ADSORBENT OF NITROGEN OXIDE AND REMOVAL OF NITROGEN OXIDE USING THE SAME

摘要

PURPOSE:To obtain a deodorant efficiently removing nitrogen oxide, especially, nitrogen dioxide by compounding alumina, manganese oxide and alkali metal oxide and/or alkaline earth metal oxide in a specific ratio as the adsorbent of nitrogen oxide. CONSTITUTION:Alumina of 10-99wt.%, 70-0.5wt.% of manganese oxide and 20-0.5wt.% of alkali metal oxide and/or alkaline earth metal oxide are compounded to be formed into a desired shape. The specific surface area (BET surface area) of this adsorbent is 50m<2>/g or more and the pore volume thereof is set to 0.3cc/g or more. Since this adsorbent is effective for adsorbing and removing nitrogen oxide, especially, nitrogen dioxide, nitrogen monoxide may be preliminarily oxidized to nitrogen dioxide before brought into contact with the adsorbent.
