摘要
分别采用HNO3改性、高压水热改性、NaOH改性3种不同的方法制备活性焦吸附剂,通过烟气脱除的实验装置对其脱硫脱硝性能进行评价,并利用工业分析和元素分析、场发射扫描电镜(SEM)、傅里叶红外光谱(FT-IR)、比表面积(BET)及孔结构分析对各样品进行表征。结果表明,HNO3改性的活性焦脱硫脱硝效果均最佳。
Abstract AC adsorbent is prepared respectively with HNO3, high pressure hydrothennal and NaOH. The experimental e- quipment is used to evaluate desulfurizafion and denitritlcation performance and the samples are characterized by proximate and ultimate analysis,SEM,FT- IR and BET. The results show that the removing direct of AC modified by HNOa oxidation is perfect.
