渣油族组成及分子结构研究进展

Research Progress of Group Composition and Molecular Structure of Residues

综述了近10年来渣油的分离与分析及渣油族组成化学结构的宏观和微观研究方法,并对这些方法的原理、特点及其应用做了详细的论述。现代分析测试技术,如光谱学、色谱学等与化学计量学相结合,为渣油组成含量的研究提供了一些新方法;质谱法、选择性化学降解法,热解法等在渣油分子细节结构的研究中不断有新的突破,几种分离分析技术的综合应用体现出了良好的分离分析效果。

The separation and analysis techniques of residual oils in recent ten years were reviewed in the paper, and the macrostructure and microstructure research methods of residue group composition were also introduced. The mechanism, characteristic and application range of these methods were discussed in detail. Modern analysis determination techniques, such as spectrum method and chromatography, combined with stoichiometry had provided a series of new methods for researching residue composition. Meanwhile mass spectrum, selectively chemical degradation technique and pyrogenation were making great breakthrough in the research of residue molecular structure. The data obtained from each technique yields different information, and the effective combination of the present available techniques can provide more useful information.
