Patent number: 5606087Abstract: An improved process for making aluminoxanes by the addition of water to a solvent solution of a hydrocarbylaluminum compound and/or an aluminoxane feeds the water through an orifice which is surrounded by a flow of solvent which carries the water into the solvent solution of hydrocarbylaluminum compound and/or aluminoxane.Type: GrantFiled: April 19, 1996Date of Patent: February 25, 1997Assignee: Albemarle CorporationInventors: John K. Roberg, Robert E. Farritor, Edward A. Burt

Patent number: 5599964Abstract: Aluminoxane is made by feeding water, hydrocarbylaluminum and organic solvent to a loop recycle reactor under conditions so as to react the water and hydrocarbylaluminum to form a hydrocarbylaluminoxane, removing a portion of the solvent and hydrocarbylaluminoxane from said reactor and recirculating the remaining portion of the reactor contents through a reaction zone where the water initially contacts the hydrocarbylaluminum. The feed rates of water, hydrocarbylaluminum and solvent to the reactor and the withdrawal rate of solvent and hydrocarbylaluminoxane from the reactor can be adjusted to produce a substantially steady state reaction.Type: GrantFiled: April 19, 1996Date of Patent: February 4, 1997Assignee: Albemarle CorporationInventors: John K. Roberg, Robert E. Farritor, Edward A. Burt

Patent number: 5322670Abstract: A product withdrawal tube for use in a fluidized bed reactor is disclosed. The tube features a plurality of elongated tubular segments which are fitted together to obtain flexible and sealing engagement between the segments whereby the tube is durable despite the vibrations and shocks experienced by it due to the operation of the fluidized bed reactor.Type: GrantFiled: October 20, 1992Date of Patent: June 21, 1994Assignee: Ethyl CorporationInventors: Jameel Ibrahim, Robert E. Farritor

Patent number: 5205998Abstract: An apparatus and process for maintaining the purity of solid/granular product and dispensing high purity granular product from a vessel. A noncontaminating surface is provided by a cup, cylinder, or other structure having a surface of silicon, silicon carbide, silicon nitride, sialon, or similar materials and preferably operates as an angle of repose valve in a pressurized system to prevent contamination by undue contact of the high purity product with conventional gastight valves such as ball valves, butterfly valves, pinch valves, etc.Type: GrantFiled: May 28, 1992Date of Patent: April 27, 1993Assignee: Ethyl CorporationInventors: James E. Boone, David W. Owens, Robert E. Farritor, Wesley D. Blank
