Abstract

The present invention provides a honeycomb structure including a honeycomb structure portion having a partition wall partitioning a compartment; a compartment is provided with protrusions on both sides extending from a corner of the compartment; a protrusion disposed at a shorter distance from the one corner portion to the protrusion portion from a corner extending from a corner portion and located at a position closest to the corner portion as a first protrusion portion; a protrusion disposed at a longer distance from the one corner portion to the protrusion portion from a corner extending from a corner portion and located at a position closest to the corner portion as a second protrusion portion; the length of one side on which the second protrusion is provided is L, the distance from the corner portion to the bottom center position of the second protrusion is A, and the number of protrusions on the side on which the second protrusion is provided is N,the relationship of the formula(1): 1 / (N+1) < A / L is satisfied. The ratio of the total number of corners formed to satisfy the relationship of the formula (1) to the total number of corners of all the cells in the honeycomb structure portion is 2.5% or more.

Description

technical field

[0001] The present invention relates to a honeycomb structure. More specifically, it relates to a honeycomb structure that can be used particularly preferably as a catalyst carrier for supporting an exhaust gas purification catalyst. Background technique

[0002] In recent years, awareness of environmental issues has increased throughout society. Therefore, in the technical field of generating power by burning fuel, various technologies for removing harmful components such as nitrogen oxides from exhaust gas generated during fuel combustion are being developed. Furthermore, as various technologies for removing harmful components, for example, various technologies for removing harmful components such as nitrogen oxides from exhaust gas emitted from automobile engines are being developed. When removing harmful components in the exhaust gas in this way, a catalyst is usually used to chemically react the harmful components to change them into another relatively...
