Abstract: 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.

Abstract: On-stream catalyst replacement hydroprocessing method wherein an upstream mixture of hydrogen and hydrocarbon liquid counter flows through a downwardly moving bed of hydroprocessing catalyst in a reactor vessel. The mixed feed stream of hydrogen and liquid hydrocarbon components enters a surge zone between the lower end of the reactor and a plenum zone to form a common pool under a conical support for the lower end of the downflowing catalyst bed. The mixed feed enters the plenum chamber through a plurality of passageways extending downwardly from the plenum zone to the same depth adjacent the lower end of the surge zone so that the liquid component normally prevents hydrogen from establishing independent paths before entering the plenum zone. Separation of the hydrogen and hydrocarbon liquid components from the mixed feed is thus assured to occur in the plenum zone directly below the pervious conical support to form a plurality of stepped concentric local reservoir rings under the conical support.

Abstract: 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.
