Production of the fuel base is free of benzene, having an octane number high.

摘要

The invention relates to a process for reducing the benzene content and isomerisation of paraffins, in which it is subjected to isomerization of the mixture of the charge, characterized by br / a composition by weight lying in the following intervals: & br / between 40 and 80% of paraffins br / between 0,5 and 7% of naphthenes br / between 6 and 45% of aromatics; br / and a maximum temperature of between 70 and 90degré c & br / and a section through c5 / c6 of the direct distillation, in the presence of an isomerization catalyst.
