Pre-sulfurization of catalysts in natural gas-based hydrogen production hydrogenation reactors
Thread Content
I would like to ask everyone: when performing catalyst presulfurization in the hydrogenation reactor of this device using DMDS, is it also necessary to use oil? Have you been to diesel hydrogenation plants? We use straight-run diesel; so what about the hydrogen production equipment? Is oil needed, or is DMDS simply heated and decomposed to produce hydrogen sulfide? I have no experience at all; I hope for your guidance
Generally, nitrogen and hydrogen are circulated, with DMDS added
We use natural gas as the feed, and the catalysts in the hydrogenation reactors have never been pre-sulfided; there have been no problems for 15 years.
