What to do if the pressure difference in the reforming reactor is high? What factors might be causing it?

Issues such as catalyst carbon deposition in the reactor, blockages in the Johnson net, instrument failures, and whether the quality of the refined oil meets standards – all these need to be checked one by one to determine if there are any abnormalities in the boosting system, the thickenning system, or the condition of the regenerator
Catalyst carbon deposition is the primary cause; analyze the carbon content of the raw catalyst to see if it has increased. Then check whether your feed rate is too high; an excessive space velocity can cause the catalyst to stick to the walls and block the sieve. Try reducing the feed rate first to see if that helps. Furthermore, if internal components such as screens and baffles are damaged, the catalyst leaks.
Well, the processing volume was increased once recently; it seems there’s a high possibility of carbon buildup. Thank you
1. Catalyst carbon deposition 2. Catalyst fragmentation 3. Deposition of suspended solids upstream. In the case of a fixed-bed system, these issues can be resolved by performing appropriate treatment on the catalyst. In the case of continuous regeneration, the catalyst is coked, debris is separated, and the raw material purification is enhanced.
It’s continuous regeneration; the raw materials used might be a bit dirty. Right now, we purchase whatever is cheap
When the catalyst is lifted again, a large amount of catalyst dust is generated; if this dust is not removed in time, it can also lead to an increase in the pressure drop across the catalyst bed.
If the gap in the Johnson mesh of the central cylinder is large, catalyst particles entering the oil-gas system and gradually blocking the fan-shaped cylinder will lead to an increase in the reactor pressure drop, and this pressure drop will continue to rise
What do you refine from your raw materials? Direct steam? Catalytic cracking of heavy naphtha? Hydrogenated coker naphtha? Naphtha from coal? Rubber naphtha?
