ADSORPTIONSMATERIAL FÜR STICKSTOFFOXYDEN UND KATALYSATOR ZUR REGELUNG DER ABGASEMISSION |
| 摘要 |
An adsorption material exhibiting a superior adsorption capability relative to nitrogen oxides (NO) is constituted by a ceramic of oxide system having an average crystal diameter D, D < 500 ANGSTROM such as CeO2. A catalyst is, for example, constituted by CeO2 and zeolite and C content of CeO2 is set to satisfy 10 weight % </= C </= 80 weight %. Zeolite adsorbs hydrocarbon (HC), and HC so adsorbed is oxidized to activated CHO by CeO2. Activated CHO reduces NO adsorbed to CeO2. <IMAGE> |
