    摘要: The present invention is directed to a method and system for integrating a catalyst regeneration system with a plurality of hydrocarbon conversion apparatuses, preferably, a plurality of multiple riser reactor units. One embodiment of the present invention is a reactor system including a plurality of reactor units, at least one reactor unit preferably comprising a plurality of riser reactors. The system also includes a regenerator for converting an at least partially deactivated catalyst to a regenerated catalyst. A first conduit system transfers the at least partially deactivated catalyst from the reactor units to the regenerator, and a second conduit system transfers regenerating catalysts from the regenerator to the plurality of reactor units. Optionally, catalysts from a plurality of hydrocarbon conversion apparatuses may be directed to a single stripping unit and/or a single regeneration unit.

    摘要: The invention relates to olefin oligomerization methods and methods for reducing/inhibiting fouling in olefin oligomerization reactions comprising: contacting, in an oligomerization reactor (e.g., under oligomerization conditions), an alpha-olefin feed, a catalyst having an olefin selectivity of at least 90 mol % to a desired oligomerization product, a polymer anti-foulant, and optionally a diluent; selectively producing an effluent comprising the desired oligomerization product, unreacted olefin, and alpha-olefin-based polymer byproduct that causes fouling. The amount of polymer anti-foulant can be chosen to limit fouling to ≦20 g/kg desired oligomerization product, to remediate ≧3 grams fouled polymer/kg desired oligomerization product, and/or to reduce/inhibit polymer fouling by ≧10% over a selective oligomerization with substantially no added polymer anti-foulant. Advantageously, desired oligomerization product so obtained can also be polymerized/copolymerized with an alpha-olefin such as ethylene.

    摘要: The present invention relates to a method for preparing olefin comonomers from ethylene. The comonomer generated can be used in a subsequent process, such as a polyethylene polymerization reactor. The comonomer generated can be transported, optionally without isolation or storage, to a polyethylene polymerization reactor. One method includes the steps of: feeding ethylene and a catalyst in a solvent/diluent to one or more comonomer synthesis reactors; reacting the ethylene and the catalyst under reaction conditions sufficient to produce an effluent comprising a desired comonomer; forming a gas stream comprising unreacted ethylene, and a liquid/bottoms stream comprising the comonomer, optionally by passing the effluent to one or more downstream gas/liquid phase separators; and purifying at least a portion of said liquid/bottoms stream by removing at least one of solid polymer, catalyst, and undesirable olefins therefrom.

    摘要: The present invention relates to processes for forming mixed alcohols containing methanol and ethanol. The mixed alcohol can then be used as a feedstock for an oxygenate-to-olefin reaction system for conversion thereof to ethylene, propylene, and the like. In addition, the olefins produced by the oxygenate-to-olefin reaction can then be used as monomers for a polymerization of olefin-containing polymers and/or oligomers.

    摘要: In a process for converting methane to syngas and aromatic hydrocarbons, a feed containing methane is contacted with a dehydrocyclization catalyst under conditions effective to convert said methane to aromatic hydrocarbons and produce a first effluent comprising aromatic hydrocarbons and H2, wherein said first effluent comprises at least 5 wt % more aromatic hydrocarbons than said feed. At least part of the H2 from said first effluent is then reacted with an oxygen-containing species, such as carbon dioxide, to produce a second effluent having an increased H2 and CO content compared with said first effluent.

    摘要: This invention is directed to a process for making a methanol product from a synthesis gas (syngas) feed using a fluid bed reactor. Internal reactor heat transfer is balanced between feed preheat and catalyst bed temperature using appropriate backmixing of feed and catalyst. Backmixing can be appropriately controlled using a number of control points, including any one or more of superficial gas velocity, catalyst density in the reactor, reactor height to diameter ratio (preferably at least in the region of the dense catalyst bed), and catalyst particle size.

    摘要: This invention is directed to a process for producing methanol. The methanol product that is produced according to this invention is achieved with a high conversion of synthesis gas. The high conversion of synthesis gas is achieved by flowing a liquid layer across a plurality of catalyst beds countercurrent to the gas flow. The gas containing methanol product exiting each bed flows through the liquid layer. The liquid acts to extract methanol from the gas, as well as cool the gas.
