Continuous reforming regeneration
Thread Content
What is a coke sliding test? During normal production, less air is used for black burning compared to white burning, while the oxygen content remains unchanged. In this way, the balance between the coke formation rate and the coking rate is not disrupted, so why can’t it switch to white burning? How can black firing be carried out to remove carbon completely?
I haven’t done it, so I can’t give an opinion
There is no difference in oxygen content between white burning and black burning; in both cases, the coke in the catalyst is burned to completion； Switching from black burning to white burning means making the transition when all the catalyst at the bottom of the regenerator is free of coke ； I didn’t understand the question raised by the original poster; it’s a bit confusing. Isn’t the original poster involved in restructuring work?
Yes! Beginner! I just think that once it’s removed, isn’t it produced again in the reactor? So how can the catalyst at the bottom of the regenerator be completely removed?
