    • The invention relates to a process for producing premium gasoline from olefinic C.sub.4 cuts containing 1- and 2-butenes and isobutene, the process consisting of converting at least 97% of the total isobutene content of the charge and at least the major portion of the 1- and 2-butenes thereof to C.sub.4 hyrocarbons dimers and trimers without producing substantial amounts of kerosene, said process being characterized in that, in a first step, the olefinic C.sub.4 cut is treated in a first polymerization catalytic zone so as to convert at least 80% of the isobutene to isobutene dimers and trimers and to convert at most 45% of the mixture of 1- and 2-butenes to dimers and trimers thereof, in that, subsequently, the effluent from said first catalytic polymerization zone is fractionated so as to recover, on the one hand, from the column bottom, essentially the C.sub.4 olefinic hydrocarbon dimers and trimers and, on the other hand, from the top of the column, a mixture containing the major part of the isobutene and 1- and 2-butenes not converted in said first catalytic polymerization zone, said mixture being, during a second step, at least partly fed to a second catalytic polymerization zone so as to convert (a) substantially the total amount of isobutene to isobutene dimers and trimers in said second zone and (b) at least 50% of the 1- and 2-butenes, supplied to said second zone to n-butenes dimers and trimers.
    • 本发明涉及从含有1-和2-丁烯和异丁烯的烯烃C4馏分产生优质汽油的方法,该方法包括将至少97%的电荷的异丁烯含量和至少大部分的1 - 和2-丁烯,其不产生大量的煤油,所述方法的特征在于,在第一步骤中,将烯烃C4馏分在第一聚合催化剂区域中处理以使其转化为至少80 %异丁烯与异丁烯二聚体和三聚体的比例,并将至多45%的1-和2-丁烯的混合物转化为二聚体和三聚体,因为随后将来自所述第一催化聚合区的流出物分馏,以便 一方面从塔底回收,基本上是C4烯烃二聚体和三聚体,另一方面从塔顶回收含有主要部分异丁烯的混合物 并且在所述第一催化聚合区中未转化的1-和2-丁烯,所述混合物在第二步骤期间至少部分地进料到第二催化聚合区,从而将(a)基本上将异丁烯的总量转化为异丁烯 所述第二区域中的二聚体和三聚体,和(b)至少50%的1-和2-丁烯,被供应到所述第二区域以形成正丁烯二聚体和三聚体。

    • Highly pure 1-butene and premium gasoline are obtained by(a) subjecting a C.sub.4 olefinic cut to a polymerization-disproportionation to partly convert the isobutene thereof to a gasoline which, in turn, by partial disproportionation, yields a jet fuel base and butenes,(b) fractionating the effluent from step (a) to a mixture (.alpha.) of gasoline and jet fuel base and to a fraction (.beta.) containing isobutane, n-butane, butenes, a small amount of isobutene and a minor amount of butadiene,(c) selectively polymerizing fraction (.beta.) to convert more than 90% of the isobutene thereof to gasoline,(d) fractionating the polymerized fraction (.beta.) to a gasoline cut (.gamma.) containing isobutene dimers and trimers and to a fraction (.delta.) containing isobutane, n-butane and butenes,(e) selectively hydrogenating the fraction (.delta.),(f) removing isobutane from the hydrogenated fraction (.delta.) and(g) fractionating the deisobutanized hydrogenated fraction (.delta.) to obtain a fraction containing at least 99% of 1-butene, the mixture (.alpha.) being admixed with the cut (.gamma.).
    • 通过以下方法获得高纯度的1-丁烯和优质汽油:(a)使C4烯烃切割物进行聚合歧化,将其异丁烯部分转化成汽油,然后汽油通过部分歧化产生喷气燃料基体和丁烯, (b)将来自步骤(a)的流出物分馏成汽油和喷气燃料基料的混合物(α)和含有异丁烷,正丁烷,丁烯,少量异丁烯和少量丁二烯的馏分(β) ,(c)选择性地聚合馏分(β)以将其超过90%的异丁烯转化成汽油,(d)将聚合馏分(β)分馏成含有异丁烯二聚体和三聚体的汽油馏分(γ) (e)选择性氢化馏分(δ),(f)从氢化馏分(delta)中除去异丁烷,和(g)分离除异丁氢化氢化馏分(delta)以获得af 反应物含有至少99%的1-丁烯,混合物(α)与切割(γ)混合。
