Patent

CA 2264438

In 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; and hydrotreating of the combined oil stream in a second and final bed in the hydrotreater at conditions that ensure the required overall sulphur reduction.
