승화법으로 제조된 새로운 Pt/ZSM-5의 NO 선택적 촉매 환원반응 활성 |
| 초록 |
Pt/ZSM-5 catalysts with 9.85 wt% and 0.34 wt% of Pt, were prepared by sublimation of PtCl2 with CO into H-ZSM-5. Pt(CO)2Cl2 was made and sublimed upon the addition of CO to PtCl2. They showed a high activity for the selective catalytic reduction of NO to N2 and especially wide temperature window. Pt/ZSM-5-98 has two kinds of active sites. One site has the maximum conversion at 250 oC and was not affected by the pretreatment, the kind of hydrocarbon and the addition of H2O and/or SO2. The other site has the maximum conversion above 300 oC and was affected by the pretreatment condition and the kind of hydrocarbon. The site was deactivated by SO2.
