Carbon deposition on continuous reforming catalysts
Thread Content
Is carbon deposition severe in continuous reforming? Isn’t it always carried out under hydrogen-rich conditions? Why does the reforming catalyst need to be regenerated just like the catalysts used in catalytic cracking?
Hydrocracking takes place in a hydrogen-rich environment and also requires regular regeneration. Although reforming also occurs in a hydrogen-rich environment, the hydrogen partial pressure is much lower, resulting in faster carbon deposition； Graphite carbon and soft coke will both be formed.
I don’t know what you’re talking about; it’s best to read the question carefully.
