摘要:
The present invention relates to a honeycomb catalytic converter, including: a honeycomb structured body in which multiple through-holes are arranged longitudinally in parallel with one another with a partition wall therebetween; and Pd and Rh supported on the partition walls of the honeycomb structured body, wherein the honeycomb structured body is an extrudate containing a ceria-zirconia complex oxide and alumina, a Pd-carrying region where only Pd is supported is formed on the partition walls within a predetermined width from one end of the honeycomb structured body, and a Rh-carrying region where only Rh is supported is formed on the partition walls within a predetermined width from the other end of the honeycomb structured body, and the Pd-carrying region extends to at least 50% of the length of the honeycomb structured body, and the Rh-carrying region extends to at least 20% of the length of the honeycomb structured body.
