Use of antifoulants in catalytic reactors

Use of antifoulants in catalytic reactors

Use of antifoulants in catalytic reactors

(OP)
I would like to know if there is any good experience with the use of antifoulants to remove gums from the top bed of a desulfurization reactor. When cracked feedstocks are exposed to air (sometimes you have to do it during non routine operations)gums are formed in the top section of the reactor, which increase the pressure drop across the bed.

If there any other procedure that can be applied in these situations?

Thanks

Oilman

Foster Wheeler Q&A site too..
