    Abstract: A catalyst carrier including a ceramic block having two open faces, an outer peripheral surface, and multiple cells divided by a cell wall and extending between the open faces. The ceramic block has multiple honeycomb units combined by interposing an adhesive layer, where the honeycomb units include an outer-peripheral-side honeycomb unit and a center-side honeycomb unit combined to form the outer peripheral part and the center part, respectively, of the block. The outer-peripheral-side honeycomb unit has an outer peripheral cell wall forming the outer peripheral surface of the outer-peripheral-side honeycomb unit. The outer peripheral cell wall includes an outermost peripheral cell wall forming part of the outer peripheral surface of the block. A cell of the outer-peripheral-side honeycomb unit in contact with the outermost peripheral cell wall thereof has a corner part having a curved surface, where the corner part is on the side contacting the outermost peripheral cell wall.

    Abstract: A honeycomb filter includes a honeycomb fired body having cells longitudinally disposed either end of each cell being sealed. The honeycomb filter includes an outlet-side catalyst supporting area, an inlet-side catalyst supporting area, and a catalyst unsupporting area formed between the catalyst supporting areas. A thermal conductivity of the catalyst unsupporting area is larger than those of the catalyst supporting areas. Y (%), Z (%), and X (%) satisfy the following inequalities, about 1≦Y≦about 19, (880−70Y)/9≦Z≦(825−15Y)/9 (about 1≦Y≦about 10), (330−15Y)/9≦Z≦(1375−70Y)/9 (about 10≦Y≦about 19), and X=100−Y−Z in which Y, Z, X indicate a ratio of a length of the outlet-side catalyst supporting area, the inlet-side catalyst supporting area, the catalyst unsupporting area, respectively, to an entire length of the honeycomb filter.

    Abstract: A catalyst supporting honeycomb includes a pillar-shaped honeycomb structure and catalyst particles supported on the honeycomb structure. The honeycomb structure includes cell walls extending in a longitudinal direction of the honeycomb structure to define a plurality of cells extending in the longitudinal direction. The plurality of cells include large-volume cells having first opening ends and second closing ends opposite to the first opening ends along the longitudinal direction, and small-volume cells having first closed ends and second opening ends opposite to the first closed ends along the longitudinal direction. Total cross sectional areas of the large-volume cells on a plane perpendicular to the longitudinal direction are larger than total cross sectional areas of the small-volume cells on the plane. The catalyst particles include an oxide catalyst having an average particle diameter of at least about 0.05 μm and at most about 1.00 μm.
