  • Process for the reduction of sulphur content in FCC heavy gasoline
    Patent number: 6103105
    Abstract: A process for the reduction of sulphur content in a FCC gasoline includes fractionation of the FCC gasoline into three fractions: a light fraction comprising 50-80% of the FCC gasoline, an intermediate boiling fraction comprising 10-30% of the FCC gasoline, and a heavy fraction comprising 5-20% of the FCC gasoline. The heaviest fraction is hydrotreated in the first bed of a hydrotreater at conditions that result in essentially total removal of the sulphur. The effluent from the first bed is quenched with the intermediate fraction. The combined oil stream is hydrotreated in a second and final bed in the hydrotreater at conditions that ensure the required overall sulphur reduction.
