CONTINUOUS PREPARATION OF CALCINED CHEMICALLY-TREATED SOLID OXIDES

摘要

The present invention discloses a continuous calcination vessel which can be used to prepare calcined chemically-treated solid oxides from solid oxides and chemically-treated solid oxides. A process for the continuous preparation of calcined chemically-treated solid oxides is also provided. Calcined chemically- treated solid oxides disclosed herein can be used in catalyst compositions for the polymerization of olefins.
