| Popis: |
NOx reduction under simulated lean burn conditions was studied using a non-thermal plasma in combination with zeolite and alumina catalysts. The influence of temperature and plasma treatment on the catalytic performance was investigated. Zeolite catalyst B showed high activity in the 150-300 degree Celcius temperature region. Alumina Catalyst D was most active at temperatures higher than 250 degrees Celcius. In addition, the alumina catalyst was effective in oxidation of aldehydes formed during plasma treatment of the reaction mixture. When the reaction was carried out over a catalyst bed consisting of separate layers of the zeolite and alumina catalyst, the catalyst temperature range for significant NOx reduction was expanded to 150-500 degrees Celcius. |
