Patent number: 8829124Abstract: The invention relates to a process for preparing polyolefin in a loop reactor. The polymer is prepared by polymerizing olefin monomers in the presence of a catalyst to produce a polyolefin slurry while pumping said slurry through said loop reactor by means of a pump. The present process is characterized in that the catalyst is fed in the loop reactor at a distance to the pump. The invention allows production of the polymer with advantageous properties while leading to fewer blockages of the reactor.Type: GrantFiled: December 2, 2013Date of Patent: September 9, 2014Assignee: Total Research & Technology FeluyInventors: Eric Damme, Louis Fouarge, Jerome Bette, Alvaro Fernandez, Aurelien Vantomme, Renaud Oreins, Daniel Siraux
