Publication number: 20020076543Abstract: In accordance with the present invention, compositions and methods are provided in which a layered low dielectric constant nanoporous material is produced that comprises a first layer juxtaposing a substrate; a second nanoporous layer juxtaposing the first layer; and an additional layer juxtaposing the second layer. The layered dielectrics of the present invention are formed using nanoporous materials by a) depositing a first layer on a substrate; b) depositing a second layer that is nanoporous and that juxtaposes the first layer; c) treating the second layered material to produce nanoporosity; and d) depositing at least one additional layer that partially juxtaposes the second layer. A layer of wires or other electronic components can also be situated between the substrate layer and the first layer.Type: ApplicationFiled: December 19, 2000Publication date: June 20, 2002Inventor: John G. Sikonia

Patent number: 4568447Abstract: A process for the removal of trace quantities of hydrocarbonaceous compounds from an aqueous stream which comprises the steps of: (a) contacting a solvent, which in the supercritical state is effective to dissolve the hydrocarbonaceous compounds from the aqueous stream, with the aqueous stream, for a time sufficient at supercritical solvent conditions to dissolve at least a portion of the hydrocarbonaceous compounds and to produce an aqueous stream having a reduced hydrocarbonaceous compound concentration; (b) separating the hydrocarbonaceous compounds from the solvent at subcritical conditions; and (c) recovering the hydrocarbonaceous compounds.Type: GrantFiled: July 29, 1985Date of Patent: February 4, 1986Assignee: UOP Inc.Inventors: Peter R.

Patent number: 4498973Abstract: A multiple-stage catalytic conversion system in which a hydrocarbonaceous charge stock and hydrogen flow serially through a plurality of catalytic reaction zones in each of which the catalyst particles are movable via gravity flow. Dissimilar catalyst particles are utilized in the reactor systems which share a common regenerating tower through which the catalyst particles are downwardly movable via gravity flow and in which the catalyst particles are regenerated in segregated fashion. Dissimilarity of the catalyst particles stems from a difference in activity, stability and selectivity characteristics. In turn, this difference may be attributed either to physical, or chemical distinctions between the two composites, or both.Type: GrantFiled: June 17, 1983Date of Patent: February 12, 1985Assignee: UOP Inc.Inventors: John G. Sikonia, Richard W. Bennett

Patent number: 4167473Abstract: A multiple-stage catalytic conversion system in which a hydrocarbonaceous charge stock and hydrogen flow serially through a plurality of catalytic reaction zones in each of which the catalyst particles are downwardly movable via gravity-flow. Dissimilar catalyst particles are utilized in the reactor systems, each of which is integrated with separate regenerating towers through which the catalyst particles are also downwardly movable via gravity-flow. Dissimilarity of the catalysts stems from a difference in activity and stability characteristics. In turn, this difference may be attributed either to physical, or chemical changes between the two composites, or a combination of both.Type: GrantFiled: May 2, 1978Date of Patent: September 11, 1979Assignee: UOP Inc.Inventor: John G.
