Sulfurization temperature of the hydrodesulfurization unit
Thread Content
I need help: what is the temperature for the first sulfurization of a hydrodesulfurization unit? Thank you!
This depends on the requirements of the catalyst manufacturer, not on personal experience. Moreover, the sulfurization methods for catalysts in different devices vary as well; for ordinary catalysts, the starting temperature for wet sulfurization is 145 degrees, after which the sulfurizing agent is added followed by operation according to the temperature increase curve.
What does sulfidation mean in a hydrodesulfurization unit? Does it refer to catalyst sulfidation? Are they the performance indicators of the hydrodesulfurization unit during operation?
What the friend on the 2nd floor said makes sense; regarding the specific temperature requirements, the original poster should consult the catalyst manufacturer. And it also depends on what type of vulcanizing agent you use. If it’s DMDS, it should generally be around 260 degrees Celsius. At this temperature, DMDS can decompose to release sulfur for the vulcanization reaction.
