If the catalyst in the reactor is not dried, what effects will this have during startup?
An aqueous catalyst can cause damage to the catalyst when in contact with high-temperature sulfurized oil, and it affects the sulfidation efficiency of the catalyst.
The significance of dehydration can be understood as increasing the strength of the catalyst after drying; otherwise, when the feed oil is heated, water will boil and cause the catalyst’s structure to break down.
The reactor pressure drop becomes quite noticeable during use, right?
It can cause the catalyst to break apart, increase the pressure difference in the reactor, reduce its catalytic efficiency, shorten its lifespan, and increase the likelihood of carbon deposition, among other issues.
Steam causes the catalyst to break apart after it is heated
Those involved in production should avoid taking risky actions; failure to dry the materials may cause damage to some of the catalysts, resulting in significant losses
