摘要： This invention relates to efficiently regenerating catalyst particles by minimizing the formation of localized “hot spots” and “cold spots” in a regeneration zone. In one embodiment, the invention includes mixing spent catalyst from a reactor and cold catalyst from a catalyst cooler in a mixing zone and directing the mixed catalyst to the regeneration zone in a fluidized manner with a fluidizing medium. In the regeneration zone, the mixed catalyst contacts an oxygen-containing regeneration medium under conditions effective to regenerate the spent catalyst contained therein.

摘要： The present invention is directed to a swaged catalyst regenerator and processes for using the catalyst regenerator. In one embodiment, the swaged catalyst regenerator includes a regeneration zone having a first major diameter and into which a regeneration medium and an at least partially coked catalyst from a reactor can be fed. The catalyst regenerator also includes a separation zone having a second major diameter. The separation zone is provided to separate entrained catalyst from gaseous components, e.g., combustion products of a regeneration process, and return the entrained catalyst to the regeneration zone. The ratio of the second major diameter to the first major diameter is at least 1.1, 1.4, 1.7, 2.0, 2.3, 2.6 or 2.9. By providing a catalyst regenerator having these characteristics, desirable regeneration characteristics that minimize entrained catalyst loss can be achieved.

The reaction systems are those that use catalysts that comprise molecular sieves, particularly metalloaluminophosphate molecular sieves, especially metalloaluminophosphate molecular sieves which are susceptible to loss of catalytic activity due to contact with water molecules. The methods provide appropriate mechanisms of stopping feed to the reactor and unloading catalyst to protect against loss of catalytic activity that can occur due to contact with water molecules.
