20140114103 | PROCESS FOR PREPARING CYCLOHEXANE COMPRISING A PRIOR REMOVAL OF DIMETHYLPENTANES - 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. | 04-24-2014 |
20140128648 | HYDROCARBON CONVERSION PROCESS IN THE PRESENCE OF AN ACIDIC IONIC LIQUID WITH UPSTREAM HYDROGENATION - 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.
