摘要： Disclosed is a catalyst pre-contact method for the continuous polymerization of an olefin, wherein a primary catalyst, a co-catalyst and, optionally, an external electron donor are mixed and then undergo a pre-contact reaction, with the pre-contact reaction temperature being −30° C. to 35° C. and adjustable, and the pre-contact reaction time being 0.5 min to 10 min and adjustable, and the pre-contacted catalyst is brought into a catalyst prepolymerization system and then into a catalyst polymerization system, or is directly brought into the catalyst polymerization system. Further disclosed is a catalyst pre-contact device for the continuous polymerization of an olefin, which can adjust the pre-contact time and pre-contact temperature of the catalyst so that the performance of the catalyst achieves a better level according to the process.

摘要： A magnesium-based solid, by means of determination based on a nitrogen adsorption method, has a multimodal pore distribution and a specific surface area of not less than 50 m2/g, and the pore size distribution of the solid is in a range of 1 nm to 300 nm. There is at least one peak within a pore size range of less than 10 nm, and there is at least another peak within a pore size range of not less than 10 nm. A catalyst is formed using the solid catalyst component is used for propylene polymerization.
