    摘要: The invention relates to the technical field of heterogeneous catalytic olefin polymerization, and discloses a polyolefin catalyst, its preparation and its us. A method for preparing the polyolefin catalyst comprises: (i) providing a thermally activated mesoporous material, with the thermal activation treatment being performed at a temperature of 300 to 900 °C for a period of time of 3 to 48 hours; (ii) under an inert atmosphere, (iia) conducting impregnation treatment of the thermally activated mesoporous material with a solution containing a magnesium component and then with a solution containing a titanium component, (iib) conducting impregnation treatment of the thermally activated mesoporous material with a solution containing a titanium component and then with a solution containing a magnesium component, or (iic) conducting co-impregnation treatment of the thermally activated mesoporous material with a solution containing both a titanium component and a magnesium component, to obtain a slurry to be sprayed; and (iii) spray drying the slurry to be sprayed from step (ii), to obtain a solid polyolefin catalyst component. When used in olefin polymerization, the polyolefin catalysts prepared by using the method provided by the invention have high catalytic activities, and polyolefin products having a narrow molecular weight distribution and an excellent melt index can be obtained.

    摘要: A magnesium halide solution is disclosed. The magnesium halide solution comprises a magnesium halide, an oxygen-containing organic titanium compound, a hydroxyl-containing compound, and an organic solvent. The magnesium halide solution further comprises an organic heterocyclic compound. The organic solvent is a hydrocarbon and/or a halogenated hydrocarbon. The organic heterocyclic compound is at least one selected from a group consisting of a sulphur-containing organic heterocyclic compound, a nitrogen-containing organic heterocyclic compound, and an organic epoxy compound. The magnesium halide solution has a good stability, and can be used for preparing a catalyst for olefin polymerization and copolymerization reactions. The raw material of the magnesium halide solution is cheap and easy to be obtained. The preparing method is easy to be performed and is environment-friendly.
