A method of producing a reformate suitable for use in the production of gasoline, comprising the steps of: obtain-ing naphtha heart cut (C5-C10+) from the distillation of gas condensate; removing undesired impurities from said naphtha heart cut (CS-C10+) by a hydrotreating step to produce hydrotreated naphtha heart cut (CS-C10+); and subjecting said hydrotreated naphtha heart cut (CS-C10+) to a catalytic reforming step to produce said reformate, wherein the temperature of said catalytic re-forming step is selected to be in the range 485-510 °C; and/or an amount of hydrotreated naphtha heart cut (C5-C10+) is mixed with said reformate such that said reformate contains up to 45 % volume of hydrotreated naphtha heart cut (C5-C10+), so as to re-duce the %volume of aromatics in said reformate. In addition, the invention comprises a method of producing a gasoline using such a reformate and also a gasoline comprising such a reformate.

Cette invention concerne un procédé de production d'un reformat approprié pour être utilisé dans la production d'essence, comprenant les étapes consistant à : obtenir une fraction de cur de naphta (C5-C10+) à partir de la distillation de gaz à condensat; éliminer les impuretés indésirables de ladite fraction de cur de naphta (CS-C10+) par une étape d'hydrotraitement pour produire une fraction de cur de naphta (CS-C10+) hydrotraitée; et soumettre ladite fraction de cur de naphta (CS-C10+) hydrotraitée à une étape de reformage catalytique pour produire ledit reformat, la température de ladite étape de reformage catalytique étant choisie dans la plage de 485 à 510 °C; et/ou une quantité de fraction de cur de naphta (C5-C10+) hydrotraitée est mélangée avec ledit reformat de telle sorte que ledit reformat contienne jusqu'à 45 % en volume de fraction de cur de naphta (C5-C10+) hydrotraitée, de manière à réduire le taux volumique de composants aromatiques dans ledit reformat. L'invention concerne par ailleurs un procédé de production d'essence utilisant ce reformat et également une essence comprenant un tel reformat.
