Patent number: 10407366Abstract: 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 synthesiType: GrantFiled: January 19, 2016Date of Patent: September 10, 2019Assignee: Evonik Degussa GmbHInventors: Guido Stochniol, Helene Reeker, Stephan Peitz, Dietrich Maschmeyer, Joerg Schallenberg, Horst-Werner Zanthoff, Harald Haeger

Patent number: 10196327Abstract: The invention is concerned with the production of 1-hexene and octenes from ethene. 1-Butene is optionally also to be produced. The problem addressed by the present invention is that of developing a process for producing 1-hexene from ethene by MTHxE etherification to achieve better chemical utilization of the employed carbon atoms. This problem is solved by catalytic retrocleavage of MTHxE into the C6 olefins and the alcohol, reuse of the alcohol in the etherification and reaction of the obtained C6 olefins with ethene to afford C8 olefins. In this way the alcohol is not lost from the process but rather is internally recirculated as a derivatizing agent. The less attractive C6 olefins from the cleavage product are upgraded to octene with further ethene in order to provide a further commercial product.Type: GrantFiled: June 15, 2017Date of Patent: February 5, 2019Assignee: Evonik Degussa GmbHInventors: Guido Stochniol, Helene Reeker, Dietrich Maschmeyer, Stephan Peitz, Jörg Schallenberg

Patent number: 10189755Abstract: The disclosure describes the oligomerization of supercritical ethene. An essential aspect of the invention is that of mixing ethene with an inert medium and setting the conditions in the reaction such that both ethene and the inert medium are supercritical. This is because the solubility for ethene in the inert medium is greater in the supercritical state, such that more ethene is dissolved in the supercritical inert medium than in a liquid solvent. The process regime in the supercritical state therefore enables the use of a much higher proportion of ethene in a homogeneous mixture of ethene and inert medium than is possible on the basis of the thermodynamic solubility restriction in a purely liquid hydrocarbon stream. In this way, the space-time yield is distinctly enhanced. Since a greater amount of ethene can be passed into the reactor, it is possible as a result to better exploit the apparatus volume compared to a liquid phase process. The inert medium used may, for example, be isobutane.Type: GrantFiled: May 25, 2017Date of Patent: January 29, 2019Assignee: Evonik Degussa GmbHInventors: Helene Reeker, Guido Stochniol, Dietrich Maschmeyer, Stephan Peitz, Jörg Schallenberg

Publication number: 20180208538Abstract: The invention relates to a process for preparing an ester mixture, in which an n-butene-containing feed mixture having a composition which changes over time is first oligomerized and then converted by hydroformylation, hydrogenation and esterification to an ester mixture. In this process, an approximation of the actual viscosity of the ester mixture is determined. The problem that it addresses is that of specifying a comparatively simple process which enables conversion of an n-butene with a variable composition over time to an ester mixture having a viscosity which can be kept very substantially constant over a long period even when an inconstant C4 source which delivers fluctuating qualities over this period is utilized. This is achieved through controlled use of a second raw material, namely ethene. It has been found that the viscosity of n-butene-based ester mixtures can be influenced by controlled use of ethene in the preparation of the ester precursors.Type: ApplicationFiled: March 19, 2018Publication date: July 26, 2018Inventors: Helene Reeker, Guido Stochniol, Dietrich Maschmeyer, Horst-Werner Zanthoff, Jörg Schallenberg, Frank Geilen, Katrin Marie Dyballa, Dirk Fridag, Stephan Peitz, Lena Altmann, Robert Franke

Publication number: 20160318829Abstract: 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.Type: ApplicationFiled: December 4, 2014Publication date: November 3, 2016Applicant: Evonik Degussa GmbHInventors: Felix GAERTNER, Guido STOCHNIOL, Joerg SCHALLENBERG, Horst-Werner ZANTHOFF, Oliver Markus BUSCH, Stephan PEITZ, Frank GEILEN, Arne REINSDORF, Natalya PRODAN

Patent number: 9260386Abstract: 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.Type: GrantFiled: June 25, 2013Date of Patent: February 16, 2016Assignee: Evonik Industries AGInventors: Stephan Peitz, Markus Winterberg, Dietrich Maschmeyer, Frank Geilen, Reiner Bukohl, Joerg Schallenberg, Armin Rix, Andreas Wolff, Matthias Leipold
