Abstract
In one exemplary embodiment, a process for regenerating a hydrocarbon conversion catalyst for a hydrocarbon conversion zone can generally include passing the hydrocarbon conversion catalyst through, sequentially, a catalyst-disengaging zone having a first atmosphere, an adsorption zone having a second atmosphere, and a regeneration zone including a combustion zone; introducing an inert gas between the first atmosphere and the second atmosphere; and passing a flue gas from the combustion zone to the adsorption zone.

A process for regenerating a hydrocarbon conversion catalyst for a hydrocarbon conversion zone, comprising:
- (a) passing the hydrocarbon conversion catalyst through, sequentially:
- (i) a catalyst-disengaging zone having a first atmosphere;
- (ii) an adsorption zone having a second atmosphere;
- and
- (iii) a regeneration zone comprising a combustion zone;
- and
- (b) introducing an inert gas between the first atmosphere and the second atmosphere;
- and
- (c) passing a flue gas from the combustion zone to the adsorption zone.
A process for regenerating a catalyst for a hydrocarbon conversion zone, comprising:
- (a) passing the catalyst through the hydrocarbon conversion zone;
- and subsequently,
- (b) passing the catalyst through a regeneration unit, comprising:
- (i) a catalyst-disengaging zone containing an introduced buffer comprising an inert gas;
- (ii) an adsorption zone communicating with the catalyst-disengaging zone via a line wherein the line receives spent catalyst from the catalyst-disengaging zone;
- and
- (iii) a regeneration zone.
