摘要： A method and system for the selective removal of CO 2 and/or H 2 S from a gaseous stream containing one or more acid gases. In particular, a system and method for separating CO 2 and/or H 2 S from a gas mixture containing an acid gas using an absorbent solution and one or more ejector venturi nozzles in flow communication with one or more absorbent contactors. The method involves contacting a gas mixture containing at least one acid gas with the absorbent solution under conditions sufficient to cause absorption of at least a portion of said acid gas. The absorbent contactors operate in co-current flow and are arranged in a counter-current configuration to increase the driving force for mass transfer. Monoliths can be used that operate in a Taylor flow or slug flow regime. The absorbent solution is treated under conditions sufficient to cause desorption of at least a portion of the acid gas.

摘要： The invention is directed to a fixed bed reactor (51) having one or more bypass devices for extending the operating life of the reactor. The bypass devices may be placed within a fixed catalyst bed (56) to partition the bed (56) into a first top bed (58) and a second virtual bed (59). One embodiment of the bypass device allows a fluid feedstock to bypass the first top bed (58) of the fixed catalyst bed (56) as it fouls and enters the second virtual bed (59) under conditions that promote depositing any foulants contained in the bypass flow on the top surface of the second virtual bed (59) rather than in the interstices of the second virtual bed (59). Another embodiment relates to a multi-tier bypass that allows a fluid feedstock to bypass successive layers of a fixed bed as they foul. The invention also relates to an improved fixed bed reactor comprising the inventive bypass device and a method for extending the operating life of a fixed bed reactor that employs the inventive bypass device.
摘要翻译：本发明涉及具有一个或多个旁路装置的固定床反应器（51），用于延长反应器的使用寿命。旁路装置可以放置在固定的催化剂床（56）内以将床（56）分隔成第一顶床（58）和第二虚拟床（59）。旁路装置的一个实施例允许流体原料绕其固定的催化剂床（56）的第一顶床（58），因为它在有助于沉积包含在旁路中的任何污垢的条件下被破坏并进入第二虚拟床（59）在第二虚拟床（59）的顶表面上而不是在第二虚拟床（59）的间隙中流动。另一个实施例涉及一种多层旁路，其允许流体原料在污染时绕过固定床的连续层。本发明还涉及一种改进的固定床反应器，其包括本发明的旁路装置和用于延长采用本发明旁路装置的固定床反应器的使用寿命的方法。

摘要： Refractory or hard sulfur found in a hydrocarbon stream containing refractory sulfur heterocycle compounds, particularly those exhibiting steric hindrance, is removed from the stream by contacting it with a sodium reagent comprising a sodium component, having free sodium, supported on a solid support component. If the hydrocarbon stream contains more labile or easy sulfur, then it is treated, typically by hydrodesulfurization, to remove at least most of the labile sulfur before it is contacted with the sodium reagent. This is useful for bringing the sulfur level of middle distillate fuel streams, such as diesel and jet fuel fractions, down to a level of less than 10 wppm, employing conventional hydrodesulfurizing catalysts and conditions.

摘要： A distillate fuel feed is hydrotreated to remove heteroatoms and then separated into light and heavy hydrotreated fractions, with the heavy fraction catalytically dewaxed to improve low temperature properties. The hydrotreating and dewaxing are conducted in separate stages, which may be in the same reactor vessel. Fresh hydrogen may be passed into the dewaxing stage, with the dewaxing stage gaseous effluent then passed into the hydrotreating stage to provide hydrogen for the hydrotreating. Existing hydrotreating reaction vessels and facilities may be retrofitted to add one or more dewaxing stages.

摘要： Systems and methods are provided for conversion of methane and/or other hydrocarbons to hydrogen by pyrolysis while reducing or minimizing production of carbon oxides. The heating of the pyrolysis environment can be performed at least in part by using electrical heating within a first stage to heat the coke particles to a desired pyrolysis temperature. This electrical heating can be performed in a hydrogen-rich environment in order to reduce, minimize, or eliminate formation of coke on the surfaces of the electrical heater. The heated coke particles can then be transferred to a second stage for contact with a methane-containing feed, such as a natural gas feed. Depending on the configuration, pyrolysis of methane can potentially occur in both the first stage and second stage. In some aspects, the hydrogen-rich environment in the first stage is formed by passing the partially converted effluent from the second stage into the first stage. In such aspects, the partially converted effluent from the second stage can have an H2 content of 60 vol% or more, or 70 vol% or more, or 80 vol% or more, such as up to 99 vol% or possibly still higher.
