在管式炉实验平台上研究 O2 /CO2 气氛下反应温度、吸收剂种类、气氛、钙氯比以 及燃料混合比等因素对木屑与 PVC 混烧过程中脱氯效率的影响，结果表明: 随温度的升 高，脱氯效率先增大后减小，在 700℃时获得最高的脱氯效率( 71. 4%) ; 添加剂比例及种 类也会对脱氯产生一定的影响，改性 CaCO3 的孔隙结构更加丰富，比表面积相对增大，在 高温下具有较高的脱氯率;随着混合物中木屑比例的上升，脱氯率有所增大; O2 /CO2 气氛 下的脱氯率大于 O2 /N2 气氛下的脱氯率． 对吸附剂和燃烧产物进行的 BET 和 SEM/EDS 分析表明:产物颗粒表面覆盖着一层致密的 CaCl2，阻止了 HCl 穿透颗粒表面进入脱氯剂 内部的充分反应，使脱氯效率降低． 

types of absorber，atmosphere， ratio of calcium to chlorine，and fuel mixture ratio on the dechlorination of wood chips and PVC during cofiring under O2 /CO2 atmosphere were investigated by using a tube furnace． The results show that with the increment of the temperature， the dechlorination efficiency increases firstly and decreases subsequently． Meanwhile， the highest dechlorination efficiency is 71. 4% at 700℃． The ratio of additives has a certain impact on dechlorination． Modified calcium carbonate can increase the dechlorination rate at a high temperature，because the pore structure becomes more abundant and the specific surface area becomes relatively larger． As the mixing ratio of sawdust rises，the dechlorination efficiency increases， and the dechlorination efficiency in O2 /CO2 atmosphere is higher than that in O2 /N2 atmosphere． The analysis of BET and SEM/EDS on sorbent and product indicates that the surface of the product particle covers the layer of dense CaCl2，which prevents the HCl from penetrating the particle surface into the dechlorination agent inside the full reaction． The reaction becomes inadequate，which leads to the reduction in dechlorination efficiency．
