COPPER CHA ZEOLITE CATALYSTS |
摘要 |
<p>Zeolite catalysts, systems and methods for preparing and using zeolite catalysts having the CHA crystal structure are disclosed. The catalysts can be used to remove nitrogen oxides from a gaseous medium across a broad temperature range and exhibit hydrothermal stable at high reaction temperatures. The zeolite catalysts include a zeolite carrier having a silica to alumina ratio from about 15 : 1 to about 256 : 1 and a copper to alumina ratio from about 0.25 : 1 to about 1 : 1.</p> |
