摘要
在实验室规模的固定床反应器上,生物质炭为稻壳炭,CO2的浓度为15%~35%,O2浓度为1%~5%,反应温度恒定为900℃,研究CO2和O2对生物质炭脱硝性能的影响.结果显示:CO2浓度对生物炭脱硝性能的影响不明显,CO2浓度为25%时取得最佳脱硝率;O2能够明显抑制生物质炭的脱硝性能,O2的存在导致生物炭的脱硝率和NO选择性明显降低.
Abstract
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.
