The waste lubricating oil is the lubricating oil replaced in the use process of mechanical equipment. Due to the action of high-temperature oxidation, thermal decomposition, shearing abrasion and the like, light fractions, condensation compounds, colloids, asphaltenes, carbon particles and impurities such as fuel oil, metal abrasive particles and the like are generated in the lubricating oil. With the development of economy, particularly the development of the automobile industry, the demand for lubricating oil is increasing, and the amount of waste lubricating oil products produced each year is also increasing year by year. China, the second lubricating oil in the world, consumes millions of tons every year, and the waste lubricating oil is discarded into the environment, so that serious environmental pollution is caused. Therefore, after the waste lubricating oil is treated by a reasonable process and deterioration components and external pollutants are removed, the waste lubricating oil is changed into valuable, and huge economic benefits and ecological benefits can be brought to the society no matter from the aspect of recycling energy resources or environmental protection.
