    摘要： An object of the present invention is to provide a honeycomb structural body for use in a filter, which can be provided with a large amount of catalyst, can suppress an increase in pressure loss upon collecting particulates, can have a high particulate collecting capability and can efficiently carry out a regenerating process and a toxic gas purifying process. The honeycomb structural body of the present invention is a pillar-shaped honeycomb structural body that is mainly composed of inorganic fibers and has a structure in that a large number of through holes are placed in parallel with one another in the length direction with a partition wall interposed therebetween. Herein, the inorganic fibers, which form the honeycomb structural body, are arranged in such a manner that more fibers are aligned along a face perpendicular to the forming direction of the through holes rather than aligned along a face in parallel with the forming direction of the through holes.

    摘要： An object of the present invention is to provide a honeycomb structural body which makes it possible to prevent a thermal stress from concentrating on plugs for sealing a group of inlet-side through holes and the vicinity thereof during a regenerating process, and consequently to prevent occurrence of cracks. The honeycomb structural body of the present invention is a pillar-shaped honeycomb structural body mainly made of porous ceramics, in which a plurality of through holes are placed in parallel with one another in the length direction with a partition wall interposed therebetween. Herein, the through holes are constituted by a group of inlet-side through holes, whose ends are sealed by plugs at the outlet side such that the total sum of areas on cross sections perpendicular to the length direction is made relatively greater, and a group of outlet-side through holes, whose ends are sealed by plugs at the inlet side such that the total sum of areas on the cross sections thereof is made relatively smaller. Supposing that the aperture rate on the inlet side is X (%) and that the total sum of thermal capacities of the plugs which seal the group of inlet-side through holes at 500° C. per 11.8 cm2 of the end face on the outlet side containing the group of the outlet-side through holes is represented by Y(J/K), the relationship indicated by the following inequalities (1) and (2) is satisfied. 0.0157X−0.0678

    摘要： 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.
