摘要：采用中心切割二维气相色谱,以PONA色谱柱为一维预分析柱与氢火焰离子检测器连接,以DB-35MS色谱柱为二维分析柱与MS连接,对煤直接液化加氢改质油中C7~C9馏分进行了分离与分析,并将质谱谱库检索和活数据库法相结合对60种组分进行了定性分析。同时采用标准物质和烃类化合物在PONA柱上的保留规律对上述定性结果作了验证。还采用面积归一化方法对油样中各化合物进行了定量分析和碳数分布以及族组成分析,其中C8及C9的化合物含量分别为32.3%和51.7%,主要族组成为环烷烃(77.3%)和正构烷烃(9.63%)。
Components with C7-C9 in fractions of oil prepared by direct coal liquefaction and hydrogenation were separated and analyzed by the central-cutting 2Dgas chromatography using the PONA chromatographic column as 1Dpriliminary analytical column with FID,and the DB-35 MS column as 2Danalytical column which is connected with MS;and combining with application of method of live database and searching of MS database,60 compounds were identified.The results of the identification were further verified by the regularities of retention of hydrocarbons on the PONA column and by referring to standard materials.Quantification analysis of components with various carbon numbers and grouping of various hydrocarbons were carried out by the area normalization.It was shown that relative contents of compounds with C8 and C9were found to be 32.3%and 51.7%respectively,and that the main groups of hydrocarbons found were cyclic hydrocarbons(77.3%)and alkanes with normal structures(9.63%).
