Abstract

Un produit à teneur réduite en soufre est produit à partir d'une charge d'alimentation constituée d'un mélange d'hydrocarbures et qui contient des impuretés indésirables sous forme de composés de soufre organiques. Le procédé comporte, d'une part, la transformation d'au moins une partie des impuretés contenant du soufre en produits contenant du soufre dotés d'un point d'ébullition plus élevé, au moyen d'un traitement par un agent alkylant en présence d'un catalyseur acide et, d'autre part, l'extraction, par distillation fractionnée, d'au moins une partie de ces produits dotés d'un point d'ébullition plus élevé. Parmi les agents alkylants qui conviennent à ce type de réaction, on trouve des alcools et des oléfines. Dans une réalisation préférée, on utilise les produits de craquage catalytique qui contiennent des impuretés sous forme de composés aromatiques de soufre, comme charge d'alimentation du processus.
