摘要:
为了研究不同烟气条件下活性炭纤维(ACF)用于循环流化床(CFB)烟气脱硫脱硝的作用机理以及SO2与NO之间的吸附关系,文章通过调整CFB反应温度、入口烟气含湿量、含氧量以及SO2、NO组成等因素,测量SO2、NO的脱除效率。结果表明,反应温度主要决定脱硫时ACF的吸附类型,温度越低越利于脱硝;H2O分子能促进ACF脱硫,但过量H2O分子与SO2、NO形成了竞争吸附关系;O2能催化氧化吸附态SO2,同时将吸附态NO转化为—NO2、—NO3基团,为SO2提供吸附位点;SO2与NO在ACF表面形成竞争吸附关系,SO2能优先占据吸附位,降低脱硝效率。
Abstract:
In order to study the mechanism of activated carbon fiber (ACF) for flue gas desulfurization and denitrification in circulating fluidized bed (CFB) under different flue gas conditions and the adsorption relationship between SO2 and NO, the removal efficiency of SO2 and NO was measured by adjusting reaction temperature of CFB, the moisture content of inlet flue gas, oxygen content and the composition of SO2 and NO. The results show that the reaction temperature mainly determines the adsorption type of ACF, and the lower the temperature, the better denitration. H2O can promote ACF desulfurization, but excessive H2O molecules form competitive adsorption relationship with SO2 and NO. O2 could catalyze the oxidation of adsorbed SO2, and convert the adsorbed NO into —NO2, —NO3 groups, providing adsorption sites for SO2. SO2 and NO formed competitive adsorption relationship on the surface of ACF, SO2 could take priority to occupy the adsorption site, reducing the denitrification efficiency.
