Patent number: 8436112Abstract: The invention is directed to a metallocene catalyst system comprising an inert silica support having pores with a peak pore volume of greater than about 0.115 mL/g at a pore diameter between about 250 Angstroms and about 350 Angstroms, and an alumoxane activator, with the metallocene being bound substantially throughout the support. The activator is grafted to the support in a solvent at a reflux temperature of toluene to obtain an aluminoxane on silica, and a metallocene component is added to make a MCS having a metallocene loading of about 2 wt %. This facilitates the production of metallocene catalyst systems having increased catalytic activity than previously recognized that is at least about 20 percent higher than the catalytic activity for a metallocene loading of about 1 wt % where the activator is grafted to the support at room temperature.Type: GrantFiled: January 14, 2008Date of Patent: May 7, 2013Assignee: Fina Technology, Inc.Inventors: Jun Tian, William Gauthier, David Rauscher, Shady Henry
