摘要
用柱色谱和GC-MS方法测定了柴油的13种烃族组成,分别是:(1)链烷烃,(2)一环环烷烃,(3)二环环烷烃,(4)三环环烷烃,(5)烷基苯,(6)茚满萘满,(7)茚类,(8)萘,(9)烷基萘,(10)苊类,(11)苊烯,(12)三环芳烃,(13)胶质。采用线性最小二乘法拟合得到了柴油的十六烷值和密度与其13个烃族组成的关联式,统计检验结果并将计算值与实验值进行比较,结果表明,用烃族组成预测柴油的十六烷值和密度能够得到令人满意的结果。
The hydrocarbon groups of diesel fuel were separated and determined by liquid chromatographic method and (GC-MS),including paraffins,monocycloparaffins,dicyclopara (ffins),tricycloparaffins,alkylbenzenes,benzocycloalkanes,indenes,naphthalenes,naphthocycloalkanes,acenaphthenes,acenaphthylenes,triaromatics and resin.The cetane number and density were correlated with these thirteen hydrocarbon groups by multiple linear regression method.The statistic results and the comparison of the calculated and the observed values indicated that the correlation equation could satisfactorily predict the cetane number and density of diesel fuel from its hydrocarbon groups.
