摘要：NOVELTY - A polyethylene supported vanadium-chromium dual active site catalyst comprises an inorganic carrier, and dual active site component containing chromium oxide and vanadium oxide. USE - Polyethylene supported vanadium-chromium dual active site catalyst is used for preparing ethylene homopolymer and copolymer of ethylene and alpha -olefin (all claimed). ADVANTAGE - The polyethylene supported vanadium-chromium dual active site catalyst is efficiently prepared with high activity and sensitivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of catalyst, which involves impregnating inorganic carrier with vanadium solution, drying at 300-900 degrees C, roasting and activating at high temperature of 300-900 degrees C.
