摘要: A honeycomb structure includes honeycomb units. Each of the honeycomb units has a longitudinal direction and includes inorganic particles, an inorganic binder, and cell walls defining cells extending along the longitudinal direction from one end face to another end face. The honeycomb units are bonded together via an adhesive such that each longitudinal direction is substantially in parallel. An amount of ammonia desorbed per unit mass of the honeycomb units is about 5 to about 100 times greater than an amount of ammonia desorbed per unit mass of the adhesive. The amount of ammonia desorbed per unit mass of the honeycomb units and the amount of ammonia desorbed per unit mass of the adhesive are measured by an NH3-TPD method.

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.

摘要: A honeycomb structure includes at least one honeycomb unit having a longitudinal direction. The honeycomb unit includes SOx storage agent, inorganic particles, inorganic binder, and a partition wall extending along the longitudinal direction to define plural through holes. An expression Y≧−26X+40000 (0
