HYDROCARBON CONVERSION APPARATUS INCLUDING FLUID BED REACTION VESSEL AND RELATED PROCESSES

摘要

Embodiments of a hydrocarbon conversion apparatus are provided, as are embodiments of a hydroprocessing conversion process. In one embodiment, the hydrocarbon conversion apparatus includes a reaction vessel having a reaction chamber and a feed distribution chamber. A riser fluidly couples the feed distribution chamber to the reaction chamber, and a catalyst recirculation standpipe fluidly couples the reaction chamber to the feed distribution chamber. The catalyst recirculation standpipe forms a catalyst recirculation circuit with the reaction chamber, the feed distribution chamber, and the riser. A catalyst is circulated through the catalyst recirculation circuit during operation of the hydrocarbon conversion apparatus.

1. A hydroprocessing conversion process carried-out utilizing a hydrocarbon conversion apparatus including a reaction vessel having a reaction chamber and a feed distribution chamber, a riser fluidly coupling the feed distribution chamber to the reaction chamber, and a catalyst recirculation standpipe fluidly coupling the reaction chamber to the feed distribution chamber, the hydroprocessing conversion process comprising:
injecting a feed stream into the feed distribution chamber; contacting the feed stream with a recirculated catalyst within the feed distribution chamber; conducting the feed stream and the catalyst from the reaction chamber, through the riser, and into the reaction chamber; and returning to the feed distribution chamber through the catalyst recirculation standpipe, the steps of contacting, conducting, and returning performed repeatedly to circulate the catalyst within the reaction vessel.
