Abstract:

This invention relates to a method to introduce multiple catalysts into a gas or slurry phase reactor comprising: (a) introducing one or more olefins and a first catalyst and an activator into the reactor and allowing the olefins to polymerize, (b) obtaining a polyolefin, (c) introducing a second catalyst and an optional activator into the first catalyst/activator composition and thereafter introducing the combination into the reactor and allowing the olefins to polymerize. This invention further relates to a method to introduce multiple catalysts into a gas or slurry phase reactor comprising: (a) introducing one or more olefins, a first catalyst and an activator, and a second catalyst and an optional activator into the reactor, wherein the all the catalysts and activators are combined together prior to being introduced into the reactor.

Assignee:

Union Carbide Chemicals Plastics Technology Corporation - Danbury CT

International Classification:

C08F 234

US Classification:

526 70, 526 59, 526 61, 526 68, 526 72, 526351, 526352, 526348

Abstract:

A fluidized bed olefin polymerization process is operated in the turbulent regime while utilizing greater than 17. 5% liquid in the recycle fluid to remove the heat of reaction. The ratio of fluidized bed density to settled bed density may, contrary to prior art predelictions, be maintained at lower than 0. 59.

Assignee:

Union Carbide Chemicals Plastics Technology Corporation - Danbury CT

International Classification:

C08F 234

US Classification:

526 88, 526 86, 526 68

Abstract:

A process, carried out in the gas phase, comprising contacting one or more olefins with a catalyst system containing a carrier gas and a mixture of solids comprising a transition metal compound or complex and a liquid organic solvent, under polymerization conditions, in a fluidized bed reactor containing resin particles in a fluidized state with the provisos that (a) the mixture of solids and solvent contains at least about 95 percent by weight solids and (b) the mixture is sprayed with the carrier gas into a particle-lean zone, or the fluidized bed, of the reactor.

International Classification:

C08F 234

US Classification:

526 88, 526 65, 526 70

Abstract:

The liquid content of granular product removed from a fluidized bed polymerization reactor operating in the condensing mode is reduced or minimized by removing the product from a level in the fluidized bed which is about 0. 21 to about 0. 59 of its height while venting the product discharge tank to a point higher in the fluidized bed.

International Classification:

C08G 8500

US Classification:

526 68, 526901

Abstract:

The present invention relates to a method to polymerize monomer comprising contacting one or more monomer(s) with a catalyst system in a gas phase reactor having a recycle system, for removing a recycle gas and unreacted monomer(s) from the reactor and returning the recycle gas and fresh monomer(s) to the reactor, and a plenum, the method comprising the steps of: (a) cooling the recycle gas to form a cooled recycle gas; (b) optionally combining the cooled recycle gas with additional recycle gas; and (c) injecting the cooled recycle gas into the gas phase reactor through the plenum.
