CHEMICAL REACTOR FOR REMOVING NITROGEN OXIDE

摘要

PROBLEM TO BE SOLVED: To provide a chemical reactor with which a substance to be treated such as nitrogen oxide can be removed in high efficiency by a small power consumption when exess oxygen exists in combustion exhaust gas.

SOLUTION: This chemical reactor contains an ion-conductive phase consisting of a solid electrolyte for treating the substance to be treated by chemical reaction. An ionization reaction suppressing layer or a surface-coated layer is formed in the upstream part of a chemical reaction section of the chemical reactor in which the substance to be treated flows at first so that the ionization reaction of the surplus oxygen adsorbed on the surface of the chemical reaction section is suppressed. As a result, the power consumption of this chemical reactor can be reduced and the substance to be treated can be treated in high efficiency.
