低环多环芳烃（萘、苊）在活性炭上的热脱附行为
摘要
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 order was 1.5, the average desorption activation energy E was 63.38 kJ/mol, and the average lnA was 11.75. The desorption kinetic model of Acp-AC was also the Avrami-Erofeev equation, the reaction order was 2, the average desorption activation energy E was 95.49 kJ/mol, and the average lnA was 16.80.
