The analysis of alkylbenzothiophenes (alkyl-BT) and alkyl-dibenzothiophenes (alkyl-DBT) in light cycle oil (LCO) and straight run (SR) gas oils is described. A detailed identification and quantitative analysis of alkyl-BT and alkyl-DBT present in LCO gas oils was carried out using GC-SCD. For the SR gas oils, the simultaneous presence of thiophenic and nonthiophenic compounds does not allow for a selective analysis of thiophenic compounds by GC-SCD. A new method using gas chromatography coupled with high-resolution mass spectrometry (GC-HRMS) is proposed to selectively detect and quantify the alkyl-BT and alkyl-DBT in SR gas oils. The development of the method and comparison of results between GC-SCD and GC-HRMS are presented.
描述了轻质循环油（LCO）和直馏（SR）瓦斯油中烷基苯并噻吩（alkyl-BT）和烷基二苯并噻吩（alkyl-DBT）的分析方法。使用气相色谱-硫化学发光检测器（GC-SCD）对LCO瓦斯油中存在的烷基-BT和烷基-DBT进行了详细的鉴定和定量分析。对于SR瓦斯油，噻吩类和非噻吩类化合物同时存在，使得无法通过GC-SCD对噻吩类化合物进行选择性分析。提出了一种使用气相色谱与高分辨率质谱联用（GC-HRMS）的新方法，用于选择性检测和定量SR瓦斯油中的烷基-BT和烷基-DBT。介绍了该方法的开发以及GC-SCD和GC-HRMS之间的结果比较。
