The reactor includes, in an upright tubular reactor vessel: a packing region for housing a continuous packed bed of granular packing; and an outer and an inner passages disposed outside and inside the packing region, respectively, allowing a fluid to flow in the axial direction. The reactor is configured so that the fluid can pass between the packing region and the outer passage and between the packing region and the inner passage. The reactor further includes at least one of an outer partition structure and an inner partition structure.

  • Patent number: 7998429
    Abstract: An apparatus is presented for contacting a bed of particulate material with a cross flowing fluid, which maintains the bed of particulate material within a retention volume. The apparatus includes partitions for retaining particles, with openings disposed within the partitions. The openings are covered by louvers that extend above the edges of the openings to prevent solid particles from spilling through inlet openings, and the design prevents the loss of particles through the openings during cooldown of the apparatus.

  • Patent number: 7951341
    Abstract: A moving bed of catalyst loses activity as it moves through the reactor. Creating multiple passes for the process fluid moving across a catalyst bed, increases the utilization of the catalyst and creates a pseudo-counter current flow of catalyst and process fluid. The flow improves the temperature profile of the bed and allows higher temperature fluid contacting the less active catalyst.

  • Patent number: 7879294
    Abstract: A fine solids recycle apparatus for a fluidized bed reactor comprises an eductor connected to a dipleg extending from a cyclone connected to the reactor, wherein the fine solids particles are removed from the dipleg, mixed with an eductor gas to form an eductor gas-fine solids particles mixture, which allows the return of the fine solids particles to the fluidized bed region, whereby the fine solids is further reacted in the fluidized region to improve reaction efficiency.

  • Publication number: 20100316540
    Abstract: With the help of a fixing device for catalyzer particles, wherein the catalyzer particles are packed in a bed which can be passed through by a gas flow in the direction of gravity, it is intended to achieve a minimum specific pressure loss which will remain low even if dirt should arise from the operating process; a fixing device which has a minimum influence on the period of presence of the gas flowing through; which ensures the reliable hold-down of the catalyzer particles even at high approach velocities; and which is flexible to a certain degree in order to adapt to bed changes. This is achieved by placing at least one layer of a metal braiding (10) on the packed bed (3) of the catalyzer particles, and the metal braiding (10) consisting of individual metal braiding elements (11) which are firmly braided together.

  • Publication number: 20100316541
    Abstract: One exemplary embodiment can include an apparatus for transferring catalyst from a regeneration zone to a reaction zone in a hydrocarbon conversion unit. The hydrocarbon conversion unit can include a transfer vessel, and first, second, and third lines. The transfer vessel can transfer regenerated catalyst from the regeneration zone at a first pressure to the reaction zone at a second pressure where the second pressure is greater than the first pressure. Generally, the first line communicates the catalyst to the transfer vessel and is coupled to a first valve to allow catalyst into the transfer vessel and the second line communicates the catalyst from the transfer vessel and is coupled to a second valve to allow catalyst out of the transfer vessel. The third line for allowing the passage of gas therethrough may be at a pressure higher than the first pressure having a first portion communicating with the transfer vessel and having a second portion coupled to third and fourth valves.

  • Patent number: 7842257
    Abstract: The distribution of fluids within a radial-flow reactor is improved using vertically extended cylinders distributed around the circumference of the vessel. Cylinders with a circular cross-section provide substantial vertical strength, and the configuration minimizes low-flow areas which could cause undesirable reactions. The cylinders are isolated from particles in the reactor by a particle-retaining outer conduit. The cylinders may be fabricated in panels for ease of installation and servicing.
