Catalytical reduction of NOx over granular active carbon nanocatalysts impregnated with copper oxide

NO and NO2 play a major role in the formation of ground level ozone, photochemical smog and acid rain. According to these biological threats, some techniques must be applied to reduce the disturbing consequences of industrial life. In this work the selective catalytic reduction (SCR) with NH3 and activity of copper loaded on granular active carbon (GAC) has been studied. The catalysts prepared by impregnation method in 1,3 and 7 percent metal loaded onthe GAC as support. The aim was to study efficiency of copper on the catalyst’s reductive activity and selectivity of the catalyst for Nitrogen.The outlet gas measured by a semi-online gas chromatograph. Among all the catalysts studied, the one with 3% copper loaded on granular activated carbon was the most suitable in NOx reduction.
