Abstract
The present invention describes a process for the production of gasoline and for the co-production of propylene employing a catalytic cracking unit having at least one principal reactor operating in riser mode or in downer mode, processing a conventional heavy feed, and in which the principal reactor further processes a feed primarily constituted by olefinic C4, C5 and C6 cuts introduced upstream or as a mixture with said heavy feed, said olefinic feed deriving from the inter-stage of the wet gas compressor, i.e. upstream of the separation section of the catalytic cracking unit.
