HONEYCOMB STRUCTURE, HONEYCOMB CATALYTIC BODY AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a honeycomb structure capable of providing a honeycomb catalytic body which is excellent in purification efficiency with small pressure loss and which can be mounted even in a limited space and to provide a honeycomb catalytic body which is excellent in purification efficiency with small pressure loss and which can be mounted even in a limited space and a manufacturing method of the same.

SOLUTION: The honeycomb catalytic body 50 is a flow-through type honeycomb catalytic body through which cell flow channels extend from an inlet to an outlet, both the surfaces of partition walls 4 of the honeycomb structure 1 and the inner surfaces of pores 25 carry a catalyst to form a catalyst layer 5. The catalyst carrying partition wall has permeability of 1×10-12[m2] or more, preferably 1×10-9[m2] or less.
