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

A regenerator vessel for adsorbing halogen-containing material from a regenerator vent gas stream has a plurality of catalyst nozzles disposed at a top portion of the regenerator vessel. A first gas outlet is associated with a chlorination zone, and a second gas outlet associated with a combustion zone. A drying zone is in fluid communication with an air heater and the drying zone located in a bottom portion of the regenerator vessel. The first gas outlet is configured to withdraw a first gas stream from the chlorination zone and the second gas outlet is configured to withdraw a second gas stream from the combustion zone. The top portion of the regenerator vessel has an adsorption zone having a vent gas inlet port, a vent gas outlet port, and a portion of an annular catalyst bed.

Regeneration vessel adsorption zone and process for adsorbing halogen-containing material and sampling catalyst

A process and apparatus is disclosed for distributing a gas stream into a downwardly flowing catalyst stream in a vessel by feeding the gas stream into a center of the vessel or the catalyst stream into a hollow cap. The gas stream enters the cap and exits the cap flowing upwardly to contact the catalyst stream.

Apparatus and process for contacting catalyst with a gas and reduction

A reforming reactor and process of using same in which the process gas is effectively and efficiently distributed through the non-reactive zone. The non-reactive zone has two portions, a first portion receiving a purge gas and having an outlet for an effluent from a reactive zone disposed beneath the non-reactive zone and a second portion receiving the feed and having an inlet. The inlet is located between the reaction zone and the outlet. A flow distributor separates the non-reactive zone into the two portions.

Apparatus for catalytic reforming hydrocarbons having flow distributor and process for reforming hydrocarbons

Apparatuses and methods are provided for regenerating catalyst particles. In one embodiment, a method for regenerating catalyst particles includes passing the catalyst particles through a halogenation zone and a drying zone. The method feeds drying gas to the drying zone and passes a first portion of the drying gas from the drying zone to the halogenation zone. The method includes removing a second portion of the drying gas from the drying zone and injecting a halogen gas into the second portion of the drying gas. Further, the method includes delivering the halogen gas and the second portion of the drying gas to the halogenation zone. In the method, substantially all of the drying gas fed to the drying zone enters the halogenation zone.
