Catalyst - EOR

Catalyst - EOR

Catalyst - EOR

(OP)
Dear Engineers.
I need some suggestions on a Gas Oil Hydrotreater I am currently working at as process engineer. The reactors have a Ni-Mo type catalyst (fixed bed) that have prematurely come to the EOR (end of run). We have a 3-4 months to go before out shutdown and I need to ensure we product within specs, without reducing feed.
We have tried the following steps already:
- Maximised feed temp
- Minimised feed Sulfur levels

Does anyone have any other suggestions?? I also heard of possibility of introducing liquid-moly catalyst in tour feed but not sure if anyone know about this.

Thanks in advance for all the help.

RE: Catalyst - EOR

If your catalyst is in the end or poisoned, minimising sulphur feed levels and temperature temperature are just palliatives, 3 months is much time, I think before serious damages in the reactors, you have to stop soon or later.

Try to avoid questions, that you know the answer.
