石油中金属卟啉分离和分析方法的研究进展

RESEARCH PROGRESS OF SEPARATION AND ANALYTICAL METHODS FOR METALLOPORPHYRINS IN PETROLEUM

石油中金属元素会对石油加工造成不利影响,有些金属元素可以通过电脱盐等方式除去,而金属卟啉化合物则很难脱去。金属卟啉化合物结构复杂,一般都富集在胶质和沥青质中,随着分析技术的发展,逐渐对金属卟啉化合物有了全面的认识。系统总结了金属卟啉化合物分析方法的研究进展,概述了各种分离和表征方法的特点,并对金属卟啉分子结构的新分析方法研究方向进行展望。

Metal elements in petroleum can adversely affect petroleum processing.Some metal elements can be removed by electrodesalination,while the metal porphyrin compounds are more difficult to remove.Metal porphyrin compounds have complex structure and generally concentrated in colloid and asphaltene.With the development of analytical technology,a comprehensive understanding of the metal porphyrin compounds has been gradually gained.This paper systematically summarized the research progress of analytical methods for metal porphyrin compounds,outlined the characteristics of various separation and characterization methods,and gave an outlook on the direction of research on the molecular structure of metal porphyrins by new analytical methods.
