Abstract: Processes for shutting down a hydroprocessing reactor and for removing catalyst from the reactor may comprise shutting off hydrocarbon feed to the reactor, stripping hydrocarbons from the catalyst, cooling the reactor to a first threshold reactor temperature, purging the reactor with N2 gas, introducing water into the reactor, and dumping the catalyst from the reactor, wherein the first threshold reactor temperature may be substantially greater than 200° F. In an embodiment, the water may be introduced into the reactor via a quench gas distribution system when the reactor is at a second threshold reactor temperature not greater than 200° F. to cool the reactor to a third threshold reactor temperature not greater than 120° F.
Abstract translation: 关闭加氢处理反应器和从反应器中除去催化剂的方法可包括：将烃进料切断至反应器，从催化剂中汽提烃，将反应器冷却至第一阈值反应器温度，用N 2气体吹扫反应器，将水引入 反应器和从反应器中倾倒催化剂，其中第一阈值反应器温度可以基本上大于200°F。在一个实施方案中，当反应器处于一个或多个反应器时，可以通过骤冷气体分配系统将水引入反应器 第二阈值反应器温度不大于200°F，以将反应器冷却至不大于120°F的第三阈值反应器温度。

Abstract: A process is provided for removing a heavy polynuclear aromatic (HPNA) compound from a hydrocarbon oil. The process includes contacting the hydrocarbon oil containing the HPNA compound with a lean hydrocarbon-immiscible liquid stream to produce a mixture comprising the hydrocarbon oil and a rich hydrocarbon-immiscible liquid containing the HPNA compound; and separating the mixture to produce a hydrocarbon oil effluent having a reduced level of the HPNA compound and a hydrocarbon-immiscible liquid effluent containing the HPNA compound. The hydrocarbon-immiscible liquid can be a halometallate ionic liquid, a liquid coordination complex, or a combination thereof.
