通过对废弃粉末活性炭(WPAC)进行热解再生实验,采用热重(TG)、红外分析(FTIR)、表面分析(BET)、 X射线衍射(XRD)表征手段,分析了废弃粉末活性炭热解再生前后的比表面积、孔隙结构及再生过程中有机物分解的初步规律。同时比较了废弃粉末活性炭再生前后对亚甲基蓝(MB)的吸附性能,对WPAC热解再生效果进行了评价。实验得出的最佳热解再生条件是以氮气为载气,热解温度650℃,热解时间2h。在此再生条件下,再生炭(RPAC)的比表面积为1161.4m~2/g,恢复到新鲜活性炭的94.5%;废弃粉末活性炭再生前后对亚甲基蓝的吸附等温线符合Langmuir模型,吸附容量为420.5mg/g,恢复到新鲜炭的89.6%。由此结果表明,WPAC经热...

The effect of pyrolysis regeneration on the specific surface area, pore structure and the decomposition of organic matter of waste powdered activated carbon(WPAC)was studied through X-ray diffraction(XRD), Fourier transform infrared analysis(FTIR), BET and thermo-gravimetric analysis(TG). Meanwhile, the adsorption capacity of waste powdered activated carbon were analyzed before and after pyrolysis. The optimal pyrolysis conditions as follow: N2 as carrier gas, the regeneration temperature and the time of pyrolysis is 650℃and 2h respectively. Under this condition, BET surface area of RPAC...
