废弃粉末活性炭热解再生实验及表征分析
Experimental and characteristic analysis on pyrolysis regeneration of waste powdered activated carbon
摘要
Abstract
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:N2as carrier gas,the regeneration temperature and the time of pyrolysis is 650℃ and 2h respectively. Under this condition, BET surface area of RPAC could be recovered to 1161.4m2/g which was 94.5% of fresh activated carbon. Langmuir model could well describe the adsorption isotherm of methylene Blue. The adsorption capacity of RPAC for the methylene blue was 420.5mg/g which was 89.6% of fresh activated carbon. The results showed that the surface chemical property,pore structure of WPAC and adsorption capacity could be effectively recovered through pyrolysis.关键词
