摘要: 建立了乙烷氧化脱氢制乙烯原料气及反应产物的气相色谱分析方法。反应样品包括七种组分(O2,N2,CH4,C2H4,C2H6),在一根色谱柱上不能得到很好的分离,该法改装色谱气路。将两极色谱柱并联,使用两个串联的热导池,获得了满意的分离,重现性好。该方法定量准确、简便迅速。Abstract: This paper introduces a gas chromatographic method for quantitative determination of feed gas and products of oxidative dehydrogenation of ethane to ethene. The product components includes O 2,N 2,CH 4,CO,CO 2,C 2H 4 and C 3H 6. This method uses t
