    摘要: An object of the present invention is to provide a honeycomb structural body with a long service life, which can reduce a pressure loss to a low level upon collecting particulates and maintain the pressure loss at the low level for a long time even after regenerating processes. The honeycomb structural body includes a columnar porous ceramic block in which a large number of through holes are placed in parallel with one another in the length direction with a wall portion interposed therebetween. Herein, the large number of through holes are constituted by a group of large-capacity through holes, each of which is sealed at one end of the honeycomb structural body so that the total sum of the areas on a cross section perpendicular to the length direction is made relatively great, and a group of small-capacity through holes, each of which is sealed at the other end of the honeycomb structural body so that the total sum of the areas on the cross section is made relatively small, and a surface roughness Ry of the wall face of the through hole is set in a range from 10 to 100 μm.

    摘要: A honeycomb structure includes large-volume cells and small-volume cells with a cell wall therebetween; a plug sealing at either one of end portions of the cells; and a catalyst supported on the cell wall. The large-volume cell has a larger cross-sectional area perpendicular to its longitudinal direction than that of the small-volume cell. The large-volume cell is sealed at one end portion of the honeycomb structure, while the small-volume cell is sealed at the other end portion of the honeycomb structure. The catalyst is supported only on the cell walls forming the large-volume cells, or on both of the cell walls forming said large-volume cells and the cell walls forming said small-volume cells. An amount of the catalyst supported on the cell walls forming the large-volume cells is larger per unit volume than that on the cell walls forming the small-volume cells.

    摘要: A honeycomb structure includes a plurality of pillar-shaped honeycomb fired bodies bound with one another by interposing a adhesive layer. Each of the honeycomb fired bodies has a large number of cells longitudinally placed in parallel with one another with a cell wall therebetween. An adhesive strength A between central portion honeycomb fired bodies out of the honeycomb fired bodies measured by a three-point bending strength test is at least about 0.02 and at most about 0.2 MPa. The central portion honeycomb fired bodies are positioned at a central portion of a cross-section formed by cutting the honeycomb structure perpendicularly to the longitudinal direction. The adhesive strength A is lower than an adhesive strength B between peripheral portion honeycomb fired bodies out of the honeycomb fired bodies measured by the three-point bending strength test. The peripheral portion honeycomb fired bodies form a part of a periphery the honeycomb structure.
