Abstract
A process for producing propylene from a steam cracking and/or catalytic cracking light olefinic cut, involves a moving bed catalytic cracking step with a catalyst regeneration loop. The process recycles a portion of the used catalyst to the inlet of the moving bed reactor. Nevertheless, the conversion is high, with a good yield and good propylene selectivity.
