Method for the direct conversion of a charge containing olefins comprising a minimum of four or five carbon atoms, for producing propylene |
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.
