摘要： A process for a continuous regeneration of a catalyst wherein the regeneration section includes at least two separate zones. The regeneration includes a combustion zone, and an oxygen boost zone, where the process utilizes at least two independent regeneration gas loops for control of the amount of oxygen to regenerate the catalyst.

摘要： A method and apparatus for replacing particles in a process that transfers particles is disclosed. This invention employs a seal zone which is in communication with two zones of the process and in which particles that are being added to the process are purged. This invention allows particles to be replaced without reducing the normal rate of particle transfer through the process, which results in a savings in downtime costs. This invention is adaptable to a multitude of processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated.

摘要： A method of converting a hydrocarbon feed with a catalyst and regenerating the catalyst by contact with an oxygen-containing stream is disclosed. The hydrocarbon conversion process employs a purification zone that purifies a net gas stream and that also removes water from a circulating regeneration gas stream. This method is useful for the regeneration of reforming catalysts comprising L-zeolite.
