摘要:

解决传统燃料过剩、开发绿色高效低耗的油品加工技术是双碳背景下的必然趋势。发展分子炼油理念下的变革性加工技术,实现从“馏分加工”到“组分加工”,是节能降耗、物尽其用的重要思路。其中,组分的高效分离是实践分子炼油理念,实现精细化加工的重中之重。详细介绍了我国各种馏分油的化学组成的分布规律以及现有溶剂萃取技术在分离芳烃、烷烃和杂原子化合物等组分的研究现状,讨论了各类油品由于组成差异而导致不同的分离难点,旨在提出未来研究的切入点和有价值研究方向。

Abstract:

It is an inevitable trend to solve the excess of traditional fuel and develop green, efficient and energy-saving oil processing technology under the background of dual carbon. Developing transformative processing technology based on the concept of molecular refining and changing processing mode from "fraction" to "component", is an important idea to save energy, reduce consumption and make the best use of materials. Among them, the efficient separation of components is the most important thing to practice the concept of molecular refining and achieve fine processing. The distribution regular of chemical composition of various distillates in China and the current research status of solvent extraction technology in separating arenes, alkanes and heteroatomic compounds are introduced in detail. The separation difficulties caused by composition differences of various oil are discussed, aiming to put forward the pointcut and valuable research direction in the future.

Key words: distillate, separation, solvent extraction, arene, alkane, heteroatomic compound
