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： 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. Intake for such flow is out of direct contact with the stream of gas flowing through the bed and the flow path is substantially constant in cross-sectional area and greater in diameter by several times than the diameter of the catalyst particles. The catalyst of this invention produces a plug-flowing substantially packed bed of hydroprocessing catalyst which occupies at least about 75% by volume of the reactor volume.

摘要： 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. Such rings are spaced apart sufficiently to create adjacent and alternate separate feed rings of hydrogen and hydrocarbon liquid. The depth of the lower end of each ring is intermediate the depth of the two radially adjacent concentric rings to maintain uniform feed of hydrogen and hydrocarbon liquid across the full cross-sectional area of the downflowing catalyst particles.

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： A process is provided for converting a hydrocarbon feedstock comprising the steps of introducing the hydrocarbon feedstock to a first hydroconversion zone at superatmospheric pressure and at a temperature between about 450.degree. F. and about 850.degree. F. in the presence of hydrogen, the hydrogen flowing in a countercurrent relationship to the hydrocarbon feedstock, to form a hydrogen-rich vapor effluent and a hydrocarbon-rich liquid effluent; reacting the hydrogen-rich vapor effluent in a second hydroconversion zone to form a converted vapor effluent; and introducing a portion of the hydrocarbon-rich liquid effluent to the second hydroconversion zone in countercurrent relationship to the hydrogen-rich vapor effluent. By recycling to the second hydroconversion zone a stream having sufficiently high boiling range that it remains a liquid, a greater range of operating conditions are possible in the second hydroconversion zone, thus allowing for higher conversions and product yields.

摘要翻译： 提供了一种用于转化烃原料的方法，包括以下步骤：在氢气存在下，在超大气压和约450°F至约850°F的温度下将烃原料引入第一加氢转化区，氢气流动 与烃原料逆流关系，形成富氢蒸汽流出物和富烃液体流出物; 使富氢蒸汽流出物在第二加氢转化区中反应以形成转化的蒸汽流出物; 并将富含烃的液体流出物的一部分与富氢蒸气流出物逆流地引入第二加氢转化区。 通过再循环到第二加氢转化区，具有足够高沸点范围的物流，其保持液体，在第二加氢转化区可能有更大范围的操作条件，从而允许更高的转化率和产物产率。
