摘要： A process for the production of tertiary ethers, including: feeding a hydrocarbon stream comprising isoolefins and propionitrile to a distillation column reactor system containing at least one etherification reaction zone; feeding a C2 to C6 monoalcohol or mixture thereof to the distillation column reactor; concurrently in the distillation column reactor system: reacting a portion of the isoolefins with a portion of the alcohols to form a tertiary ether; and separating the tertiary ether from unreacted isoolefins; withdrawing the tertiary ether and propionitrile from the distillation column reactor system as a bottoms; withdrawing the unreacted isoolefins from the distillation column reactor system as an overheads; and operating the distillation column reactor system such that the etherification reaction zone is substantially free of propionitrile.

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.

摘要： A process for the hydrodesulfurization of a diesel boiling range petroleum fraction wherein the hydrodesulfurization is carried out concurrently with a fractional distillation in a distillation column reactor containing a catalyst bed. The diesel is fed above the catalyst bed and hydrogen is fed below the bed. The bottoms from the distillation column reactor is then separated by fractional distillation to remove a bottoms containing most of the unconverted sulfur.

摘要： A process for the production of low benzene content gasoline is disclosed wherein a full boiling range naphtha is fractionated to produce a light naphtha, a medium naphtha and a heavy naphtha. The benzene is contained in the medium naphtha and this stream is subjected to hydrogenation to convert the benzene to cyclohexane which may be isomerized to improve the octane. The valuable olefins are removed in the light naphtha and the valuable heavier aromatics (toluene and xylenes) are removed in the heavy naphtha. In a preferred embodiment all of the reactions are carried out in distillation column reactors.
