摘　　要：将胺基改性应用到沥青基球形活性炭上制备改性活性炭。分别考察了改性温度、接枝胺基种类和前处理条件对制得的改性活性炭吸附CO2能力的影响,结果表明400℃下,乙二胺氧化接枝的沥青基球形活性炭吸附CO2能力最强,吸附量可达12.35mg/g。Activated carbon has been grafted with amines and the effects of varying the adsorption temperature,the identity of the amine and the pre-treatment conditions on the CO2 adsorption properties of the resulting materials have been investigated.Activated carbon grafted with ethylenediamine at a temperature of 400 ℃ has the strongest CO2 adsorption capability,with the saturated adsorption capability reaching 12.35 mg/g.
