    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: A reactor apparatus and related method for controlling at least one process variable in a circulating fluid bed oxygenates to olefins reactor system comprising a riser are provided. The process variable is selected from at least one of (i) space velocity, (ii) average reaction temperature, (iii) conversion of reactant, and (iv) average coke level on catalyst. Typically, a corresponding set point for at least one process variable is selected from (1) reactant feed rate, (2) feed enthalpy, (3) reactor temperature-related function, e.g., mid-temperature or rate of temperature rise along a portion of the reactor, and (4) catalyst hold-up in the riser of the reactor. A corresponding manipulated variable is selected from (a) feed flow control valve(s), (b) feed preheat rate, (c) activity of the catalyst in the reactor, and (d) amount of catalyst in the reaction zone. The combination of measured and manipulated variables described here allows for smooth, stable control of the reactor at the optimum performance level.

    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. A 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. Hydrogen is separated from at least one of the first effluent stream and the tail gas stream and at least part of the hydrogen is recycled as part of the fuel for the regeneration stage of the cyclic steam reformer.

    摘要: The present invention is directed to a hydrocarbon conversion apparatus. The apparatus comprises the following: a plurality of riser reactors, each of the riser reactors having a first end into which a catalyst can be fed and a second end through which the catalyst can exit the riser reactor; a separation zone into which the second ends of the riser reactors extend, the separation zone being provided to separate the catalyst from products of a reaction conducted in the hydrocarbon conversion apparatus; and at least one catalyst return in fluid communication with the separation zone and the first ends of the riser reactors, the catalyst return being provided to transfer the catalyst from the separation zone to the first ends of the riser reactors.
