Abstract

A ceramic catalytic convertor catalyst support (12) comprises an elongated open-porous matrix (26) containing a catalyst supported in its interior and provided with lengthwise passages (28) opening out at an end (30, 32) of the matrix. Each passage (28) is constricted (34) nearer to the end of the matrix opposite the open end of the passage, some passages (28.1) opening out of one end (30) of the matrix and some (28.2) opening out of the other end (32) of the matrix. The constrictions (34) in the passages act to promote flow of gas, entering open ends of the passages (28.2) at one end (32) of the matrix, in a direction transverse to the passages and through the porous interior of the matrix into passages (28.1) having open ends at the opposite end (30) of the matrix.
