ABSTRACT:
The invention concerns a fluidized bed cracking process of a hydrocarbon charge, carried out in an extended, appreciably tubular and vertical reaction zone (1), the catalyst being introduced at the lower end of this extended zone by a piper (2), and the charge being introduced by at least one pipe (3) opening into the reaction zone at a level higher than the level at which the catalyst is admitted.
The invention wherein, for example, part of the gasoline or part (3a) to an intermediate point between the catalyst and charge entry points, and wherein a specially adapted catalyst is used for this operating procedure. The invention also concerns the catalyst used in this way, a zeolite-based catalyst of the erionite family.
