    • A hydroprocessing process for removing impurities from a feed comprising a hydrocarbonaceous liquid comprises at least two cocurrent, upflow hydroprocessing reaction stages and a non-catalytic, vapor-liquid contacting stage. The reaction and contacting stages may all be in the same reactor vessel. The feed and a hydrogen treat gas are passed up into a catalyst bed which comprises the first reaction stage, which produces a partially hydroprocessed liquid and vapor effluent. This first stage vapor is passed up into the contacting stage in which it contacts a hydrocarbonaceous liquid which reduces the vapor impurity content. The impurity-enriched contacting liquid passes down and mixes with the first stage liquid effluent. The combined effluents and hydrogen are passed up into the second reaction stage to form a processed product liquid and hydrogen-containing vapor effluent. This second reaction stage vapor effluent is passed up into the first stage to provide at least a portion of the hydrogen for the first stage reaction. Additional product liquid may be recovered by cooling the contacting and condensing the purified contacting stage vapor effluent.
    • 用于从包含烃液体的进料中除去杂质的加氢处理方法包括至少两个并流,向上加氢处理反应阶段和非催化气液接触阶段。 反应和接触阶段都可以在同一反应容器中。 进料和氢气处理气体被送入催化剂床,催化剂床包括第一反应段,其产生部分加氢处理的液体和蒸气流出物。 该第一级蒸气通入其接触阶段,在该阶段中,其接触含烃液体,这降低了蒸气杂质含量。 杂质富集的接触液体向下流动并与第一级液体流出物混合。 将合并的废水和氢气输送到第二反应阶段以形成加工产物液体和含氢蒸汽流出物。 将该第二反应段蒸气流出物向上流入第一阶段以提供用于第一阶段反应的氢的至少一部分。 可以通过冷却接触并冷凝纯化的接触级蒸气流出物来回收附加的产物液体。

    • A process for automatically providing for periodic surge flow or liquid slugs in the catalyst bed to insure that the catalyst is periodically fully wetted. Therefore, before dry spots develop in the bed and some catalyst particles are deprived of the liquid reactants, the aforesaid liquid pulse or slug will rewet the catalyst. This desired periodic introduction of a liquid slug through a catalyst bed is accomplished by the provision of a plurality of automatically actuating and operating siphon means disposed and distributed across the area of the distributor tray means within the reactor.
    • 一种用于在催化剂床中自动提供周期性浪涌流动或液体段的过程,以确保催化剂周期性地完全润湿。 因此,在床上发生干斑之前,一些催化剂颗粒被剥夺了液体反应物,所以前述的液体脉冲或细粒将再润湿催化剂。 通过设置多个自动致动和操作的虹吸装置来实现液体塞通过催化剂床的周期性引入,该多个自动启动和操作的虹吸装置设置并分布在反应器内的分配器托盘装置的区域上。

    • The invention is for a fixed bed reactor with two phase gas and liquid flow. The reactor has at least one auxiliary bed of solid particles disposed above the main bed of solid particles. The auxiliary bed has a liquid bypass comprised of hollow tubing extending through the auxiliary bed. Liquid receptacles provide a liquid seal above the liquid bypasses, thereby preventing gas from bypassing along with the liquid. The liquid spilled from the flow receptacles seeks its lowest level and flows through the auxiliary bed. The tubing provides a bypass first for the liquid and later for both the liquid and gas when the auxiliary bed becomes fouled and the liquid seal is thereby broken. This feed arrangement allows for a low pressure drop bypassing of the auxiliary bed, when the auxiliary bed becomes fouled and clogged. The invention is also applicable to other apparatuses which use a flow arrangement similar to fixed bed reactors, but which do not necessarily utilize a chemical reaction. One example of such apparatus is a packed absorption tower having co-current downflow of gas and liquid.
    • 本发明是用于具有两相气体和液体流的固定床反应器。 反应器具有至少一个固体颗粒辅助床,其设置在固体颗粒主床上方。 辅助床具有包括延伸​​穿过辅助床的中空管的液体旁路。 液体容器在液体旁路之上提供液体密封,从而防止气体与液体一起旁路。 从流动容器溢出的液体寻求其最低水平并流过辅助床。 当辅助床被污染并且液体密封件被破坏时,管道首先为液体提供旁路并且随后用于液体和气体。 当辅助床被弄脏并堵塞时,该馈送装置允许辅助床的低压降旁路。 本发明也适用于使用类似于固定床反应器但不一定利用化学反应的流动布置的其它装置。 这种装置的一个实例是具有气流和液体的并流下流的填充吸收塔。
