Patent number: 11753258Abstract: A mixture of gas and solid particles are conveyed through a piping circuit connected between initial and terminal points. The gas is introduced at the initial point and the particles are introduced between the initial and terminal points. A diameter of the piping circuit increases downstream of where the particles are introduced, and a velocity of the gas is at least as great as a pick-up velocity of the particles at the point where the particles are introduced into the piping circuit. In addition to the above constraints, the piping circuit is sized so that total pressure losses due to flow in the piping circuit between the initial and terminal points are within a designated amount.Type: GrantFiled: September 23, 2021Date of Patent: September 12, 2023Assignee: Braskem America, Inc.Inventors: Shady Henry, Ronald Lutz

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

Publication number: 20060247394Abstract: Random copolymers may be prepared using a process that includes polymerizing a mixture of monomers including at least propylene and ethylene monomer, in the presence of a catalyst system including a metallocene catalyst having the general structure: racemic-X(2-R1-4-R2-Ind)2MCl2 wherein M is a Group 4, 5 or 6 transition metal, or a lanthanide or actinide series metal; X is a structural bridge imparting stereorigidity; R1 is hydrogen or an alkyl, aryl or a substitution moiety; R2 is hydrogen, or a C1-C4 alkyl; and Ind is an indenyl group. The copolymers are prepared under reaction conditions suitable to form a copolymer, wherein the copolymer has a higher level of ethylene incorporation than a corresponding polymer formed under otherwise identical reaction conditions except that a different bisindeny metallocene catalyst having a 4-indenyl substitution larger than 4 carbons is used. The copolymers may have a lower melt temperature than the corresponding polymers.Type: ApplicationFiled: April 29, 2005Publication date: November 2, 2006Applicant: Fina Technology, Inc.Inventors: William Gauthier, Jun Tian, Shady Henry, Nathan Williams
