HIGH CONDENSING MODE POLYOLEFIN PRODUCTION UNDER TURBULENT CONDITIONS IN A FLUIDIZED BED
A fluidized bed olefin polymerization process is operated in the turbulent regime while utilizing greater than (17.5) percent liquid in the recycle fluid to remove the heat of reaction. The ratio of fluidized bed density to settled bed density may, contrary to prior art predelictions, be maintained...

| description | A fluidized bed olefin polymerization process is operated in the turbulent regime while utilizing greater than (17.5) percent liquid in the recycle fluid to remove the heat of reaction. The ratio of fluidized bed density to settled bed density may, contrary to prior art predelictions, be maintained at lower than (0.59).
Procédé de polymérisation d'oléfines dans un lit fluidisé fonctionnant en régime de turbulence, selon lequel plus de 17,5 pour cent de liquide est utilisé dans le fluide de recyclage pour dissiper la chaleur de réaction. Contrairement à la pratique préférée selon l'état antérieur de la technique, le rapport entre la densité du lit fluidisé et la densité du lit immobilisé peut être maintenu à une valeur inférieure à 0,59. |
