Abstract

L'invention concerne la réduction de la proportion des fines dans un catalyseur particulaire. Elle se rapporte à un procédé qui comprend la mise en suspension d'un catalyseur dans un liquide inerte, la sédimentation partielle de la suspension afin que la partie supérieure contienne essentiellement des fines et la partie inférieure les grosses particules, et la séparation des parties supérieure et inférieure. Application au classement des catalyseurs de polymérisation des oléfines.
