Patent number: 9567416Abstract: The present invention relates to an apparatus and process for polymerizing olefins. One embodiment comprises polymerizing at least one monomer in a first loop reactor in the presence of a catalyst to produce a first polyolefin fraction. A portion of the first polyolefin fraction is transferred to a second loop reactor, connected in series with the first loop reactor. The process further comprises polymerizing in the second loop reactor at least one monomer in the presence of a catalyst to produce a second polyolefin fraction in addition to the first polyolefin fraction. The combination of the first and second polyolefin fractions can produce a polymer resin fluff having bimodal molecular weight distribution.Type: GrantFiled: December 22, 2015Date of Patent: February 14, 2017Assignee: TOTAL RESEARCH & TECHNOLOGY FELUYInventors: Louis Fouarge, Eric Damme, Olivier Miserque, Daniel Siraux, Philippe Bodart, Andre Lewalle, Marc Van der Auwera, Frans Van den Brande, Giacomo Conti, Hugo Vandaele, Mark Verleysen, Carl Van Camp, Etienne Laurent, Philippe Marechal, Marc Moers, Leopold D'Hooghe, Marjan Sillis, Kai Hortman, Pascal Folie, Renaud Oreins

Patent number: 8796400Abstract: A method for the copolymerization of ethylene and a C3+ olefin in a loop reactor and polymers formed therefrom are described herein. The method generally includes introducing an ethylene monomer, a C3+ olefin and a diluent carrier liquid into a loop reactor. A catalyst system can be supplied to said loop reactor. The diluent liquid, ethylene monomer, and C3+ olefin can be circulated through said loop reactor, while copolymerizing said ethylene and C3+ olefin in the presence of said catalyst system to produce a slurry. The slurry can be diverted into a settling leg, and sequentially discharged therefrom and withdrawn from said loop reactor. An ethylene monomer co-feed can be introduced into said loop reactor at spaced locations downstream of the ethylene and diluent. The ethylene co-feed can be introduced in an amount effective to reduce the variation in the ratio of ethylene and C3+ olefin.Type: GrantFiled: June 14, 2013Date of Patent: August 5, 2014Assignee: Total Research & Technology FeluyInventors: Louis Fouarge, Eric Damme, Olivier Miserque, Daniel Siraux, Philippe Bodart, Andre Lewalle, Marc Van der Auwera, Frans Van den Brande, Giacomo Conti, Hugo Vandaele, Mark Verleysen, Carl Van Camp, Etienne Laurent, Philippe Marechal, Marc Moers, Leopold D'Hooghe, Marjan Sillis, Kai Hortman, Pascal Folie, Renaud Oreins
