    摘要： The invention concerns a process for producing propylene, especially from a light steam cracking and/or catalytic cracking cut, preferably comprising both butenes and pentenes, said process comprising a step for moving bed catalytic cracking with a catalyst regeneration loop. The catalyst comprises at least one zeolite with a zeolitic composition with a Si/Al ratio which is preferably less than 130.The invention can produce a high conversion with a good yield of propylene at a high space velocity, meaning that the volume of catalyst can be reduced.

    摘要： The invention relates to a process for production of propylene in particular from a C4 and/or C5 cut from steam cracking and/or catalytic cracking, preferably comprising both butenes and pentenes, said process comprising at least one oligomerization stage, followed by a stage of catalytic cracking of the oligomers formed.Preliminary oligomerization, in particular of a wide fraction of the charge, makes it possible to optimize the yields, the conversion, and the selectivity for propylene, relative to direct cracking. It also makes it possible for cracking to be carried out in a fixed, moving, or fluidized bed, optionally with co-production of oligomers for uses other than the production of propylene.
