Patent number: 8334230Abstract: A honeycomb structure includes at least one honeycomb unit which includes walls. The walls have a thickness of from about 0.10 mm to about 0.50 mm and extend along a longitudinal direction of the honeycomb structure to define through-holes. The honeycomb structure has a center area inside a boundary line passing through positions located at substantially a half of a length from a center of the honeycomb structure to a periphery of the honeycomb structure in a cross section perpendicular to the longitudinal direction. The honeycomb structure has a peripheral area outside the boundary line. A thickness of the walls located in the peripheral area is larger than a thickness of the walls located in the center area. A first opening ratio in the center area in the cross section is larger than a second opening ratio in the peripheral area in the cross section.Type: GrantFiled: July 22, 2009Date of Patent: December 18, 2012Assignee: Ibiden Co., Ltd.Inventors: Kazushige Ohno, Masafumi Kunieda, Takahiko Ido

Patent number: 8318625Abstract: A method of scavenging oil from an oil-water mixture includes providing a plurality of functionalized fly ash particles having functionalized surfaces including reactive groups or reactive materials having hydrophobic groups covalently bound to the reactive groups or reactive materials. The oil-water mixture is contacted with the plurality of functionalized fly ash particles. The plurality of functionalized fly ash particles absorb oil from the oil-water mixture to form oil-laden fly ash particles. The oil-laden fly ash particles can be fed into a combustion process to generate heat from oil absorbed thereon, or absorbed oil from the oil-laden fly ash particles can be separated using a desorption process, and the oil recovered after separating.Type: GrantFiled: July 11, 2011Date of Patent: November 27, 2012Assignee: University of Central Florida Research Foundation, Inc.Inventors: Sudipta Seal, David L.
