摘要
本文介绍了一种新的热裂解乙烯气在线多维色谱分析系统。采用一次进样、自动阀切换技术、TCD和FID双检测器检测、归一化方法定量,用一根氧化铝填充玻璃毛细管柱和三根填充柱,约75分钟完成水蒸汽热裂解气样中包括碳戊烯的全组成分析。整个系统具有分析结果重复性好、准确度高、操作方便、提供的组成信息全面等特点。
An in-line multidimensional GC system for analysing gaseous product from steam cracks has been developed. The system includes one alumina packed capillary column and three packed columns combined with three valves and an HP 19405A SECM. All components in steam cracking gases, including individual pentenes, can be determined in 8 single run by. normalization when a TCP and a FID were used as the detectors. Repeatability and accuracy of this method are alsq given.
