摘　　要： 采用动态吸附试验,利用自制的试验装置研究了黏胶基活性炭纤维〔Viscose-Based Activated Carbon Fibre（Viscose-BasedACF）〕对三氯一氟甲烷（CFC-11）气体的吸附效果.在进口ρ（CFC-11）为0.5～8.0 mg/L,空塔气速为0.2 m/s,气体体积流率为0.72 m^3/h的条件下,计算出黏胶基活性炭纤维对CFC-11气体的吸附,容量为0.788 g/g,传质区高度为0.077 2 m,全床层饱和度为65.47%,并作出活性炭纤维（AFC）的穿透曲线.用Freundlich方程对等温吸附曲线进行拟合显示,进口ρ（CFC-11）在0.5～8.0 mg/L时,Freundlich方程较好地拟合了等温吸附曲线,且便于实际计算. Adsorption behaviors of CFC-11 organic emissions on viscose-based activated carbon fiber（Viscose-Based ACF） were studied in self-made experimental devices using dynamic adsorption experiments with inlet concentration 0.5-8.0（mg/L）,superficial gas velocity 0.2（m/s） and gas volume flow rate 0.72（m3/h）.The breakthrough curve of adsorption for CFC-11 on the Rayon-based ACF was obtained.Based on the test results,the adsorption capacity of Rayon-based ACF,height of mass transfer zone and bed saturation were calculated to be 0.788（g/g）,0.0772 m and 65.47%,respectively.Adsorption isotherms were fitted by the Freundlich equation.The results showed that when the CFC-11 inlet was between 0.5-8.0（mg/L）,the Freundlich equation showed good agreement with the adsorption isotherm.
