摘　　要：对煤基活性炭、坚果壳活性炭和椰子壳活性炭三种不同的活性炭进行N_(2)物理吸附-脱附和傅里叶红外光谱表征分析,研究其吸附乙硫醇性能,并考察椰子壳活性炭吸附乙硫醇过程中各变量的效能影响。结果表明,活性炭结构以微孔为主,此外还有部分含氧官能团;煤基活性炭在10 min左右开始穿透,50 min左右达到饱和;椰子壳活性炭穿透时间为30 min,60 min左右达到吸附饱和,对乙硫醇的吸附能力最强;椰子壳活性炭吸附性能最好的条件为湿度80%,初始浓度5 mg·L^(-1),流量400 mL·min^(-1),温度15℃,此时椰壳活性炭的吸附量达到最高。Three different activated carbons,coal based activated carbon,nut shell activated carbon and coconut shell activated carbon,were characterized by N_(2) physical adsorption-desorption and Fourier transform infrared spectroscopy to study their adsorption performance of ethanethiol,and the effects of various variables in the process of coconut shell activated carbon adsorption of ethyl mercaptan were studied by using the control variable method.The results show that the structure of activated carbon is mainly microporous,and having some oxygen-containing functional groups.Coal activated carbon began to penetrate in about 10 minutes and reached saturation in about 50 minutes.The penetration time of coconut shell activated carbon is 30 min,and the adsorption saturation is reached in about 60 min.The adsorption capacity of coconut shell activated carbon for ethyl mercaptan is the strongest.The best conditions for the adsorption performance of coconut shell activated carbon are humidity 80%,initial concentration 5 mg·L^(-1),flow rate 400 mL·min^(-1) and temperature 15℃.Under the above conditions,the adsorption capacity of coconut shell activated carbon reaches the highest.
