    摘要: FCC catalyst is regenerated in a process providing increased coke-burning capacity without additional heat evolution or air consumption. The process uses a two-stage regeneration arrangement providing initial coke combustion in a low catalyst density-high efficiency contact zone followed by substantial separation of catalyst and regeneration gas and complete regeneration of catalyst particles in a dense bed regeneration zone. Catalyst and gas flow cocurrent prior to this separation but flow countercurrent after the separation. An effective control scheme for regulating oxygen addition to the final zone is also disclosed. This process is applicable to FCC operations for conventional and residual feedstocks.

    摘要: Alkylation systems and processes are provided herein that include a slurry reactor. The slurry reactor receives a reactor feed slurry including catalyst and liquid isobutane, a olefin feed, and a circulating reactor vapor stream, where the slurry reactor produces a reactor liquid effluent stream, the reactor liquid effluent stream including catalyst, isobutane, and a liquid alkylate product. The catalyst in the reactor feed slurry can be regenerated catalyst from a catalyst regenerator. The catalyst can be regenerated after being removed from the liquid alkylate product and isobutane in the reactor liquid effluent stream.

    摘要: An distributor arrangement introduces spent FCC catalyst more uniformly across the dense bed of the regenerator to provide more even contact with regeneration gas in order to avoid hot spots and zones of incomplete combustion. The invention forms a fluidized hopper to collect spent catalyst and a horizontally extended header with multiple horizontally extended outlet arms to place catalyst into the regenerator. The invention may use an aeration means to fluidize the header to further assist catalyst flow. Furthermore, the spent catalyst delivered to the top of the regenerator dense reduces NOx emissions in the flue gas.

    摘要: An arrangement for the controlled production of an essentially linear array of hydrocarbon feed injection jets maintains stable and reliable jets by passing individual piping for each jet through a support shroud that is located in a contacting vessel. Controlled atomization is provided by independently injecting a uniform quantity of gas medium into each of the plurality of uniformly created feed injection streams upstream of a discharge nozzle that separately discharges each mixed stream of hydrocarbons and gas medium into a stream of catalyst particles at or about the inner end of the support shroud. The feed injection jets are suitable for positioning in an inner location of large contacting vessel. Uniformity of distribution is obtained by dividing the hydrocarbons streams from an oil header into an individual oil conduit for each spray injection nozzle. The individual oil conduits each pass the feed perpendicularly into a separate mixing conduit that discharges a mixture of gas medium and oil into each spray nozzle. Another header supplies individual gas conduits that pass the gas medium longitudinally into the mixture conduits at a right angle to the catalyst stream. The ends of the mixture conduits dispose the spray injection nozzles in positions to produce an array of feed injection jets.

    摘要: A process for improving the yield of ethylene and propylene from a light naphtha feedstock includes obtaining light naphtha feedstock from a primary cracking zone having a cracking catalyst. The light naphtha feedstock is contacted with an olefin catalyst in an olefin producing zone to produce an ethylene- and propylene-rich stream. After reacting with the olefin catalyst, the ethylene- and propylene-rich stream is separated from the olefin catalyst from in a separator zone. At least a portion of the olefin catalyst is regenerated by combusting coke deposited on a surface of the olefin catalyst in an oxygen-containing environment, and at least a portion of the olefin catalyst is heated. These portions could be the same one or they could be different. In some embodiments, at least a portion of the olefin catalyst could be neither regenerated nor heated. The olefin catalyst is returned to the olefin producing zone.
