摘要
介绍了天然沥青是一种稀有且珍贵的非常规资源,其高效利用对弥补常规能源的短缺和非常规能源的高效洁净的转化利用及相关化工产业的发展至关重要。而制约天然沥青高效利用的关键问题是缺乏对其中有机质的结构组成的认识和了解。阐述了在温和条件下对天然沥青进行可分离和非破坏的方法从分子水平上研究天然沥青中可溶有机质,及有机质组分的主要分离分析技术。随着对天然沥青有机质的组成结构深入揭示,可以为充实有机化学研究内容及对天然沥青中高附加值化学品的分离和定向转化具有深远的意义。
Natural bitumen is a rare and precious unconventional heavy petroleum resources, and their efficientutilization is not only cruciaUy important to make up the conventional resources shortage, but also to promote effective and clean utilization and conversion for unconventional resources and the high speed development of relevant chemical industry. Whereas the key issue restraining efficient utilization of natural bitumen is lack of understanding of the compositions and structures of organic components. Investigating the compositions and structures in soluble organic matter, especially using related separation and non - destructive methods uder mild conditions, from natural bitumen in molecular level based on modem separating and analytical techniques. Deep revealing the natural bitumen organic structures can provide reliable theoretical basis for enriching the knowledge of organic chemistry and develop new technologies of directly separating value - added chemicals from natural bitumen or directionally converting natural bitumen to the value - added chemicals.
