Regarding the problem of high carbon fixation of catalytic cracking (wax oil) catalysts
Thread Content
The maximum carbon setting of the regenerant in our device is 0.64%. The dense phase temperature has been unable to burn, basically around 620. When the temperature is high, the dilute phase (flue gas) temperature quickly rises and exceeds the standard. What is going on?
In the situation you mentioned, it is obvious that the regenerator is in a regular regeneration state. Reduce the feed amount (recycled amount or fresh feed), what happens!
For conventional regeneration, when the feed is reduced, the dense phase decreases and the dilute phase rises sharply. How to deal with this?
What you said is not clear yet, please make it clear. From now on, we can see if your main air volume is too large, and the catalyst may have more subdivisions.
study* Okay, great gods, stand up.
1. The main wind may be biased, causing the dense phase to fail to burn completely. 2. It is recommended to add CO combustion accelerant to prevent the dilute phase from overheating.
The regenerator carbon limit is 0.64%, which is too high. Catalyst activity will inevitably decrease, product distribution will be unsatisfactory, and device efficiency will be poor. Please describe it clearly. Is the analysis a process design or an operation optimization problem?
