HYDROCARBON CONVERSION METHOD IN THE PRESENCE OF AN ACIDIC IONIC LIQUID WITH PRIOR HYDROGENATION

摘要

The invention relates to a method for hydrocarbon conversion in the presence of an acidic ionic liquid. The hydrocarbon conversion is preferably an isomerization, in particular an isomerization of methylcyclopentane (MCP) to form cyclohexane. Before the hydrocarbon conversion, a hydrogenation is performed. Preferably, benzene is hydrogenated to form cyclohexane. The cyclohexane arising in the hydrogenation and/or isomerization is preferably isolated from the method. In a preferred embodiment of the invention, low boilers, in particular C5-C6 alkanes such as cyclopentane or isohexanes, are removed by distillation from the hydrocarbon mixture used for the hydrocarbon conversion after the hydrogenation and before the hydrocarbon conversion.
