    • A reactor for the upgrade of heavy oil feedstock, i.e., in which a multi-phase mixture, including gas, a slurry catalyst, and volatile liquid, is to be conducted. The reactor includes a reaction chamber having a substantially unencumbered center portion through which the multi-phase mixture is conducted upwardly. In one embodiment, the downcomer includes a transport section having an interior comprised of inner and outer regions separated horizontally by a vertical barrier, and a baffle structure disposed on an inner surface of the barrier. In another embodiment, the reactor comprises a downcomer having an upper degassing section which includes a frusto-conical upper surface. The multi-phase mixture is caused to flow along the surface in a downward helical path, such that heavier components are centrifugally urged outwardly, and lighter components, e.g., gas, migrate inwardly. In one embodiment, the reactor comprises a distributor device disposed within for distributing the multi-phase mixture therein. The distributor device includes a first pipe adapted for conducting a gas phase, and including first discharge ports, a second pipe adapted for conducting a slurry or a liquid phase, and including second discharge ports, and a plurality of nozzles.
    • 用于提升重油原料的反应器,即其中要进行多相混合物(包括气体,浆料催化剂和挥发性液体)的反应器。 该反应器包括反应室,该反应室具有基本上不受阻碍的中心部分,多相混合物通过该中心部分向上传导。 在一个实施例中,降液管包括具有由通过竖直隔板水平分隔的内部区域和外部区域的内部的输送部分以及设置在隔板的内表面上的挡板结构。 在另一个实施方案中,反应器包括具有上脱气部分的降液管,该上脱气部分包括截头圆锥形上表面。 使多相混合物沿向下的螺旋路径沿表面流动,使得较重的组分被离心地向外推动,并且较轻的组分例如气体向内移动。 在一个实施方案中,反应器包括布置在其中的分配器装置,用于在其中分配多相混合物。 分配器装置包括适于引导气相的第一管道和多个喷嘴,所述第一管道包括第一排放端口,适于传导浆液或液相的第二管道,并且包括第二排放端口。
