    摘要: The invention concerns a process for the separation of a mixture comprising ethylene, 1-butene, alpha-olefins containing at least 6 carbon atoms per molecule and possibly heavier hydrocarbon products, the ethylene content of the mixture being in the range 30% to 70% by weight, in which separation is effected in a distillation zone to obtain an overhead fraction comprising the major portion of the ethylene present in the mixture and between 0% and 100% by weight of the 1-butene present in the mixture, the process being characterized in that the zone is also supplied with supplemental 1-butene in an amount in the range 1 to 40 times the quantity (by weight) of 1-butene present in the mixture. In a preferred implementation of the process of the invention, the mixture originates form a homogenous liquid phase ethylene oligomerisation zone.

    摘要: Process for producing a hydrocarbon cut of high octane number by etherification of an olefin-containing hydrocarbon cut.The olefinic cut, to which methanol is added, passes into an etherification reactor (1) wherefrom are separated (3) a bottom product (15) containing ethers, and a top product (14) containing residual methanol and unreacted light olefins. This top product passes into an etherification reactor (2) and then is washed with water (8).The top product is finally admixed with the bottom product.The so-obtained motor-fuel has a higher octane number than that of the initial hydrocarbon cut.
