Hydrogenation catalysts that do not require sulfur injection in production
Thread Content
Who has used hydrogenation catalysts that do not require sulfur injection in production, and which company is that? Is it a precious metal? What device? .
Generally, sulfur injection is not required for the hydrogenation of petroleum products; sulfidation is carried out only at the start of operation. Once sulfidation is complete, the presence of sulfur in the feed oil ensures that the sulfur content in the catalyst does not get lost. Hydrogenation of coal tar generally requires the addition of a small amount of sulfur, as the raw material contains little sulfur and plenty of nitrogen.
Hydrogenation catalysts do not require sulfur injection during normal operation; the catalyst exists in a sulfided state, while precious metal catalysts exist in a reduced state – the two are different
When producing hydrogen and replacing catalysts, we have used a hydrogenation catalyst that does not require sulfiding.
Is it a catalyst for carbon monoxide conversion?
“Xunkai Catalysts boasts a comprehensive range of hydrogenation catalyst products, including nickel-based Reney catalysts, nickel-supported catalysts, copper-zinc catalysts, copper-silicon catalysts, and precious metal-supported catalysts – both in powder form and for fixed-bed use. These catalysts have been successfully applied in processes such as hydrogenation, dehydrogenation, reductive amination, and desulfurization across industries including those involved in 1,4-butanediol, caprolactam, fatty alcohols, organic amines, butyl octanol, HPPO, petroleum resins, dye intermediates, as well as pharmaceutical and pesticide intermediates.

It’s probably a problem with the raw materials here; anyway, we don’t need to add sulfur during normal production
Whether sulfur is added or not depends mainly on the catalyst’s requirements regarding sulfur content, as well as the level of sulfur content in the raw materials; a comprehensive consideration is needed to make a decision
