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

摘要

Reduction in the benzene content in the gasoline pool, in which hydrogenation is carried out of the feedstock characterised by a weight composition included within the following ranges: - between 40 and 80 % of paraffins - between 0.5 and 7 % of naphthenes - between 6 and 45 % of aromatics and a maximum distillation temperature of between 70 and 90@C, then an isomerisation of the said feedstock is carried out, the process being characterised in that the said feedstock has been mixed with a C5-C6 direct distillation cut at at least one of the following times: - just before the hydrogenation, - just before the isomerisation and after the hydrogenation of the said feedstock.
