SCR of NO with natural gas over layered oxide-zeolite catalyst in the presence of SO2, H2O and excess O2 |
| 초록 |
SCR of NO with natural gas in the presence of excess O2, H2O and SO2 is studied over layered oxide-zeolite catalyst. The addition of modified layered oxide can improve the catalytic activity of Pd/H-ZSM-5 catalyst for the SCR of NO with natural gas in the presence of excess O2, H2O and SO2. Not only highly dispersed PdO and Pd2+ or the Bronsted acid site but also Lewis acid site in Pd/H-ZSM-5 is active sites for SCR of NO. It seems that modified layered oxide can retard the thermal decomposition of Pd-species and enhance durability against SO2 poisoning in the presence of excess O2 and H2O. |
