Abstract

PURPOSE: To increase the activity of a catalyst per unit vol. without raising gas transmission resistance by extrusion molding catalyst or carrier raw materials using dies provided with plural pins forming honeycomb-forming grooves, the surroundings of which pins at the outlet side are made uneven and rough so as to make the surroundings of the holes of the resulting catalyst uneven and rough.
