REMOVAL METHOD FOR NITROGEN OXIDE AND REMOVAL DEVICE FOR NITROGEN OXIDE

摘要

PROBLEM TO BE SOLVED: To provide a removal method for nitrogen oxide capable of simultaneously performing a removal step and a regeneration step without providing a plurality of nitrogen oxide adsorption means and continuously and efficiently removing nitrogen oxide.

SOLUTION: The removal method for nitrogen oxide includes the removal step for removing nitrogen oxide contained in a gas; and a regeneration step for regenerating nitrogen oxide removing function of the nitrogen oxide adsorption means lowered by the removal step by removing nitrogen oxide adsorbed by the solid adsorbent. The solid adsorbent includes a removal part for performing the removal step; and a regeneration part for performing the regeneration step by simultaneously performing the removal step and the regeneration step.
