生物降解原油研究的新方法

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。

NEW METHODS FOR THE STUDY OF BIODEGRADED CRUDE OIL

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.
