Honeycomb structure and exhaust gas conversion apparatus

摘要

A honeycomb structure includes at least one pillar shaped honeycomb unit including zeolite and an inorganic binder, the honeycomb unit including a plurality of cells extending from a first end face to a second end face of the honeycomb unit along its longitudinal directions, the cells being separated by cell walls. A thickness of the cell walls of the first end face side is greater than a thickness of the cell walls of a center part in the longitudinal direction of the honeycomb unit; and/or a pore rate of the cell walls of the first end face side is less than a pore rate of the cell walls of the center part in the longitudinal direction of the honeycomb unit.
