Abstract (en)
[origin: EP1640436A1] Preparation of an isomerate (I) and coproduction of a naphthenic fraction (F) (comprising mainly methylcyclohexane and optionally toluene) from a fraction (comprising hydrocarbons containing paraffins, naphthenes and aromatics), comprises: using a distillation column, at least an isomerization unit and separation unit for normal paraffin and cyclic molecules, where (I) contains less than 1 (preferably 0.5) wt.% of aromatics. Preparation of an isomerate (I) (having research octane number of 80) and coproduction of a naphthenic fraction (F) (comprising mainly methylcyclohexane and optionally toluene) from a fraction (comprising hydrocarbons (with 7 carbon atoms) containing paraffins, naphthenes and aromatics), comprises: using a distillation column, at least an isomerization unit and separation unit for normal paraffin and cyclic molecules (preferably methylcyclohexane), where (I) contains less than 1 (preferably 0.5) wt.% of aromatics.
