Abstract (en)

[origin: EP1138749A1] Dividing starting petroleum fraction into heavy, light and intermediate fractions and subjecting previously desulfurized intermediate fraction to catalytic reforming. The process comprises: a1) at least one selective hydrogenation of diolefins and acetylenes present in starting material; b) at least one separation of obtained effluent into 3 fractions: light fraction practically free from S and containing lightest olefins, heavy fraction containing majority of initially present S, and at least one intermediate fraction with relatively low content of olefins and aromatic compounds; c1) at least one catalytic treatment of heavy fraction to decompose/hydrogenate at least partially unsaturated S compounds; and d) at least one desulfurization/denitration of at least one intermediate fraction, followed by catalytic reforming. Starting material is preferably a benzine fraction from catalytic cracking.
