Catalytic oxidation apparatus

摘要

A catalytic oxidation apparatus comprising a cylindrical honeycomb structure including a multiplicity of small passageways extending therethrough in parallel and having an oxidizing catalyst deposited thereon, a number of the passageways being separated as a catalyst regenerating zone from the other passageways, the regenerating zone being continuously shiftable throughout the entire honeycomb structure circumferentially thereof to render the honeycomb structure serviceable, from portion to portion, as the regenerating zone provided by the number of passageways.
