在N_2气氛下,采用卧式管式炉以10 ℃/min的升温速率对塑料、厨余类和未分类生活垃圾在600,700,800 ℃下进行热解。同时,对城市生活垃圾进行热重分析,对热解前后垃圾中的氯含量进行元素分析;以NaOH溶液吸收热解过程中产生的HCl,并用硝酸银滴定法进行测定。结果表明,塑料垃圾的氯含量最高,而厨余垃圾的氯含量最低;垃圾热解过程中,HCl析出量随着温度的上升而增加,残余焦炭中的氯含量随着温度的上升而减少。在升温过程中,HCl的最大析出速率均在400 ℃左右,600 ℃以后HCl的析出速率再次增加。未分类垃圾热解过程中的HCl析出率最高,厨余垃圾最低;低温热解及对含氯量相同的垃圾进行分类热解,有利于控制...

The releasing behavior of HCl in N2 atmosphere at diffenrent final temperatures( 600 ~ 800 ℃)during municipal solid wastes( MSW) pyrolysis process was investigated using horizontal tube furnaces pyrolysis system at heating rate of 10 ℃/min. The HCl was absorbed by NaOH solution and the quantified by AgNO3 titration. The results show that the chlorine content in plastic waste is highest,whereas the kitchen waste is lowest. The quantity of HCl is increase with increasing prolysis temperature,and the contents of Cl in pyrolysis char are the oppo...
