    摘要: A process for producing methanol is described in which a hydrocarbon is steam reformed in a reforming zone, and during the reforming stage, of a cyclic steam reformer having a reforming stage and a regeneration stage, the steam reforming being conducted under conditions effective to produce a first effluent stream containing synthesis gas. Fuel and an oxygen-containing gas are combusted in the regeneration stage of the reformer so as to reheat the reforming zone to a temperature sufficient for the reforming stage and generate a flue gas. At least part of the first effluent stream is contacted with a methanol synthesis catalyst under conditions effective to convert synthesis gas to methanol and form a methanol-containing stream and a tail gas stream comprising unreacted carbon monoxide and hydrogen. At least part of the tail gas stream is recycled as fuel for the regeneration stage of the cyclic steam reformer.

    摘要: The present invention provides a process for producing synthesis gas blends which are especially suitable for conversion either into oxygenates such as methanol or into Fischer-Tropsch liquids. Such a process involves reforming of two separate gaseous hydrocarbon feedstreams (formed, for example, by dividing a natural gas feedstock) in a steam-reforming unit and an oxygen-blown reforming unit, respectively. The syngas effluent from each reforming unit is then combined, after appropriate pressure adjustments, to realize a synthesis gas blend containing selected amounts and ratios of H2, CO and CO2. In further invention embodiments, processes are provided for converting the resulting syngas blends into oxygenates or Fischer-Tropsch hydrocarbons. Further conversion of the oxygenates so produced into light olefins also constitutes part of this invention.

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: 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.

    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.
