    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： 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 is directed to a hydrocarbon conversion apparatus and process. The apparatus comprises the following: a plurality of riser reactors, each having a first end into which a catalyst is fed, a second end through which the catalyst can exit, and optionally a center axis extending therebetween. The apparatus also includes a separation zone having a plurality of inlets, each inlet not being oriented along the center axes of the riser reactors, the separation zone being provided to separate the catalyst from products of a reaction conducted in the hydrocarbon conversion apparatus. A plurality of deviating members are also provided, each deviating member being in fluid communication between the second end of a respective riser reactor and a respective inlet of the separation zone. The apparatus also includes a catalyst retention zone provided to contain catalyst, which is fed to the riser reactors. A catalyst return is in fluid communication between the separation zone and the catalyst retention zone.

    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.

    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.
