摘要： PROBLEM TO BE SOLVED: To provide foil and a honeycomb structure using the same for producing a catalyst carrier which is excellent in temperature rising characteristics after the start of an engine, i.e. excellent in exhaust gas purifying performance without uselessly thinning foil thickness and without providing slot machinning, a heating mechanism and a heat-insulating mechanism. SOLUTION: The foil consists of Al-containing heat resistant steel foil, and the inside thereof comprises an isolated gap. Using t as the thickness of the foil, the gap is located within t/7 from the surface of the foil to the sheet thickness of the foil. The size of the gap is 0.1 to 5 μm. The thickness of the foil is 10 to 70μm. The honeycomb structure is obtained by using the foil. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device capable of homogenizing radial direction distribution of exhaust gas temperature at a time of temperature rise of exhaust gas at a filter front surface and starting combustion of PM almost simultaneously in a filter radial direction in exhaust emission control devices having a filter 3 collecting particulate matter in exhaust gas and an oxidation catalyst carrier 2 arranged on an upstream side thereof. SOLUTION: In the exhaust emission control device, the oxidation catalyst carrier 2 consists of two kinds of base material from a radial direction center part to an outer circumference part. Base material positioned at the outer circumference part has higher heat capacity than base material positioned at the center part. Also, the oxidation catalyst carrier 2 includes many cells through which exhaust gas passes, and cell density of the base material positioned at a radial direction center part is higher than cell density of the base material positioned at the outer circumference part. Moreover, axial direction length of the oxidation catalyst carrier 2 changes from the radial direction center part to the outer circumference part, axial direction length at the center part is longer than axial direction length at the outer circumference part.

摘要： PROBLEM TO BE SOLVED: To provide a catalyst carrier capable of enhancing anti-oxidation property of a stainless steel foil and reducing thermal stress in the catalyst carrier for cleaning exhaust gas using a honeycomb body with Fe-Cr-Al-based stainless steel foils laminated. SOLUTION: The catalyst carrier for cleaning the exhaust gas is characterized in that the honeycomb body with Fe-Cr-Al-based stainless steel foils laminated is used and that Al contents contained in the stainless steel foil constituting the honeycomb body are different between an exhaust gas entrance side and an exhaust gas exit side. Regarding the Al content contained in the stainless steel foil, the content at the exhaust gas entrance side is higher than the content at the exhaust gas exit side. The Al content in terms of mass% contained in the stainless steel foil is 7 to 25% at an end of the exhaust gas entrance side and is 3% to less than the amount at the end of the entrance side at an end of the exhaust gas exit side.

摘要： PROBLEM TO BE SOLVED: To provide a catalyst converter preventing the thick coating part of a wash coat layer and having good catalytic capacity, and a method for manufacturing the same. SOLUTION: In the catalyst converter, the wash coat layer for supporting a noble metal catalyst is constituted of an aggregate of relatively large particles with a particle size of 10-200 μm. By this constitution, a contact area with gas becomes large as compared with a washing coat layer using only a usual slurry and a wash coat sump at a corner part can be markedly reduced while ensuring the wash coat thickness of a flat part. Therefore, the mass of the coated wash coat layer can be rather reduced as compared with the wash coat layer formed by the method using the usual slurry and the heat capacity of the catalyst becomes small and the warm-up property are also enhanced effectively.
