Abstract (en)
[origin: EP1972678A1] Treating charge of pyrolysis gasoline comprises: at least selective hydrogenation of charge called HD1; fractionating of hydrogenation effluent in more distillation columns to produce light cut C5, C6 intermediate cut or C6-C7 or C6-C8, and heavy cut C7+ or C8+ or C9+; hydrodesulfurization and deep hydrogenation of intermediate cut called HD2; at least alkylation of heavy cut C7+, C8+ and C9+ comprising treatment on acid catalyst; and distillation of alkylation effluent to produce light fraction of low sulfur content and heavy fraction C11+ or C12+ rich in sulfur content. Treating a charge of pyrolysis gasoline comprises: at least selective hydrogenation of the charge called HD1; fractionating of hydrogenation effluent in more distillation columns to produce at least a light cut C5, C6 intermediate cut or C6-C7 or C6-C8 intended to produce of aromatics, and a heavy cut C7+ or C8+ or C9+ intended to produce gasoline; hydrodesulfurization and deep hydrogenation of the intermediate cut called HD2; at least alkylation of heavy cut C7+, C8+ and C9+ comprising a treatment on acid catalyst which causes a heaviness of sulfur compounds; and at least distillation of the alkylation effluent to produce a light fraction of low sulfur content directly used as gasoline base, and a heavy fraction C11+ or C12+ rich in sulfur content used as a medium distillate or fuel.
