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.
