摘要： This invention makes possible substantially continuous flow of uniformly distributed hydrogen and hydrocarbon liquid across a densely packed catalyst bed which substantially fills the entire volume of a reactor vessel. Catalyst are selected to be essentially the same density, shape and size at a design feed rate of liquids and gas to prevent ebullation of the packed catalyst bed at the design feed rates. The liquid and gas components of the hydrocarbon feed stream flow into the bed of catalyst and a quenching medium, which is preferably a liquid, is injected into the bed of catalyst. Injection of a liquid quench reduces the gas component of the hydrocarbon feed stream while simultaneously increasing the residence time and reducing the liquid velocity of the liquid component of the hydrocarbon feed stream within the substantially packed bed of catalyst. Injection of a liquid quench also increases penetration and contact of the liquid component into and on the surface area of the catalyst while simultaneously decreasing the viscosity of the liquid component. An apparatus for quenching in hydroprocessing of a hydrocarbon feed stream.

摘要： On-stream catalyst replacement apparatus for countercurrent upstream flow of a gas and hydrocarbon liquid through a downward moving catalyst bed in a reactor vessel. A mixed feed stream of gas and liquid hydrocarbon components enters a reservoir formed between the lower end of the reactor and a conical screen supporting the lower end of a catalyst bed. A wall across the vessel divides the reservoir into a lower surge chamber for receiving the mixed feed and an upper plenum chamber for separating the components into alternate feed rings of gas and hydrocarbon liquid under the conical screen. The mixed feed enters the plenum chamber through a plurality of tubes extending downwardly from the wall to the same depth in the surge chamber that prevents establishing preferential paths for gas to independently enter the plenum chamber. Excessive separation of the gas and liquid components from the mixed feed in the plenum chamber is prevented by use of a plurality of concentric baffles abutting the underside of the conical screen and which are closely spaced apart only sufficient to create adjacent and alternate feed rings of gas and liquid. The depth of the lower end of each baffle is intermediate the depth of the two radially adjacent concentric baffles.Catalyst is continuously or periodically added to, or removed from, the vessel through tubing and a full-bore valve having uniform diameters throughout their lengths to maintain laminar flow of catalyst to or from a pressurizable hopper vessel.

摘要： Applicable to a multiple-stage catalytic reaction system, in which the plurality of stages assume a side-by-side configuration, and in each of which the catalyst particles are movable via gravity-flow, the present inventive concept affords the controlled transport of catalyst particles from one reaction stage, or zone, to another. The system is especially adaptable to be utilized in a multitude of high-pressure processes for the catalytic conversion of hydrocarbonaceous material, in which processes deactivated catalyst particles are either regenerated, or discarded for disposal or, ultimate recovery of the catalytically active metallic components.

摘要： This invention makes possible substantially continuous flow of uniformly distributed hydrogen and hydrocarbon liquid across a densely packed catalyst bed to fill substantially the entire volume of a reactor vessel by introducing the fluids as alternate annular rings of gas and liquid (i.e. a mixture of liquid hydrocarbon and a hydrogen-containing gas) at a rate insufficient to levitate or ebullate the catalyst bed. Catalyst are selected by density, shape and size at a design feed rate of liquids and gas to prevent ebullation of the packed bed at the design feed rates. Catalysts are selected by measuring bed expansion, such as in a large pilot plant run, with hydrocarbon, hydrogen, and catalyst at the design pressures and flow velocities. The liquid and gas components of the feed flow into the bed in alternate annular rings across the full area of the bed. At the desired flow rate, such catalyst continually flows in a plug-like manner downwardly through the reactor vessel by introducing fresh catalyst at the top of the catalyst bed by laminarly flowing such catalyst in a liquid stream on a periodic or semicontinuous basis. Catalyst is similarly removed by laminarly flowing catalyst particles in a liquid stream out of the bottom of the catalyst bed.

摘要： A radial flow reactor design which allows the maintenance of a temperature profile along the height of a catalyst bed which descends through the reactor by gravity flow. Two feed inlet conduits are provided on the inlet side of the annular catalyst bed, with the inlets being divided by a porous flow control and distribution means. The inlet streams have different temperatures and the distribution means produces a changing admixture rate between the two streams along the bed. A preferred form of the distribution means is an open-topped cone located within the centerpipe of the reactor.
