摘要： There is provided a method for terminating a gas phase olefin polymerization reaction with a kill gas such as carbon monoxide or carbon dioxide. The method involves the use of coast-down flow of recycle gas during a failure of the power source of a compressor to carry kill gas into the reaction medium. The method is particularly adaptable to a fluid bed reactor system.

摘要： A catalyst composition for polymerizing alpha-olefins in a gas phase continuous process is prepared by combining a catalyst precursor with a catalyst activator in such proportions that the polymer product comprises about 9.times.10.sup.-7 to about 18.times.10.sup.-7 gram-moles of the activator per gram of the polymer produced. The use of the activator in these proportions lowers the partial pressure of the monomers used in the process without sacrificing quality of the product. The catalyst precursor is prepared by reacting a carrier having OH groups with a stoichiometric excess, with respect to the OH groups, of an organomagnesium composition, and subsequently reacting the product with a transition metal compound.

摘要： Methods for shutting down and restarting polymerization in a gas phase polymerization reactor are provided. The method can include introducing a polymerization neutralizer to the reactor in an amount sufficient to stop polymerization therein. The method can also include stopping recovery of a polymer product from the reactor and stopping introduction of a catalyst feed and a reactor feed to the reactor. The method can also include adjusting a pressure within the reactor from an operating pressure to an idling pressure. The method can also include adjusting a superficial velocity of a cycle fluid through the reactor from an operating superficial velocity to an idling superficial velocity. The method can also include maintaining the reactor in an idled state for a period of time.

摘要： A method for cleaning a distributor plate in a fluidized bed polymerization reactor system according to one embodiment includes, in a first mode, operating with about a normal, baseline value of superficial gas velocity in a fluidized bed polymerization reactor system having a reactor vessel, a recycle line, and a distributor plate in the reactor vessel near an inlet of the reactor vessel. In a second mode, the superficial gas velocity is increased above the baseline value of the first mode to a level sufficient to raise the temperature of the cycle gas at the inlet above an average temperature of the cycle gas at the inlet in the first mode, and to a level sufficient to dislodge foulant from holes in the distributor plate.
