摘要： The present invention comprises a process and apparatus for producing olefins from oxygenates in a reactor. This process comprises these oxygenates with a catalyst to produce a gaseous mixture comprising light olefins and by-products, sending the mixture to a single stage cyclone within said reactor to separate said catalyst from said gaseous mixture and then sending said the to a second stage cyclone. The second stage cyclone is located outside of said reactor and it functions to remove the catalyst from the mixture. Then the catalyst can be returned to the reactor after having been treated in a regeneration zone to remove carbonaceous deposits from the catalyst.

摘要： A regeneration process for olefin cracking reactor is presented. The process utilizes the nitrogen waste stream from an air separation plant and the partially combusted effluent stream from the olefin cracking reactor is used to heat the nitrogen waste stream. The control of the heating of the nitrogen waste stream can be achieved through redirection of a portion of the heat from combustion to generate steam.

摘要： Char-handling processes for controlling overall heat balance, ash accumulation, and afterburn in a reheater are provided. Carbonaceous biomass feedstock is pyrolyzed using a heat transfer medium forming pyrolysis products and a spent heat transfer medium. The spent heat transfer medium is separated into segregated char and char-depleted spent heat transfer medium. The char-depleted spent heat transfer medium is introduced into a dense bed of heat transfer medium fluidized by a stream of oxygen-containing regeneration gas. All or a portion of the segregated char is combusted in the dense bed using the stream of oxygen-containing regeneration gas. A portion of the segregated char may be exported out of the pyrolysis system to control the overall heat balance and ash accumulation.

摘要： An apparatus and process are presented for drying a catalyst in a reactor-regenerator system. The process includes a continuous operating system with catalyst circulating between a reactor and regenerator, and the catalyst is dried before returning the catalyst to the reactor. The process uses air that is split between the drying stage and the combustion stage without adding equipment outside of the regenerator, minimizing energy, capital cost, and space requirements.

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.
