摘要:

以桃壳活性炭为载体，四乙烯五胺（TEPA）为改性剂，进行直接改性、HNO3氧化后改性， 考察 改性后活性炭的孔隙特征 及其对 CO2 的 吸附性能。 实验表明：改性后，活性炭的比表面积和孔容 减小 ， 孔径增大 。直接改性后，活性炭对CO2的 吸附 性能没有明显增加，HNO3+TEPA复合改性后，对CO2的 吸附 性能显著提高，303 K时，对CO2的吸附量从改性前的0.39 mmol/g提高到0.73 mmol/g。TEPA的投药量影响复合改性效果，最佳投药量为20%。

Abstract:
Study of the modification and CO2 adsorption property of peach activated carbon Porous peach activated carbon （ TAC ） was modified directly using tetraethylenepentamine (TEPA) and HNO 3 +TEPA ， and the effect of modification on TAC ’ s adsorption of CO 2 was investigated. The results show that the specific (BET) surface areas and pore volumes of TAC decrease after denaturization (oxidization process), while the pore diameter of TAC increases. Directly modified TAC by TEPA has no significant effect on CO 2 adsorption capability, however, TAC ’ s compound modification by HNO 3 oxidation plus TEPA has significant effect on CO 2 adsorption capability. The CO 2 adsorption amount of N-TEPA-TAC measured increases from 0.39 mmol/g before modification to 0.73 mmol/g at 303 K. The dosage of TEPA affects TAC ’ s modification result with the optimum dosage being 20 % 。
