    摘要： Methods for producing catalyst systems with increased productivity are disclosed. The methods may comprise providing a catalyst composition comprising a solvent and a single-site catalyst component, heating an inert gas to a temperature in a range of from about 100° C. to about 150° C., and spray drying the catalyst composition in the presence of the inert gas to form a spray-dried catalyst system. Additionally, the methods may comprise providing a catalyst composition comprising a solvent, an activator, a filler material, a metallocene catalyst, and a Group 15-containing catalyst; heating an inert gas to a temperature in a range of from about 100° C. to about 150° C.; and spray drying the catalyst composition in the presence of the inert gas to form a spray-dried catalyst system.

    摘要： The present disclosure provides a method for improving the activity of Ziegler-Natta (ZN) catalysts. The method includes forming a modified precursor composition of a ZN catalyst by providing a precursor composition of the ZN catalyst for treatment with an aluminum alkyl compound in a liquid organic solvent. The precursor composition of the ZN catalyst includes at least one titanium compound. The at least one titanium compound in the precursor composition is treated with the aluminum alkyl compound in the liquid organic solvent, where the aluminum alkyl compound converts the at least one titanium compound in the precursor composition into a modified state of the ZN catalyst. At least a portion of the aluminum alkyl compound not consumed in converting the at least one titanium compound in the precursor composition into the modified state of the ZN catalyst and reaction by-product compounds in the liquid organic solvent are removed to form the modified precursor composition of the ZN catalyst.
