Abstract:
A process for the reduction of sulphur content in a FCC gasoline comprising the steps of: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;hydrotreating of the heaviest fraction in the first bed of a hydrotreater at conditions that result in essentially total removal of the sulphur;quenching of the effluent from the first bed with the intermediate fraction to form a combined oil stream; andhydrotreating of the combined oil stream in a second bed in the hydrotreater at conditions that ensure the required overall sulphur reduction.
