    摘要： An electrochemical conversion method for converting at least a portion of a first mixture comprising hydrocarbon to C2+ unsaturates by repeatedly applying an electric potential difference, V(τ1), to a first electrode of an electrochemical cell during a first time interval τ1; and reducing the electric potential difference, V(τ1), to a second electric potential difference, V(τ2), for a second time interval τ2, wherein τ2≦τ1. The method is beneficial, among other things, for reducing coke formation in the electrochemical production of C2+ unsaturates in an electrochemical cell. Accordingly, a method of reducing coke formation in the electrochemical conversion of such mixtures and a method for electrochemically converting carbon to C2+ unsaturates as well as an apparatus for such methods are also provided.

    摘要： A process for preparing oligomers by continuous oligomerization of butenes is described, wherein a) a feed stream 1) comprising 1-butene and 2-butene in a total concentration of from 10 to 70% by weight and from 10 to 60% by weight of isobutane is reacted until more than 60% by weight of the 1-butene comprised in the feed stream 1 but less than 50% by weight of the 2-butene comprised in feed stream 1 have been converted into oligomers. b) The oligomers obtained in a) are separated off and optionally passed to a further work-up and the remaining residual stream is fed to work-up by distillation. c) Isobutane is separated off by distillation from the residual stream, and d) the isobutane-depleted stream obtained after the work-up by distillation c) is reacted to form oligomers.

    摘要： A processing scheme and system for enhanced light olefin production, particularly for increased relative yield of propylene, involves oxygenate conversion to olefins and subsequent oxygenate conversion effluent stream treatment including dimerization of ethylene to butene and metathesis of butenes and/or hexenes with ethylene. The processing scheme and system may further involve isomerization of at least a portion of 1-butene to 2-butene to produce additional propylene.

    摘要： A process for reacting a first component with itself or a second component to produce a third component in which a first material comprising a first component or said first component and a second component is fed to divided wall column having a catalytic distillation structure in at least one of the separate vertical sections of the divided wall column where concurrently: (1) a first component alone or with a second component is contacted with a catalytic distillation structure in a distillation reaction zone thereby catalytically reacting at least a portion of the first component with itself or with the second component to form a product and (2) a first mixture comprising the first component and the product or the first component, the second component and the product; and withdrawing the product from the distillation column reactor; while within the column concurrently with the catalytic reaction and fractionation a second mixture is fractionated, which contains the first component and the product or first and second components (if a second component is present) and the product in a parallel and separate distillation non reaction zone to fractionate the product and withdrawing the product from said distillation non reaction zone. For example, tertiary amyl methyl ether may be prepared by reacting methanol with isoamylene in a C5 stream utilizing a distillation column reactor wherein the distillation column reactor comprises one side of a divided wall column. On one side the product, tertiary amyl methyl ether, is separated from the unreacted methanol and C5's and on the other side the remaining isoamylenes are reacted with methanol and a separation of the tertiary amyl methyl ether and C5's from the methanol/C5 azeotrope is effected.
