采用低温微波法（60、120、180 W）和电加热法对载甲苯松木活性炭进行再生。比较了这两种再生方法下活性炭的再生效率、升温速率、能耗，并分析了再生前后活性炭的物理化学性能。结果表明：经过5次吸附—微波辐射再生之后，活性炭吸附量基本保持原有吸附量的45％。随着微波功率从60 W升高到120 W，再生时间从60 min降低到22 min，再生效率从1?7％/min增加到4?5％/min。而传统电加热再生法再生时间为180 min，是微波法的3～6倍；功率为60 W的微波加热法的升温速率为178℃/min，而电加热法升温速率只有9℃/min；从能耗角度看，微波再生法的能耗为29．7 kJ/g，而电加热法的能耗则为74．3 kJ/g；并且经检测微波法再生后活性炭的孔隙结构和官能团未发生改变。

This paper presents a comparison of low temperature microwave ( three types of microwave power were 60, 120, 180 W) and conductive heating methods for the regeneration of activated carbon loaded with toluene in terms of de?sorption rate, heating time, energy consumption and chemistry properties. The results showed that the regeneration time decreased from 60 to 22 min, with the increase of microwave power from 60 to 120 W, while the regeneration rate in?creased from 1.7% to 4.5 %/min. The time of conductive heating was 180 min, which was 3-6 times longer than that of microwave heating. The temperature rising rate for the microwave heating method with a constant power of 60 W was ap?proximately 187 ℃/min, while the temperature rising rate for the conductive heating was only 9 ℃/min. The energy consumption of microwave heating was only 29.7 kJ/g in comparison with 74.3 kJ/g of conductive heating. Moreover, the pore structure and FTIR results of the microwave regenerated activated carbon was consistent with those results of the o?riginal activated carbon.
