Abstract

Procédé de production d'hydrocarbures aromatiques en C7 et/ou C8 de pureté élevée, par réformage de fractions de naphta en C7 et C8 à gamme d'ébullition des composés à même nombre d'atomes de carbone, ou de leurs combinaisons sous des conditions de réformage de sévérité suffisante pour convertir essentiellement tous les hydrocarbures non aromatiques présents dans la charge et ayant des points d'ébullition compris dans la gamme d'ébullition des hydrocarbures aromatiques de C7 à C8 , en hydrocarbures aromatiques en C7 et/ou C8 et, ensuite, par séparation du réformat en fractions d'hydrocarbures aromatiques en C7 et/ou C8 de pureté élevée, par distillation fractionnée. De préférence, on réforme la faction de naphta en C7 et/ou C8 à gamme d'ébullition des composés de même nombre d'atomes de carbone dans un système de réformage à plusieurs étages avec des conditions de sévérité croissante de façon à obtenir un rendement maximum en hydrocarbures aromatiques en C7 et C8 .
