Patent number: 10081580Abstract: The present invention relates to a process for preparing cyclohexane by isomerizing a hydrocarbon mixture (HM1) comprising methylcyclopentane (MCP) in the presence of a catalyst. The catalyst is preferably an acidic ionic liquid. The starting material used is a stream (S1) which originates from a steamcracking process. The hydrocarbon mixture (HM1) obtained from this stream (S1) in an apparatus for aromatics removal has a reduced aromatics content compared to stream (S1), and (HM1) may optionally also be (virtually) free of aromatics. Depending on the type and amount of the aromatics remaining in the hydrocarbon mixture (HM1), especially in the case that benzene is present, the isomerization may additionally be preceded by performance of a hydrogenation of (HM1). In addition, depending on the presence of other components of (HM1), further purification steps may optionally be performed prior to or after the isomerization or hydrogenation.Type: GrantFiled: October 15, 2013Date of Patent: September 25, 2018Assignee: BASF SEInventors: Steffen Tschirschwitz, Kathrin Wissel-Stoll, Jochen Bürkle, Albena Kostova, Markus Schmitt, Veronika Wloka, Stephan Deuerlein, Marco Bosch, Steffen Oehlenschläger, Michael Schreiber, Gauthier Luc Maurice Averlant, Joni Joni, Roman Prochazka, Martin Bock, Alois Kindler, Daniela Malkowsky, Katharina Spuhl, Stefan Bitterlich, Daniel Pfeiffer

Publication number: 20140257007Abstract: The present invention relates to a chemical reaction process, preferably an isomerization process, of at least one hydrocarbon in the presence of an ionic liquid and a hydrogen halide (HX). The chemical reaction is carried out in an apparatus (V1) in which a gas phase is in direct contact with a liquid reaction mixture. The gas phase and the liquid reaction mixture each comprise the hydrogen halide and the liquid reaction mixture additionally comprises at least one hydrocarbon and the ionic liquid. Gaseous HX is introduced into the apparatus (V1) in such a way that the hydrogen halide partial pressure is kept constant in the gas phase. The ionic liquid used in the respective chemical reaction, in particular in an isomerization, can (inter alia) be regenerated by the process of the invention.Type: ApplicationFiled: March 6, 2014Publication date: September 11, 2014Applicant: BASF SEInventors: Stefan Bitterlich, Steffen Tschirschwitz, Jochen Bürkle, Michael Hübner

HYDROCARBON CONVERSION PROCESS IN THE PRESENCE OF AN ACIDIC IONIC LIQUID WITH UPSTREAM HYDROGENATION
Publication number: 20140128648Abstract: The present invention relates to a process for hydrocarbon conversion in the presence of an acidic ionic liquid. The hydrocarbon conversion is preferably an isomerization, especially an isomerization of methylcyclopentane (MOP) to cyclohexane. Prior to the hydrocarbon conversion, a hydrogenation is performed, preference being given to hydrogenating benzene to cyclohexane. The cyclohexane obtained in the hydrogenation and/or isomerization is preferably isolated from the process. In a preferred embodiment of the present invention, the hydrogenation is followed and the hydrocarbon conversion, especially the isomerization, is preceded by distillative removal of low boilers, especially C5-C6-alkanes such as cyclopentane or isohexanes, from the hydrocarbon mixture used for hydrocarbon conversion.Type: ApplicationFiled: October 15, 2013Publication date: May 8, 2014Applicant: BASF SEInventors: Roman Prochazka, Martin Bock, Steffen Tschirschwitz, Gauthier Luc Maurice Averlant, Joni Joni, Markus Schmitt, Katharina Spuhl, Jochen Bürkle, Alois Kindler, Daniela Malkowsky, Stefan Bitterlich, Michael Hübner -
Publication number: 20140114100Abstract: The present invention relates to a process for preparing cyclohexane from methylcyclopentane (MCP) and benzene. In the context of the present invention, MCP and benzene are constituents of a hydrocarbon mixture (HM1) additionally comprising dimethylpentanes (DMP), possibly cyclohexane and at least one compound (low boiler) selected from acyclic C5-C6-alkanes and cyclopentane. First of all, benzene is converted in a hydrogenation step to cyclohexane, while MCP is isomerized in the presence of a catalyst, preferably of an acidic ionic liquid, to cyclohexane. The hydrogenation is preceded by a prior removal of the dimethylpentanes (DMP), with initial removal of any cyclohexane present in the hydrocarbon mixture (HM1) together with DMP. This cyclohexane already present can be separated again from DMP in a downstream rectification step and recycled into the process for cyclohexane preparation.Type: ApplicationFiled: October 15, 2013Publication date: April 24, 2014Applicant: BASF SEInventors: Steffen Tschirschwitz, Nicole Holub, Jochen Burkle, Oliver Christian Gobin, Markus Schmitt, Martin Bock, Aisha Ahmad Naddaf, Katharina SpuhI, Stefan Bitterlich, Daniel Pfeiffer

Publication number: 20140114103Abstract: The present invention relates to a process for preparing cyclohexane from benzene and/or methylcyclopentane (MCP) by hydrogenation or isomerization. Prior to the cyclohexane preparation, the dimethylpentanes (DMP) are removed in a distillation apparatus (D1) from a hydrocarbon mixture (HM1) comprising not only benzene and/or MCP but also DMP. If cyclohexane is already present in the hydrocarbon mixture (HM1), this cyclohexane is first removed together with DMP from benzene and/or MCP. This cyclohexane already present can be separated again from DMP in a downstream distillation step and recycled into the process for cyclohexane preparation.Type: ApplicationFiled: October 15, 2013Publication date: April 24, 2014Applicant: BASF SEInventors: Markus Schmitt, Katharina Spuhl, Jochen Bürkle, Stefan Bitterlich, Steffen Tschirschwitz, Michael Hübner, Pawel Czajka
