GC快速测定费托合成气中永久性气体及C1~C9烯烃、烷烃含量

Rapid Determination of Permanent Gas,C1~C9 Olefins and Alkanes in Fischer Tropsch Synthesis Gas by GC

文章利用气质联用仪研究了煤基费托合成工艺气的组成特点以及该工艺气中烯烷烃在三氧化铝毛细管色谱柱中的分离规律,明确了费托合成气中同碳数与不同碳数的烯烃、烷烃的切割时间的确认方法,利用四阀七柱系统三通道气相色谱系统实现了35 min内完成费托合成气中永久性气体及C1~C9烯烃、烷烃组成的测定。

In this paper,the composition characteristics of coal based Fischer Tropsch syngas and the separation law of alkenes and alkanes in the process gas in trialumina capillary chromatographic column were studied by GC-MS.The determination method of cutting time of alkenes and alkanes with the same carbon number and different carbon numbers in Fischer Tropsch syngas was def ined.The composition of permanent gas,C1~C9 olef ins and alkanes in Fischer Tropsch syngas was determined in 35 minutes by four valve seven column system and three channel gas chromatography system.
