| 422143000 | Including specific wind box or particulate matter support grid | 7 |
| 20080260596 | Fluidizing Base, Method for the Production Thereof and Associated Fluidizing Device - The invention relates to a fluidizing base comprising a flat sheet ( | 10-23-2008 |
| 20100021354 | FLUIDIZED-BED REACTOR FOR CARRYING OUT A GAS-PHASE REACTION - A fluidized-bed reactor for carrying out a gas-phase reaction, in which a gaseous reaction mixture flows from the bottom upward through a heterogeneous particulate catalyst forming a fluidized bed and internals are arranged in the fluidized bed, wherein the internals divide the fluidized bed into a plurality of cells arranged horizontally in the fluidized-bed reactor and a plurality of cells arranged vertically in the fluidized-bed reactor, with the cells having cell walls which are permeable to gas and have openings which ensure an exchange number of the heterogeneous particulate catalyst in the vertical direction in the range from 1 to 100 liters/hour per liter of reactor volume, is proposed. | 01-28-2010 |
| 20100158765 | SCREENLESS INTERNALS FOR RADIAL FLOW REACTORS - An apparatus 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 apertures disposed within the partitions. The apertures are covered by louvers that extend above the edges of the apertures to prevent solid particles from spilling through inlet apertures. | 06-24-2010 |
| 20140186225 | APPARATUSES FOR DISTRIBUTING FLUIDS IN FLUIDIZED BED REACTORS - A fluid distribution apparatus is disposed in a fluidized bed reactor and includes a distributor pipe configured to carry a fluid and a centerpipe fluidly connected to the distributor pipe and enclosing an annular space for receiving the fluid from the distributor pipe. The annular space is defined by an interior radius including a cylindrical plug disposed concentrically within the centerpipe, an exterior radius including the centerpipe, an upper end including an upper circular plate, and a lower end including a lower circular plate. The fluid distribution apparatus further includes a plurality of inlet nozzles fluidly connected to the annular space and disposed through the centerpipe for distributing the fluid from the annular space to a bed of the fluidized bed reactor. | 07-03-2014 |
| 20140294685 | REACTOR MULTI-PASS GRIDS FOR IMPROVED CATALYST HYDRODYNAMICS - A process and device for the flow of catalyst in a reactor is presented. The device includes a series of grids within a reactor vessel, where each grid includes small openings for the passage of gas and some catalyst particles, and larger openings for the more continuous passage of catalyst. The grids span horizontally across the vessel, and are spaced vertically apart to provide for the flow of catalyst down through the reactor | 10-02-2014 |
| 20150147236 | PROCESS FOR PRODUCING AN ANTI-EROSION COATING ON AN INNER WALL OF A CHAMBER OF A FCC UNIT AND ANCHORING STRUCTURE FOR THE PRODUCTION OF THIS COATING - A process for producing an anti-erosion coating on an inner or outer metal wall of a chamber of a fluid catalytic cracking unit, comprising:
| 05-28-2015 |
| 20160375419 | Fluid Solids Contacting Device - A fluid solids contacting device comprising a vessel; a first grid assembly section which comprises a plurality of horizontal chords spaced horizontally apart from each other and a plurality of grid platforms inserted between the horizontal chords; wherein each horizontal chord comprises a structural member with sufficient mechanical strength to withstand fluidized forces in the vessel; a plurality of chairs attached to an inside surface of the vessel and spaced circumferentially apart to support the structural member; and wherein each structural member is supported on one or more of the plurality of chairs is provided. | 12-29-2016 |
