Hydrogenation catalyst sulfidation problem
Thread Content
In dry-sulfurization using DMDS, if abnormal issues arise during the sulfurization process – such as failures in the sulfurizing agent pump, leaks in the high-pressure air cooling system, or interruptions due to the shutdown of fresh hydrogen supply – what impact will restarting the sulfurization process have on the catalyst? Is it still possible to use the amount of sulfurizing agent injected as a reference for determining the end point of sulfurization after such an interruption? How will the effectiveness of sulfurization be affected? I would appreciate guidance from those with expertise in this area
It should be no big problem; just fix it and then continue as usual
Dry vulcanization of DMDS. If abnormal issues occur during the sulfiding process, such as failures in the sulfurizing agent pump, leaks in the high-pressure air cooling system, or interruptions due to the shutdown of fresh hydrogen supply, what impact will restarting the sulfiding process have on the catalyst? Can the amount of sulfurizing agent used as a reference for determining the end point of sulfiding still be utilized after such interruptions? The sulfiding effect is not affected in any way.
