Title (EN) METHOD FOR FEEDING AN ANTISTATIC COMPOUND TO A POLYMERIZATION REACTOR
(FR) PROCÉDÉ POUR L'INTRODUCTION D'UN COMPOSÉ ANTISTATIQUE DANS UN RÉACTEUR DE POLYMÉRISATION
Abstract: front page image
(EN)A method for feeding an antistatic compound to a polymerization reactor comprising the steps of: a) dispersing, under mixing conditions, a catalyst powder and an antistatic compound in an oil, so as to form a suspension of catalyst powder and antistatic compound in said oil; b) successively adding, under mixing conditions, a molten thickening agent to said suspension from step a), while maintaining said suspension at a temperature such that said thickening agent solidifies on contact with said suspension; c) transferring the product obtained from b) to a polymerization reactor.
(FR)La présente invention concerne un procédé pour l'introduction d'un composé antistatique dans un réacteur de polymérisation comprenant les étapes suivantes: a) la dispersion, dans des conditions de mélange, d'une poudre catalytique et d'un composé antistatique dans une huile, de manière à former une suspension de poudre catalytique et de composé antistatique dans ladite huile; b) l'ajout successif, dans des conditions de mélange, d'un agent épaississant fondu à ladite suspension, tout en maintenant celle-ci à une température telle que ledit agent épaississant se solidifie en contact avec ladite suspension; et c) le transfert du produit obtenu lors de l'étape b) vers un réacteur de polymérisation.
