| 微孔沸石对卷烟烟气中苯并[a]芘去除的机理研究
| | | 摘 要:本文首先从量子化学计算出发、探讨了微孔沸石吸附和催化降解苯并[a]芘(benzo[a]pyrene,B[a]P)、荧蒽(fluoranthene
Flu)和蒽(anthracene Ant)的烟草论文集可能性。微孔沸石对这些多环芳烃(Polycyclic
Aromatic Hydrocarbons, PAHs)的烟草论文集吸附和催化实验结果表明,Y型沸石能吸附和催化Flu和Ant;ZSM-5沸石能吸附和催化Ant而不能吸附Flu;NaA沸石受孔径限制,不能吸附和催化Ant和Flu。然而,将这些沸石加入到卷烟中,它们都不同程度地减少了烟气中B[a]p、Ant和Flu的含量。本文重点研究了小微孔沸石对卷烟烟气B[a]P、Flu和Ant的去除,结合理论计算推测了卷烟烟气PAHs中具有代表性的强致癌物―B[a]P在微孔沸石上的去除机理。
