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

Patent number: 9394212Abstract: In a process for the cooligomerization of olefins, an olefin starting material comprising olefins having n carbon atoms and olefins having 2n carbon atoms is reacted over an olefin oligomerization catalyst to give a reaction product. The process is carried out under such conditions that the conversion of olefins having 2n carbon atoms is less than 10%. Both the cooligomer having 3n carbon atoms and the olefin having 2n carbon atoms which has been separated off from the reaction product have a high hydroformylatability.Type: GrantFiled: June 14, 2011Date of Patent: July 19, 2016Assignee: BASF SEInventors: Wolfgang Rohde, Qiang Miao, Stefan Bitterlich, Gauthier Luc Maurice Averlant, Hans-Guenter Wagner, Beatrice Röβler-Feigel

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 -
