Abstract

La continuité dun catalyseur/réacteur contenant un ligand à base de kétimide dans une réaction en phase dispersée au chapitre de lactivation initiale et la désactivation subséquente peut être améliorée en traitant le support avec un sel métallique. Lactivateur et le catalyseur sont ensuite déposés sur le support traité. Le catalyseur obtenu présente une consommation inférieure déthylène durant linitiation et un taux plus faible de désactivation. De préférence, le catalyseur est utilisé avec un agent antistatique.
