Patent number: 7005485Abstract: A process is provided that produces polyolefins. The process comprises mixing a first stream, which comprises at least one catalyst deactivating agent, with a second stream, which comprises at least one polyolefin, at least one catalyst, at least one diluent, and at least one monomer, to produce a third stream, which comprises at least one polyolefin, at least one deactivated catalyst, at least one diluent, and at least one monomer. By utilizing the deactivating agent, polymerization can be slowed, or substantially stopped, when downstream equipment is being repaired or process control problems are being corrected. Later, polymerization can be restarted without the use of scavengers to remove poisons from the slurry polymerization reactor, and polyolefin production can be resumed.Type: GrantFiled: November 18, 2003Date of Patent: February 28, 2006Assignee: Chevron Phillips Chemical Company LPInventors: David H. Burns, Donald W. Verser, John D Hottovy, Michael C. Carter, Robert W. Bohmer

Patent number: 5348718Abstract: A method and apparatus are provided for producing a product comprising a carbide compound, such as for example silicon carbide. A reactor is provided which has a chamber defined therein which is divided into a combustion zone and a reaction zone. A combustible mixture is injected into the combustion zone in a direction generally toward the reaction zone, and is accordingly combusted in the combustion zone. At least one reactant (i.e. silane) is injected at the boundary between the zones into the reactor chamber in a direction generally parallel to the longitudinal axis of the chamber so as to react to form raw product comprising the carbide compound.Type: GrantFiled: April 4, 1990Date of Patent: September 20, 1994Assignee: Phillips Petroleum CompanyInventors: Michael C. Carter, Bruce W. Gerhold

Patent number: 5302366Abstract: A ceramic product comprising both carbon and nitrogen and a method for its production are provided. The product is formed in a reactor having a chamber defined therein which is divided into a combustion zone and a reaction zone. A combustible mixture is injected into the combustion zone in a direction generally toward the reaction zone, and is accordingly combusted in the combustion zone to produce hot combustion products. At least one reactant containing carbon, nitrogen and an additional component (i.e. silicon) is injected at the boundary between the zones into the reactor chamber so as to flow with the hot combustion products into the reaction zone and react to form the ceramic product.Type: GrantFiled: March 28, 1991Date of Patent: April 12, 1994Assignee: Phillips Petroleum CompanyInventors: George F. Schuette, Michael C. Carter, Bruce W. Gerhold

Patent number: 5248483Abstract: An apparatus and methods are provided for producing ceramic products in a reactor so as to minimize deposits therein. The reactor has a chamber defined therein which is divided into a combustion zone, into which a combustible mixture is injected, and a reaction zone in which the ceramic product is produced from at least one reactant injected into the chamber at the boundary between the zones. At least a portion of the wall defining the reaction zone is surrounded by at least one passageway through which coolant fluid is passed during ceramic production. Either carbide product or nitride product can be produced in the reaction zone according to the invention.Type: GrantFiled: March 28, 1991Date of Patent: September 28, 1993Assignee: Phillips Petroleum CompanyInventor: Michael C.

Patent number: 4348719Abstract: In a static inverter for providing a low-frequency output (e.g. 60 Hz) from a d.c. supply, the passage of low-frequency currents through the inverter transformer is avoided by producing a train of high-frequency pulses (e.g. 40 kHz) which represent, for example by their pulse widths, the successive instantaneous amplitudes of the required low-frequency voltage. These pulses cause a train of corresponding pulses to be produced at the secondary of the transformer, and this train is filtered to produce a unidirectional voltage having the desired instantaneous amplitudes. This voltage is fed to a transistor switching bridge which changes the unidirectional voltage into an alternating voltage having the required low frequency. A circuit is preferably provided to allow regeneration of power from the load back into the d.c. supply.Type: GrantFiled: October 19, 1979Date of Patent: September 7, 1982Assignee: ERA Patents LimitedInventors: Graham P. Hicks, Michael C. Carter
