摘要

摘要: 利用国产的MOY分子筛对饱和烃组分中的生物标志化合物进行了柱层析分离研究,结果表明:用正己烷淋洗MOY分子筛填充的柱子可以将除去正构的饱和烃中的伽马蜡烷、甾烷、β—胡萝卜烷依次淋出,说明MOY分子筛可用于分离富集甾烷、伽马蜡烷和β—胡萝卜烷,但藿烷组分丢失。对分离组分的单体烃稳定碳同位素测定研究表明:MOY分子筛在组分分离过程中无化合物的同位素分馏现象出现,伽马蜡烷、β—胡萝卜烷的稳定碳同位素分析结果很好,但分离的甾烷因基底较高,其单体烃同位素测定重复性不理想。

Abstract: This paper investigated the column chromatography separation of biomarkers in saturated hydrocarbons by Chinese MOY molecular sieve,the results show that gammarance,steranes and β-carotane can be eluted from the column filled with MOY sieve in which n-alkanes was removed from saturated hydrocarbon.It was demonstrated that gammarance,steranes and β-carotane could be enriched,but hopanes was lost.The results of compound specific isotope analysis(CSIA)shows that there were no compounds isotopic fractionation phenomena occurred during separation.The stable carbon isotope analysis results of gammarance and β-carotane were good,while the stable carbon isotope ana-lysis results of steranes were not ideal due to its relatively high baseline.
