Cu-CHA/Fe-BEA MIXED ZEOLITE CATALYST AND PROCESS FOR THE TREATMENT OF NOX IN GAS STREAMS |
摘要 |
<p>The present invention relates to a catalyst, preferably for use in selective catalytic reduction (SCR), said catalyst comprising one or more zeolites of the BEA structure type,one or more zeolites of the CHA structure type, and optionally one or more zeolites of the MFI structure type, wherein at least part of the one or more zeolites of the BEA structure type contain iron (Fe), wherein at least part of the one or more zeolites of the CHA structure type contain copper (Cu), and wherein at least part of the optional one or more zeolites of the MFI structure type contain iron (Fe). Furthermore, the present invention concerns an exhaust gas treatment system comprising said catalyst as well as a process for the treatment of a gas stream comprising NOx using said catalyst as well.</p> |
