| 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-Based ACF)〕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 m3/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.

| Abstract: | 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(m~3/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 calc... |
