摘要
煤液化残渣是煤炭清洁转化的副产物,其成分中含有多种芳香类化合物以及杂原子化合物。利用溶剂萃取技术,结合气相色谱、质谱分析,对煤液化残渣中的多环芳烃的种类与分布进行研究。结果表明,煤液化残渣正己烷萃取物中检测到18种芳香族化合物,其中7,12-二甲基苯并[a]蒽、苯并[a]芘、茚并[1,2,3-c,d]芘、苯并[ghi]苝等具有强致癌致畸性。
Abstract
Coal liquefaction residue is a byproduct from clean conversation of coal, consisting of various polycyclic aromatic hydrocarbons and heteroatom-containing compounds.Solvent extraction technology combining with gas chromatography/mass spectrometry is applied to investigate the species and distribution of polycyclic aromatic hydrocarbons in coal liquefaction residue.It is indicated that 18 kinds of aromatic compounds are identified in the n-hexane extracts from coal liquefaction residue, among which 7, 12-dimethylbenzo[a]anthracene, benzo[a]pyrene, indeno[1, 2, 3-c, d]pyrene, benzo[ghi]perylene are of high carcinogenicity and teratogenicity.
