Title (EN) METHODS OF ACTIVATING CHROMIUM CATALYSTS
(FR) MÉTHODES D'ACTIVATION DES CATALYSEURS AU CHROME
Abstract: front page image
(EN)New methods for activating chromium catalysts for polymerization processes decrease the amount of time required for activation and increase catalyst activity. Rapid heating to a first temperature is followed by a first hold period before heating to a higher second temperature and maintaining the second temperature for a second hold period. In one aspect, the overall activation process takes less than 10 hours.
(FR)Nouvelles méthodes pour activer les catalyseurs au chrome afin que les processus de polymérisation abaissent le temps requis pour l'activation et augmentent l'activité de catalyse. Un chauffage rapide à une première température est suivi d'une première période d'attente avant un chauffage à une température plus élevée et le maintien de la deuxième température pendant une deuxième période d'attente. Pour un aspect, le processus d'activation global prend moins de 10 heures.
