  • Patent number: 8318872
    Abstract: A method of performing a polymerization reaction in a gas phase polymerization reactor to produce a bimodal polymer while controlling activity of a bimodal polymerization catalyst composition in the reactor by controlling concentration of at least one induced condensing agent (‘ICA’) in the reactor is provided. In some embodiments, the ICA is isopentane (or another hydrocarbon compound) and the bimodal catalyst composition includes a Group 15 and metal containing catalyst compound (or other HMW catalyst for catalyzing polymerization of a high molecular weight fraction of the product), and a metallocene catalyst compound (or other LMW catalyst for catalyzing polymerization of a low molecular weight fraction of the product).

  • Patent number: 7989562
    Abstract: A system and method for olefin polymerization is provided. The method includes polymerizing one or more olefins within a reactor having one or more injection tubes in fluid communication therewith, at least one of the one or more injection tubes having two or more concentric flow paths; flowing a catalyst through a first flow concentric path of the injection tube into the reactor; flowing one or more monomers through a second concentric flow path of the injection tube into the reactor; measuring rate of heat removal within the reactor; and adjusting the one or more monomers flow through the injection tube in response to the rate of heat removal in the reactor.

  • Patent number: 7973112
    Abstract: A method for preparing a spray dried catalyst and a low viscosity, low foam spray dried catalyst system for olefin polymerization are provided. In one aspect, the method includes preparing a catalyst system including one or more components selected from metallocenes, non-metallocenes, and activators, adding mineral oil to the catalyst system to form a slurry, and adding one or more liquid alkanes having three or more carbon atoms to the slurry in an amount sufficient to reduce foaming and viscosity of the slurry. In one aspect, the catalyst system includes one or more catalysts selected from metallocenes, non-metallocenes, and a combination thereof, wherein the catalyst system is spray dried. The system further includes mineral oil to form a slurry including a catalyst system, and one or more liquid alkanes having three or more carbon atoms in an amount sufficient to reduce foaming and viscosity of the slurry.
