  • Publication number: 20150368377
    Abstract: Catalyst systems and methods for making and using the same are provided. The catalyst systems can include a plurality of silica particles and a metallocene catalyst and an activator supported on the plurality of silica particles. The polymerization catalysts have a particle size distribution in which about 10% of the particles have a size less than about 17 to about 23 micrometers, about 50% of the particles have a size less than about 40 to about 45 micrometers, and about 90% of the particles have a size less than about 72 to about 77 micrometers.

  • Publication number: 20150361192
    Abstract: 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.

  • Publication number: 20150344667
    Abstract: Catalyst systems and methods for making and using the same are provided. The catalyst system can include a catalyst support, wherein the catalyst support has an average particle size of about 2 microns to about 200 microns. Nanoparticles are adhered to the catalyst support, wherein the nanoparticles have an average particle size of about 2 to about 200 nanometers. A catalyst is supported on the catalyst support.
