Lowering of the benzene content in gasolines.

摘要

Process for reducing the benzene content and isomerising paraffins, in which an isomerisation is performed of the mixture (a) 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 DEG C, and (b) of a C5-C6 direct distillation cut, in the presence of an isomerisation catalyst.
