DeNOx Cu/Carbon Xerogels

Résumé

Carbon materials with different pore texture have been prepared by evaporative drying and pyrolysis of resorcinol-formaldehyde aqueous gels. These carbon xerogels have been characterised and used as copper catalyst supports in the Selective Catalytic Reduction of NO by NH3 at low temperature. Without metal, some activity is observed due to reaction between NO and NH3, but the NO conversion is strongly enhanced after copper introduction. High deNOx efficiency was obtained on these Cu/carbon xerogels at very low temperature and some pore texture effect was observed. However, special cares have to be taken to avoid carbon consumption and preserve its surface by keeping reaction temperature below 215oC.
