| 中文摘要 |
| 为了探索提高聚丙烯腈(PAN)活性碳纤维(ACF-PAN)对SO2的吸附性能,采用加入不同的活性组分对自制的ACF-PAN进行改性;研究了ACF-PAN和经过不同改性后的ACF-PAN对SO2的吸附性能。取得改性后活性碳纤维为改性前平衡吸附量的2倍以上;为活性炭的10倍左右(ACF-PAN 62.9mg/gACF,ACF-PAN(Ⅱ)1-4型113.6-143.7mg/gACF,活性炭14.9mg/gAC)和吸附速率大于改性前的ACF-PAN的结果,由于改性大大提高了对SO2的吸附能力。 |
| 英文摘要 |
| Polyacrylonitrile-based activated carbon fiber (ACF-PAN) made by the authors in laboratory was modified by adding different active components in order to improve its performance for adsorbing SO2.Then ACF-PAN and the differently modified ACF-PANs were studied on their performances for SO2 adsorption. It was found that the modified ACF-PANs had an equilibrium adsorption capacity which was more than 2 times that of ACF-PAN and about 10 times that of activated carbon (ACF-PAN,62.9mg/g ACF; ACF-PAN(Ⅱ)1-4, 113.6-143.7mg/g ACF; AC,14.9mg/g AC),and an adsorption rate which was more than that of ACF-PAN,so that such a modification made the capacity of adsorbing SO2 to be largely increased. |
