Honeycomb catalyst body, precoat carrier for manufacturing honeycomb catalyst body, and method for manufacturing honeycomb catalyst body

摘要

The honeycomb catalyst body of the present invention includes a porous partition wall having a large number of pores arranged so as to form a plurality of cells communicating between two end faces, and the cells are arranged at any one of the end faces. A honeycomb catalyst body comprising a catalyst layer containing a catalyst supported on at least an inner surface of the pores of a honeycomb structure provided with a plugging portion arranged to be sealed, the honeycomb structure The mass (g / cm 3) of the catalyst layer per unit volume (1 cm 3) of the body is 60% or less of the volume (cm 3 / cm 3) of the pores per unit volume (1 cm 3) of the honeycomb structure.
