Patent number: 8323767Abstract: A honeycomb structure includes at least one a honeycomb unit having a longitudinal direction. The at least one honeycomb unit includes a SOx occluding agent, inorganic particles, an inorganic binder, and partition walls extending along the longitudinal direction to define plural through-holes. A relationship 5X+30?Y?5X+45 (about 1.0?X?about 2.5) is satisfied, wherein a content of the SOx occluding agent in the partition walls is expressed by X (mol/L) and a porosity of the at least one honeycomb unit is expressed by Y (%).Type: GrantFiled: October 7, 2008Date of Patent: December 4, 2012Assignee: Ibiden Co., Ltd.Inventors: Takahiko Ido, Chizuru Kasai

Patent number: 8323766Abstract: A honeycomb structure includes at least one honeycomb unit having a longitudinal direction. The honeycomb unit includes SOx storage agent, inorganic particles, inorganic binder, and a partition wall extending along the longitudinal direction to define plural through holes. An expression Y??26X+40000 (0<X?approximately 500) is satisfied, wherein “X” represents an amount [g] of SOx stored in the honeycomb structure, and “Y” represents a specific surface area [m2/L] of the honeycomb structure when “X” [g] of SOx is stored in the honeycomb structure.Type: GrantFiled: September 26, 2008Date of Patent: December 4, 2012Assignee: Ibiden Co., Ltd.Inventors: Takahiko Ido, Chizuru Kasai

Patent number: 7901755Abstract: A honeycomb structure includes a plurality of pillar-shaped honeycomb fired bodies, each having a large number of cells longitudinally placed in parallel with one another with a cell wall therebetween. The honeycomb fired bodies are combined with one another by interposing adhesive layers containing at least ceramic particles. In the ceramic particles contained in the adhesive layers, the number of those particles having a particle diameter larger than an average pore diameter of the honeycomb fired body is set to 30% or less of the total number of the ceramic particles.Type: GrantFiled: October 26, 2007Date of Patent: March 8, 2011Assignee: Ibiden Co., Ltd.Inventors: Takahiko Ido, Chizuru Kasai

Publication number: 20080119355Abstract: A method for manufacturing a honeycomb structure includes mixing inorganic particles, at least one of inorganic fibers and inorganic whiskers, and an inorganic binder solution to prepare a raw material composition. The method further includes manufacturing a pillar-shaped honeycomb molded body by extrusion-molding the raw material composition, and firing the molded body to manufacture a honeycomb fired body. The molded body has a large number of cells disposed in substantially parallel with one another in a longitudinal direction with a cell wall therebetween. A blending amount of the inorganic binder solution is about 30 to about 60% by weight to the total amount of the inorganic particles, at least one of the inorganic fibers and the inorganic whiskers, and the inorganic binder solution. A concentration of the inorganic binder solution is about 35 to about 50% by weight.Type: ApplicationFiled: November 13, 2007Publication date: May 22, 2008Applicant: IBIDEN CO., LTD.Inventors: Kazushige Ohno, Takahiko Ido, Chizuru Kasai
