Abstract
The invention relates to a process for production of propylene from a C4/C5 olefin cut (for example from steam cracking and/or catalytic cracking), this process comprising an optional selective hydrogenation, a selective oligomerization of the isobutenes and an oligocracking of the n-butenes. The invention makes it possible to obtain a high conversion rate with a good propylene yield and to maximize the production of good-quality gasoline.
