Processes and apparatuses for regenerating catalysts used in a hydrocarbon conversion process. The catalyst is separated into a bypass portion and an adsorption portion. The bypass portion is passed to a regeneration zone where coke may be removed. A vent gas from the regeneration zone may include an active additive from the catalyst, like a halogen. The vent gas is sent to an adsorption zone which also receives the adsorption portion. In the adsorption zone, the catalyst will contact and adsorb the active additive and then pass to the regeneration zone. The amount of active additive in the vent gas from the regeneration zone and the adsorption zone is reduced.

Processes and apparatuses for regenerating a catalyst

Processes and apparatus for reforming hydrocarbons to reduce the impact of contaminants created by non-catalyst coking. The reaction zone receives sulfur to inhibit the impact, and a control index is used to control the determine conditions with generally lower pressures. Additionally, a compression zone, pressure control zone and combustion zone operation are provided for the operation of the reaction zone at the generally lower pressures.

Processes and apparatuses for operating a hydrocarbon conversion zone

A system for providing a blended cooling air stream to a cooling zone cooler in a continuous catalyst regeneration system. The continuous catalyst regeneration system includes a first effluent stream in fluid communication with a regeneration cooler, a cooler blower that provides a first air stream that is in fluid communication with the regeneration cooler to form a heated first air stream, a second air stream which is combined with the heated first air stream to form a blended cooling air stream, and a cooling zone cooler in fluid communication with the blended cooling air stream.

Continuous catalyst regeneration system including a blended cooling air stream

A process for providing a blended cooling air stream to a cooling zone cooler in a continuous catalyst regeneration system. The process includes removing a first effluent stream from a regeneration tower, providing the first effluent stream to a regeneration cooler; providing a first air stream to the regeneration cooler to form a heated first air stream, combining at least a portion of the heated first air stream with a second air stream to form a blended cooling air stream, and providing the blended cooling air stream to a cooling zone cooler.
