    Abstract: Processes and systems for cracking feeds to produce olefins are provided. The process for cracking feeds can include converting a first feed containing at least about 50 wt % methanol in a first riser under a first set of process conditions to produce a first effluent enriched in ethylene, propylene, or a mixture thereof, wherein the first effluent contains at least about 25 wt % dry basis propylene and converting a second feed containing C4-C10 light hydrocarbons in a second riser under a second set of process conditions to produce a second effluent enriched in ethylene, propylene, or a mixture thereof. The process can also include combining the first effluent with the second effluent to produce a mixed effluent, separating the mixed effluent to produce a coked-catalyst and a gaseous product, regenerating the coked-catalyst, and recycling the regenerated catalyst to the first and second risers.

    Abstract: 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.
