(Catalytic cracking term explanation) Regenerated catalyst: A regenerated catalyst refers to a catalyst that has been processed in a regenerator and from which most of the carbon deposits have been removed. =============================
The process of restoring the efficiency of a catalyst whose catalytic efficiency has declined. The regeneration process does not involve the disassembly of the catalyst’s overall structure; it merely uses appropriate methods to eliminate those factors that cause a decline in catalytic efficiency
It mainly works by burning off the coke attached to the catalyst, thereby restoring its activity and enabling the catalyst to be reused.
The catalyst that has had most of its carbon deposits burned off, coming out of the regenerator after regeneration
The process of restoring the efficiency of a catalyst whose catalytic efficiency has declined.
The process of restoring the efficiency of a catalyst whose catalytic efficiency has declined.
A catalyst whose activity has been restored by burning off the coke attached to it through carbonization is called a regenerated catalyst

Catalyst with the outer carbon coating removed by combustion in a regenerator
When a catalyst is used for an extended period in a reactor, coking formed due to carbonization covers the inner and outer surfaces of the catalyst. As the surface area of the catalyst decreases, its activity also decreases. To restore the catalyst’s activity, catalyst regeneration is carried out. Catalyst regeneration is the process of burning the coking that covers the inner and outer surfaces of the catalyst to remove it in the form of CO2 and H2O, thereby restoring the catalyst’s activity. It includes all steps such as unit shutdown, pressure relief and vacuuming, combustion, and cooling.
