Abstract

PURPOSE: To enable the removal of NOX without using a special reducing agent and to carry out the reaction even if in the presence of O2 by removing electrochemically O2 - or O- adsorbed onto the catalytic cracking catalyst for NOX.
CONSTITUTION: Pd electrodes 2a, 2b hard to adsorb O2 are formed on both upper and lower surfaces of an oxygen ion conductor 1 which are in contact with exhaust gas and air respectively and further a composite oxide 3 which can dissociate and adsorb NOX at an oxygen ion conductor-actuating temperature is supported on the Pd electrode 2a for exhaust gas. NO is dissociated into an N atom and an O atom on the catalyst, which are adsorbed onto the catalyst. The O2 - and O- are removed by vacuum suction into the atmosphere due to the superficial oxygen ion concentration gradient or the outside electric potential gradient of the oxygen ion conductor and the surface of the catalyst is enabled to continuously adsorb NO.
