【摘要】 利用沥青质包裹烃和沥青质钌离子催化氧化(RICO)产物中的生标对生物降解原油进行了研究。研究表明,虽然原油中的生标受到了严重破坏,但利用这两种方法在沥青质中均可以获得较为完整的生标系列。与其它方法相比,这两种方法简单方便,结果较为可靠、准确,可能是生物降解原油研究的发展方向。更多还原

【Abstract】 Entrapped hydrocarbons from asphaltene and products from the ruthenium ions catalyzed oxidation (RICO) of asphaltene were used to study the biodegraded crude oil The results indicate that the biomarkers, which are almost destroyed by biodegradation in the oil, can be recoveried from asphaltene by these two methods A fairly intergrate series of hopanes and steranes are discovered in the entrapped hydrocarbons, and a homologous series of hopanoic and steranoic acids are also detected in the RICO products Compared with other methods, these methods are simple and convenient, and the results obtained are credible and accurate Hence, these new methods are significant for the study of biodegraded crude oil更多还原
