| 摘 要： | 文章在自然环境条件下对重质燃料油进行了风化模拟实验,采用气质(GC/MS)联用仪分析了重质燃料油中主要芳烃组分及其变化。结果表明:该重质燃料油中主要芳烃为苯类(C_nB)、萘(C_nN)类、菲(C_nP)类、二苯并噻吩(C_nD)类;在自然条件下,经过1周的风化,C_nB和C_0N完全损失;经过6周风化,C_1N完全损失;经过12周的风化,C_2N完全损失,3环的PAHs无明显变化。同时指出C_2D/C_2P和C_3D/C_3P的比值以及烷基化二苯并噻吩的同分异构体分布可用于区别其它油品,并且风化后变化不大,仍可较好地用于油品的鉴定。

| Abstract: | Weathering simulation of heavy fuel oil was experimented under natural conditions.Main components and changes of aromatic hydrocarbon in it were analyzed with GC/MS.The results showed that the kinds of aromatic hydrocarbon included benzene hydrocarbon(C_nB),naphthaline(C_nN),phenanthrene (C_nP)and dibenzothiophene(C_nD);CnB and C_nN almost lost after 1 week weathering experiment under natural condition;C_1N lost completely after 6 weeks;C_2N lost completely after 12 weeks while 3 rings' PAHs had no apparently changes.The value of C_2D/C_2P &C_3D/C_3P and dibenzothiophene's isomers of heavy fuel oil could be used in distinguishing this kind of oil from other kinds of oil,and it had no apparently changes after weathering which could be used to identify quality of heavy fuel oil. |
