Active carbons modified with nitrogen compounds and promoted with manganese oxides were studied as catalysts for selective catalytic reduction of NO with ammonia. The introduction of nitrogen surface species led to the increase in activity, selectivity to N2 and stability both in low (413 K) and medium (573 K) temperature region. The promotion with manganese oxides led to an additional increase in activity. However, for Mn-containing catalysts selectivity to N2 and stability stayed good only at 413 K and deteriorated strongly at 573 K.
Badanie węgla aktywnego modyfikowanego związkami azotu i manganu w reakcji redukcji tlenku azotu amoniakiem
węgiel aktywny, SCR
Węgle aktywne modyfikowane związkami azotu i manganu badano jako katalizatory w reakcji selektywnej redukcji NO amoniakiem. Wprowadzenie powierzchniowych grup azotowych zwiększyło aktywność, selektywność do N2 i stabilność zarówno w obszarze niskotemperaturowym (413 K), jak i średniotemperaturowym (573 K). Promowanie manganem prowadziło do dodatkowego wzrostu aktywności. Jednakże selektywność i stabilność pozostały korzystne jedynie w 413 K i silnie pogarszały się w 573 K.
