【Abstract】 Several kinds of bio-based lube base oil synthesis technologies with good application prospects are reviewed, including olefin metathesis, estolide, plant sugar fermentation and C-C coupling.The technical route of each kind of synthesis technology and the physical and chemical properties of corresponding lubricating oil products are briefly described.The advantage of bio-based lubricating oil is that it has good biodegradability and can realize the closed-loop process of carbon cycle, which is in line with the transformation and development of energy under the background of “double carbon” and breaks through the limitations of traditional modification technology of vegetable oil.The lubricating oil performance and process economy of bio-based lube base oil synthesis technology are comprehensively analyzed to provide reference for the industrial development of high-performance bio-based lube oil synthesis technology.At the same time, the development trend of bio-based lube oil synthesis technology in the future is analyzed and prospected.更多还原
