采用柱阀切换技术消除裂解碳五馏分烃类组成的测定干扰

Column valve switching technology to eliminate interference in determination of hydrocarbon composition of cracked C5 fraction by GC

介绍了一种采用柱阀切换和独立控温技术的气相色谱测试方法,利用该方法可以实现对裂解碳五馏分中烃类组成的测定,试验结果表明该测试方法具有灵敏度高,分析结果准确的特点,解决了裂解碳五馏分烃组成测定中碳四和碳五组分相互干扰的问题,能够为裂解碳五馏分质量监测提供参考数据。

The gas chromatography test method with column valve switching and independent temperature control technology can be used to determine the hydrocarbon composition in cracked C5 fraction. The test results show that the test method has high sensitivity and accurate analysis results. It solves the problem of mutual interference between cracked C5 fraction hydrocarbons and carbon four EPA assay components,and can provide reference data for quality monitoring cleavage of cracked C5 fraction.
