HONEYCOMB CATALYTIC STRUCTURE, PRECOATED SUPPORT FOR PRODUCING HONEYCOMB CATALYTIC STRUCTURE, AND PROCESS FOR PRODUCING HONEYCOMB CATALYTIC STRUCTURE

摘要

According to the present invention, there is provided a honeycomb catalytic structure comprising:
a honeycomb structure comprising porous partition walls having a large number of pores, disposed so as to form a plurality of cells extending between the two end faces of the honeycomb structure and plugging portions disposed at either one end of each cell, and
a catalyst layer containing a catalyst, supported at least on the inner surfaces of the pores of the honeycomb structure,
wherein the mass of the catalyst layer per unit volume (1 cm 3 ) of the honeycomb structure (g/cm 3 ) is 60% or less of the volume of pores per unit volume (1 cm 3 ) of the honeycomb structure (cm 3 /cm 3 ).
