HONEYCOMB STRUCTURE AND HONEYCOMB CATALYTIC SUBSTANCE

摘要

A honeycomb structure 1 includes porous partition walls 4 having a large number of pores and disposed so as to form a plurality of cells 3 each extending between the two ends 2a, and plugged portions 10 disposed so as to plug the inside of the cells 3 at either one end of the honeycomb structure or at the insides of the cells, wherein the honeycomb structure 1 has the partition walls 4 having a permeability of 7x10 -12 to 4x10 -8 m 2 . The honeycomb structure can provide a honeycomb catalyst structure which is superior in purification efficiency, is low in pressure loss and can be mounted even in a limited space.
