摘要:
A process for producing a honeycomb catalyst, comprising immersing an end face of honeycomb support in a slurry containing ceramic powder placed in a retention container. The slurry is forced into part of the cell structure of the honeycomb support through pressurization of the end face of honeycomb support toward the bottom of the retention container. The honeycomb support having the slurry forced into part of the cell structure is separated from the retention container. The slurry attached to the end face of honeycomb support is removed.

The present invention provides: a honeycomb structure produced by bonding with a bonding material containing 0.1 mass % or more of a heat-gelling organic binder having a thickening-initiating temperature of 75°C or lower, or a honeycomb structure produced by bonding with a thermosetting resin; and a process for producing a honeycomb structure, which comprises a bonding step of coating a bonding material containing 0.1 mass % or more of a heat-gelling organic binder having a thickening-initiating temperature of 75°C or lower, on the porous outer wall provided at the periphery of each cell structure, drying the coated bonding material at a temperature of 100°C or higher to form a bonding layer, and bonding the outer walls to each other via the bonding layer.
摘要:
There is disclosed a honeycomb structure 1 which is made of a ceramic material and in which a plurality of honeycomb segments 12 having cell structures 5 and porous outer walls 7 on outer peripheries of the cell structures 5 are integrated by bonding the outer walls 7 to one another with a bonding material, each of the cell structures being provided with a plurality of cells 3 constituting fluid channels divided by porous partition walls 2, wherein the bonding material contains a bio-soluble fiber. The honeycomb structure 1 of the present invention has a performance equivalent to that of a honeycomb structure in which a heretofore used ceramic fiber is contained.
摘要:
There is provided a honeycomb structure 10 comprising a honeycomb segment joined body 10 having a plurality of honeycomb segments 2 integrally joined with one another at a joint face of each of the honeycomb segments by means of a bonding material layer 9 and having a plurality of cells 5 functioning as fluid passages disposed in parallel with one another in a direction of central axis. Porosity in an outside portion of the bonding material layer 9 (portion from the interface of the joint face of honeycomb segments to the point corresponding to 20% thickness of the total bonding material layer) is smaller than that in the central portion located on the inner side of the outside portion.
