Effect of CO2 and O2 on denitrification performance of biomass carbon
The effects of CO2 and O2 on denitration performance of biomass carbon were studied in a laboratory-scale fixed bed reactor with rice husk carbon,CO2 concentration of 15%～35%,O2 concentration of 1%～5%,and constant reaction temperature of 900℃.The results show that CO2 concentration has no obvious effect on the denitrification performance of biochar,and the best denitrification rate can be obtained when CO2 concentration is 25%.O2 can obviously inhibit the denitration performance of biomass carbon,and the existence of O2 leads to the obvious decrease of denitration rate and NO selectivity of biomass carbon.
