摘要： This invention relates to regeneration of coked catalyst by combustion so that the catalyst can be reused in a hydrocarbon conversion reaction. The completion of coke burn is generally measured with a combination of temperature or change in oxygen concentration. Dropping outlet temperatures require time to wait for increases in inlet temperature to correspondingly move down the regenerator. Faster response times might be expected from increasing oxygen concentration, but a small increase in concentration can lead to a significant increase in peak burn temperature which negatively impacts catalyst life. Controlled peak burning is difficult over the entire bed by merely controlling inlet and outlet oxygen concentrations. The invention accordingly combines a measured lag time for temperature travel with an inlet temperature ramping step to ensure complete coke combustion with high oxygen efficiency, thus providing a rapid regeneration that permits more time for operation at desired reaction conditions.

摘要： This specification discloses a radial flow continuous reaction/regeneration apparatus. Through employing a rotary device to individually and annularly distributing process fluid and regeneration fluid into a stationary segmented reaction/regeneration box and receiving effluents individually and annularly from the same stationary reaction/regeneration box, the mentioned radial flow continuous reaction/regeneration apparatus can be operated continuously and efficiently without the need for shutting down for regeneration. This radial flow continuous reaction/regeneration apparatus is not only used to separate components by adsorption, such as dehumidification, but also is used in chemical processes to carry out catalytic reaction, regenerate catalyst and used as filtration device to trap particles by changing the filler in the stationary reaction/regeneration box.
