| 摘 要： | 利用低温等离子体（NTP）净化车用柴油机尾气中的颗粒相多环芳烃（PAHs），基于电晕放电的原理，设计了NTP发生装置。使用色谱质谱联用仪分析经过NTP净化前后柴油机尾气中颗粒相多环芳烃的含量，观察NTP对颗粒相多环芳烃的净化效果。结果表明，颗粒相小分子量PAHs除菲、蒽外，其他4种多环芳烃的含量显著增加，其中萘、苊变化率达1 130.4%和758.57%；大分子量PAHs除苯并（ghi）芘外，多环芳烃的含量降低达80%以上；NTP对柴油机尾气中颗粒相多环芳烃含量及毒性当量的净化率分别达58.4%和82.8%。

| Abstract: | Particle-phase polycyclic aromatic hydrocarbon (PAH) emissions from a diesel engine were purified with non-thermal plasma (NTP) technology. The NTP reactor was designed based on a corona discharge. PAHs both with and without NTP were quantified with gas-chromatography mass spectrometry (GC-MS). The levels of PAHs were analyzed based on GC-MS results. The results showed that the content of PAHs increased greatly for light particle-phase PAHs except for Phe and AnT. The increases in the percentage of NaP and AcPy were 1130.4% and 758.57%, respectively. The decrease in heavy PAHs exceeded 80%, except for BghiP. The content and BaPeq of the PAHs with and without NTP dropped to 58.4% and 82.8%, respectively. |
