Abstract: Catalyst is transferred to and from a relatively high pressure moving-bed reactor through pressurized, liquid filled lock hoppers. A vertically segmented lock hopper is first filled with liquid and then raised to the pressure of the reactor and communicated with the reactor to allow equal portions of catalyst to slowly settle into each section of the lock hopper. Rapidly flowing liquid is then passed into the reactor to prevent catalyst from passing from the reactor while the lock hopper is emptied. The transfer method is used on reactors processing a heavy residual oil and the lock hoppers are pressurized with a lighter oil. Advantages include gentle catalyst transfer, ease of lock hopper pressurization and partial washing of the withdrawn catalyst.

Abstract translation: 催化剂通过加压的，液体填充的锁定料斗被转移到相对高压的移动床反应器中和从相对高压的移动床反应器中转移。 首先将垂直分段的封闭料斗填充液体，然后升高到反应器的压力并与反应器连通，以允许相等的催化剂部分缓慢地沉入密封料斗的每个部分。 然后将快速流动的液体进入反应器，以防止催化剂从反应器中通过，同时封闭料斗被排空。 转移方法用于反应器处理重质残余油，并且锁定料斗用较轻油加压。 优点包括温和的催化剂转移，容易锁定料斗加压和部分洗涤所抽出的催化剂。

Abstract: 1,156,749. Ion-exchange. COMMISSARIAT A L'ENERGIE ATOMIQUE and SOC. GRENOBLOISE D'ETUDES & D'APPLI-CATIONS (HYDRAULIQUES SOGREAH. 18 May, 1967 [20 May, 1966], No. 23203/67. Heading B1J. Liquids to be treated by ion-exchange are admitted to a bed at 2 and are discharged from the sand embedded strainer 3. At the end of a period of treatment an injection of driving fluid at 11 forces the exchange up the column discharging solid at 12 and fluid at 14. The column is replenished from reservoir 9 and when the removal of resin stops a suitable state of equilibrium is reached in the chamber 8. The process of treatment is then repeated.

Abstract: An apparatus of hydrocarbon fuel reactors separates and purifies carbon dioxide (CO2). Interconnected fluidized beds are applied in chemical-looping combustion. A multi-stage reduction reaction is processed with iron-based oxygen carriers. Three reduction stages using the iron-based oxygen carriers are accurately and completely controlled. Each of the three stages is separately processed in an individual space. Oxygen in the iron-based oxygen carriers can be fully released. High-purity CO2 is obtained. Hydrogen can be produced as an option. Horizontal connection of three reduction reactors is changed into vertical one. An oxidation reactor is further connected. Thus, the whole structure occupies less area and effectively uses vertical space. Not only small space is effectively used; but also high-volume capacity is obtained. Each of the reactors has better geometry flexibility. The tandem reactor in each layer has less geometric influence and limitation. Therefore, each of the reactors can be resized on its own.

Abstract: One exemplary embodiment can include a slurry hydrocracking process. The process can include combining one or more hydrocarbons and a slurry hydrocracking catalyst as a feed to a slurry hydrocracking reaction zone, fractionating an effluent from the slurry hydrocracking reaction zone, separating the pitch from at least a portion of the slurry hydrocracking catalyst, and recycling the suspension to the slurry hydrocracking reaction zone. The slurry hydrocracking catalyst may include a support. Fractionating the effluent may provide a light vacuum gas oil, a heavy vacuum gas oil, and a mixture comprising a pitch and the slurry hydrocracking catalyst. Generally, the separated slurry hydrocracking catalyst is comprised in a suspension.
