Research progress of extraction technology in processing different distillate by grade and composition
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 under the concept of molecular refining and realizing the transition from"fraction processing"to"component processing"is an important idea for saving energy,reduling consumption and making 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.
