Fe(II)-SUBSTITUTED BETA TYPE ZEOLITE, GAS ADSORBENT CONTAINING SAME AND METHOD FOR PRODUCING SAME, AND METHOD FOR REMOVING NITROGEN MONOXIDE AND HYDROCARBON |
摘要 |
To provide an Fe(II)-substituted beta type zeolite which has been ion-exchanged with Fe(II) ions and can effectively adsorb and remove nitrogen monoxide or hydrocarbon contained in gas to be cleaned, even if oxygen is present in the gas at a high concentration or the temperature of the gas is low. In the Fe(II)-substituted beta type zeolite, a ratio of SiO2/Al2O3 is preferably 10 to 18, a BET specific surface area is preferably 400 m2/g to 700 m2/g, a micropore specific surface area is preferably 290 m2/g to 500 m2/g, and a micropore volume is preferably 0.15 cm3/g to 0.25 cm3/g. The amount of Fe(II) supported is preferably 0.01% by mass to 6.5% by mass based on the Fe(II)-substituted beta type zeolite. |
