Xiang ying analysis technology co., LTD., established the iron-based catalyst fischer-tropsch synthesis product water phase low carbon (C1 ~ C8) alcohol, aldehyde, ketone of XiangyingGC7990plus gas chromatographic method. The chromatographic separation conditions were optimized, established on the basis of ethanol material combined with each branch is factor quantitative methods; Investigates the precision and accuracy of the method, and the fischer-tropsch synthesis water product samples were determined. Results show that the content of ethanol in different range show good linear relationship, the correlation coefficient were greater than 0.99. Fischer water product of standard addition between 93.4% ~ 109.6%, the recovery accuracy can meet the needs of practical analysis. Actual fischer-tropsch synthesis of water product, and the analysis results show that the fischer-tropsch synthesis in aqueous phase product main low carbon alcohol, aldehyde, ketone of total mass fraction is about 3% ~ 12%, the highest ethanol content (about 1.7% ~ 1.7%), and is constitutive alcohol, heterogeneous alcohol and aldehyde ketone compounds accounted for the total ratio of reduced in turn. This method is simple, fast, for fischer-tropsch synthesis in aqueous phase product component analysis has important significance.
滕州市翔鹰分析技术有限公司建立了铁基催化剂费托合成反应水相产物中低碳（C1~C8）醇、醛、酮的XiangyingGC7990plus气相色谱测定方法。对色谱分离条件进行了优化，确立了以乙醇为基准物质并结合各组分校正因子的定量方法；考察了方法的精密度和准确度，并对费托合成反应水相产物样品进行了测定。结果表明，乙醇在不同的含量范围内呈现良好的线性关系，相关系数均大于0.99。费托合成水相产物中的加标回收率在93.4％~109.6％之间，准确性可以满足实际分析的需要。实际费托合成水相产物的分析结果表明，费托合成水相产物中主要的低碳醇、醛、酮的总质量分数约为3％~12％，乙醇含量***高（约为1.7％~7.3％），且正构醇、异构醇和醛酮类化合物所占的总比率依次降低。该方法简单、快速，对费托合成水相产物中重要组分的分析有重要意义。
