重油分子结构组成的分析方法研究进展

Progress in research analysis methods of molecular structure of heavy oil

综述了近年来重油分子结构的研究方法,分别介绍了烃类化合物、胶质和沥青质及氧、氮、硫杂原子化合物结构组成的分析方法,并分析比较了不同分析方法的优缺点。质谱法、钌离子催化氧化法、裂解色谱法等在研究重油分子结构中不断有新的突破,各种分析手段的结合为重油分子结构组成提供更加准确、丰富的信息。

The research analysis methods of molecular structure of heavy oil were introduced. Respective-ly,the analysis methods of hydrocarbons,colloid and asphaltene and oxygen-,nitrogen-,and sulfur- contai-ning heteroatom compounds in heavy oil are reviewed. It also compares the advantages and disadvantages of various and analysis main methods. Meanwhile mass spectrum,ruthenium（Ⅷ）ion catalyzed oxidation technique and pyrolysis chromatography were making great breakthrough in the research of heavy oil mo-lecular structure. The combination of various analysis methods for heavy oil molecular structure can pro-vide more accurate and abundant information.
