A two-stage hydrotreating process is disclosed wherein a hydrocarbon stream is first desulphurized followed by a dehydrogenation step, which process comprises in combination contacting the feed and hydrogen over a hydrotreating catalyst at hydrotreating conditions, heating the hydrotreated effluent and hydrogen-rich gas from the hydrotreating reactor and contacting said effluent and hydrogen gas over a hydrotreating catalyst in a post-treatment reactor at a temperature sufficient to increase the polyaromatic hydrocarbon content and lower the hydrogen content of said effluent.

Process for desulphurization of a hydrocarbon stream with a reduced consumption of hydrogen

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.
