Abstract

The review discusses currently relevant methods for studying petroleum resins. A significant proportion of the research work deals with the study of resins in heavy oils, for which experimental approaches have been systematized and the possibilities and limitations of the mass spectrometric, spectroscopic, X-ray, and chromatographic methods have been discussed. Published data on the effect of resins on the stability of asphaltenes in heavy oils and other petroleum stocks has been analyzed. In addition to experimental approaches, an important factor for understanding the role of resins in the aggregation of asphaltenes is studying their intermolecular interactions using quantum-mechanical calculations. Commonly known approaches to the concentration, fractionation, and purification of heteroatomic petroleum components from heavy oil resins using extraction and chromatographic methods for the isolation of chemical compounds from complex multicomponent mixtures have also been considered.

重油树脂的组成和性能

摘要

该评论讨论了目前有关研究石油树脂的方法。大量研究工作涉及重油中树脂的研究，为此已将实验方法进行了系统化，并讨论了质谱，光谱，X射线和色谱方法的可能性和局限性。分析了有关树脂对重油和其他石油库存中沥青质稳定性的影响的公开数据。除了实验方法外，了解树脂在沥青质聚集中的作用的重要因素是使用量子力学计算研究它们的分子间相互作用。浓缩，分馏，
