Porous ceramics & catalyst carriers

Catalyst carriers

Noritake's technology of controlling small pore size distributions and specific surface areas enables high activity and selectivity to be realized. Based on 30 years of experience, Noritake meets requirements for partial oxidation catalyst carriers destined for a variety of petrochemical businesses.
