Title:
少なくとも3留分への分別により生じた重質フラクションおよび中間フラクションの脱硫を含むガソリンの脱硫方法
Document Type and Number:
Japanese Patent JP4798324
Kind Code:
B2
Abstract:
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.
