. Common vulcanizing agents include organic sulfides such as thioethers or thiols; inorganic carbon disulfide can also be used, as well as oils with a high sulfur content. Sulfur is generally not used for the presulfurization of hydrogenation catalysts.
Using sulfur as a vulcanizing agent – I’ve heard of it for the first time. Has anyone ever used it?
It seems that guy doesn’t understand what catalyst sulfiding entails in the petrochemical hydrogenation process; he probably thinks it’s the same as rubber vulcanization. Don’t argue with laypeople; he says that launching rockets is done by boiling water, so just pretend to believe him
That’s correct; generally, pre-hydrogenation in hydrogen production is carried out using sulfur-containing feed oils for pre-sulfurization
