Abstract: In the context of carbon peak and carbon neutral, combined with poor crude oil andabundant renewable raw material resources of China, this paper proposes that the oil refining industry can focus on the development of renewable raw materials and oil co-processing technology. Co-processing is one of the important ways for low-carbon transformation of the oil refining industry, and has a broad development prospect. This paper comprehensively discusses co-processing technology from the perspectives of its concept,raw materials, current technological status, application cases, and development prospects, aiming to provide reference for the low-carbon transformation of the refining industry.
