Abstract: The present invention describes a process for converting a heavy feed which is flexible for the production of propylene, gasoline and middle distillate.The process uses a catalytic cracking unit and a unit for the oligomerization of C4 to C9 olefins. The process of the invention includes selective hydrogenation of the unrefined gasoline cut obtained from the catalytic cracking unit and separation between a light gasoline cut and a heavy gasoline cut, the light gasoline being directed to the oligomerization unit.

Abstract: A process for the treatment of a gasoline containing sulphur-containing compounds, olefins and diolefins, comprising the following steps: a) fractionating the gasoline in a manner such as to recover at least one intermediate gasoline cut, MCN, comprising hydrocarbons and wherein the temperature difference (ΔT) between the 5% and 95% by weight distillation points is less than 60° C.; b) desulphurizing the intermediate gasoline cut MCN alone and in the presence of a hydrodesulphurization catalyst and hydrogen in a manner such as to produce a partially desulphurized intermediate gasoline cut MCN; and c) fractionating, in a splitter, the at least partially desulphurized intermediate gasoline cut MCN which has not undergone catalytic treatment subsequent to step b), in a manner such as to recover an intermediate gasoline with low sulphur and mercaptans contents from the column head and a cut of hydrocarbons containing sulphur-containing compounds including mercaptans from the column bottom.

Abstract: A process for the concomitant production of at least two hydrocarbon cuts with low sulphur contents from a mixture of hydrocarbons having a total sulphur content in the range 30 to 10000 ppm by weight, by a) hydrodesulphurization in the presence of hydrogen and a hydrodesulphurization catalyst; b) separating hydrogen sulphide from the partially desulphurized effluent obtained from a); c) hydrodesulphurization of the partially desulphurized mixture obtained from b) in the presence of hydrogen and a hydrodesulphurization catalyst, the temperature of the second hydrodesulphurization being higher than that of the first hydrodesulphurization; d) fractionating the desulphurized mixture obtained in c) into at least two desulphurized hydrocarbon cuts.

Abstract: The present application concerns a process for the treatment of a gasoline containing sulphur-containing compounds and olefins, with the following steps: a) a step for hydrodesulphurization of said gasoline in order to produce an effluent which is depleted in sulphur by passing the gasoline mixed with hydrogen over at least one hydrodesulphurization catalyst; b) a step for separating the partially desulphurized gasoline from the hydrogen introduced in excess as well as the H2S formed during step a); c) a catalytic step for sweetening desulphurized gasoline obtained from step b), which converts residual mercaptans into thioethers via an addition reaction with the olefins.
