Selective catalytic reduction of NOx by hydrocarbons enhanced by hydrogen peroxide over silver/alumina catalysts

摘要

It is shown that hydrogen peroxide enhances substantially selective reduction of NOx to nitrogen with hydrocarbons over Ag/alumina catalysts.Ag/alumina is one of the promising catalysts for selective catalytic reduction of nitrogen oxides to nitrogen (SCR-NOx) by hydrocarbons,providing high and stable activity at temperatures >350 deg C when using long-chain paraffins (the main components of diesel fuel) as reductants.
