摘要: A honeycomb structure includes at least one honeycomb unit which includes walls. The walls have a thickness of from about 0.10 mm to about 0.50 mm and extend along a longitudinal direction of the honeycomb structure to define through-holes. The honeycomb structure has a center area inside a boundary line passing through positions located at substantially a half of a length from a center of the honeycomb structure to a periphery of the honeycomb structure in a cross section perpendicular to the longitudinal direction. The honeycomb structure has a peripheral area outside the boundary line. A thickness of the walls located in the peripheral area is larger than a thickness of the walls located in the center area. A first opening ratio in the center area in the cross section is larger than a second opening ratio in the peripheral area in the cross section.

摘要: A honeycomb structure includes a center area, an outer peripheral area, and at least one honeycomb unit having a longitudinal direction. The center area has a smaller similarity shape in relation to a peripheral shape of the honeycomb structure in a cross section perpendicular to the longitudinal direction. The smaller similarity shape is defined by including a center of the honeycomb structure and substantially a half of a length from the center to the peripheral shape of the honeycomb structure. The outer peripheral area is located outside the smaller similarity shape. An aperture ratio of the honeycomb structure is from approximately 50% to approximately 65% in the cross section of the honeycomb structure. The aperture ratio includes a first aperture ratio in the outer peripheral area and a second aperture ratio in the center area. The first aperture ratio is larger than the second aperture ratio.

The honeycomb unit has an opening ratio (%) of about 57% or more. The opening ratio is equal to or less than y shown in a formula of y=0.55x+30 when a content x (mass %) of the zeolite included in the honeycomb unit is less than about 66 mass %. The opening ratio is equal to or less than y shown in a formula of y 32 −0.25x+82.8 when the content x (mass %) is about 66 mass % or more.

摘要: A honeycomb structure includes at least one honeycomb unit. The at least one honeycomb unit has a longitudinal direction and includes an inorganic binder, a cell wall, and xeolite. The cell wall extends from a first end face to a second end face of the at least one honeycomb unit along the longitudinal direction to define cells. The at least one honeycomb unit includes the zeolite in an amount exceeding approximately 250 g/L per apparent volume. The xeolite is present at a first concentration at a center part of a thickness of the cell wall and at a second concentration at a surface of the cell wall. The second concentration is larger than the first concentration.

摘要: A honeycomb structure includes at least one honeycomb unit having a longitudinal direction and including zeolite, an inorganic binder, and walls. The zeolite includes a first zeolite ion-exchanged with at least one of Cu, Mn, Ag, and V and a second zeolite ion-exchanged with at least one of Fe, Ti, and Co. Each wall has first and second surfaces which extend along the longitudinal direction and define a thickness of each wall. A ratio of the first zeolite by weight to a total weight of the first and second zeolites at a center of the thickness of each wall is larger than the ratio of the first zeolite at the first or second surface. A ratio of the second zeolite by weight to the total weight at the first or second surface is larger than the ratio of the second zeolite at the center of the thickness of each wall.
