<p><P>PROBLEM TO BE SOLVED: To provide a nitrogen dioxide remover having excellent removing performance, being capable of retaining the performance for a long time and allowing restoration of the performance with a simple regeneration treatment, a gas-purifying method enabling efficient removal of nitrogen dioxide from an object gas by the use of the remover and a regeneration method enabling restoration of the performance of the remover with a simple regeneration treatment. <P>SOLUTION: The remover consists of an amine compound of a melting point of≥150°C without sulfo and carboxy groups, carried in a porous support. The gas-purifying method comprises treating an object gas containing nitrogen dioxide with the remover. The regeneration method comprises heating the remover having been used in the gas-purifying method at 150-250°C with a regenerating gas for the remover circulated. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
