Abstract
The present invention describes a process for the conversion of a heavy feed which can be used to improve the selectivity for middle distillate. The process employs a catalytic cracking unit followed by one or more units for the oligomerization of C2 to C9 olefins which can preferentially produce an additional cut termed the middle distillate. The light portion of the oligomerate produced which cannot be incorporated into the middle distillate cut is recycled to the FCC unit for cracking into light olefins which are returned to the oligomerization units as a supplement to the olefins of the feed in order to preferentially form heavy oligomerates which can be incorporated into the middle distillate cut.
