Preparation of active coke combining coal with biomass and its denitrification performance
To improve the selective catalytic reduction of NO with NH3 over active coke (AC), coal–biomass ACs were prepared from the mixture of poplar and 1/3 coking coal for increasing the active sites. The resultant ACs ...
