Treatment of metathesis catalysts for olefins in a vibratory helicoidal conveyor |
摘要 |
A process for treatment of metathesis catalysts for olefins comprises sending the particles of catalysts through at least one vibratory helicoidal conveyor, subject the particles over at least a portion of their path and preferably over a large portion of their path to a temperature profile, and bringing the particles into contact with at least one fluid over at least a portion of their path. A vibratory helicoidal lifting device (12) makes it possible to regenerate metathesis catalysts for olefins: it comprises a combustion zone (14) and a calcination zone (15), as well as a preheating zone, a zone for stripping hydrocarbons and a zone for cooling the catalyst.
