| 摘 要： | 利用SETSYS Evolution 16型热重分析仪,在氮气气氛下分别研究了萘和苊在活性炭(AC)上的热脱附行为,并采用多升温速率法和单升温速率法相结合的方法,得到萘和苊在AC上的热脱附反应动力学方程及其动力学参数,结果表明:萘在AC上的热脱附反应动力学模型为Avrami-Erofeev方程,反应级数为1.5,脱附活化能(E)均值为63.38kJ/mol, lnA均值为11.75;苊在AC上的热脱附反应动力学模型亦为Avrami-Erofeev方程,反应级数为2, E均值为95.49kJ/mol, lnA均值为16.80.

| Abstract: | The thermal desorption behaviors of low-ring polycyclic aromatic hydrocarbons(PAHs),naphthalene(Nap) and acenaphthene(Acp),adsorbed by activated carbon(AC) were studied by the SETSYS Evolution 16 TGA in nitrogen atmosphere.The single and multiple scan methods were combined to obtain the thermal desorption reaction kinetics equations and kinetic parameters of Nap and Acp adsorbed by AC.The experimental results showed that the desorption kinetic model of Nap-AC was the Avrami-Erofeev equation,the reaction ord... |
