  • Patent number: 10647630
    Abstract: A process for the combined preparation of at least butene and octene from ethane, proceeds by a) providing an inert solvent having a boiling point or boiling range below the boiling point of butene; b) providing a first feed mixture comprising at least the inert solvent and ethene dissolved therein; c) converting the first feed mixture in a first synthesis; d) in the first synthesis, oligomerizing at least a portion of the ethene present in the first feed mixture in the presence of a first heterogeneous catalyst and in the presence of the inert solvent to obtain a first reaction mixture comprising at least the inert solvent, butene, hexene and octene; e) working-up of the first reaction mixture and/or a substance stream based thereon into a low boiler fraction comprising the inert solvent, at least one C4-fraction comprising butenes, a C6-fraction comprising hexenes, a C8-fraction comprising octenes and into a C8+-fraction comprising hydrocarbons having more than eight carbon atoms; f) using at least a portio

  • Patent number: 10407366
    Abstract: A process for the combined preparation of a butene and an octene from ethene, proceeds by: a) providing a solvent having a boiling point or boiling range above the boiling points of the butenes and below the boiling points of the octenes and wherein the solvent is an inert solvent or is hexene alone or is hexene admixed with pentane or hexane or heptane or is a mixture of pentane, hexane, and heptane; b) providing a first feed mixture containing at least the solvent and ethene dissolved therein; c) providing a second feed mixture containing at least hexene, the solvent and also ethene dissolved in the solvent and/or in the hexene; d) transferring the first feed mixture into a first synthesis and the second feed mixture into a second synthesis, wherein the first and second syntheses are physically separated from one another; e) oligomerizing of at least part of the ethene present in the first feed mixture in the presence of a first heterogeneous catalyst and in the presence of the solvent in the first synthesi

  • Patent number: 9624143
    Abstract: The invention relates to a method for producing linear butenes from methanol. The problem addressed is that of specifying such a method in which the methanol used is converted, to the largest possible extent, into butenes. The problem is solved by combining a methanol-to-propylene process with a metathesis reaction by means of which the propene obtained from the methanol is converted into linear butenes.

  • Publication number: 20160318829
    Abstract: The invention relates to a process for preparing 1,3-butadiene by heterogeneously catalysed oxidative dehydrogenation of n-butene, in which a butene mixture comprising at least 2-butene is provided. The problem that it addresses is that of specifying a process for economically viable preparation of 1,3-butadiene on the industrial scale, which is provided with a butene mixture as raw material, wherein the 1-butene content is comparatively low compared to the 2-butene content thereof, and in which the ratio of 1-butene to 2-butene is subject to variation. This problem is solved by a two-stage process in which, in a first stage, the butene mixture provided is subjected to a heterogeneously catalysed isomerization to obtain an at least partly isomerized butene mixture, and in which the at least partly isomerized butene mixture obtained in the first stage is then subjected, in a second stage, to oxidative dehydrogenation. The two-stage process leads to higher butadiene yields compared to the one-stage process.

  • Patent number: 9260386
    Abstract: The invention relates to a method for the thioetherification of mercaptanes with polyunsaturated hydrocarbons, carried out in a reactor with the addition of hydrogen, using a heterogenic catalyst and in the presence of 1-butene. The aim of the invention is to develop such a method to the extent that the creation of value from the C4 raw material stream is increased. Said aim is achieved in that the hydrogen is added to the reaction in such a manner that the molar ratio of hydrogen to polyunsaturated hydrocarbons is no more than one.
