Key words: hydrogenation; Clean solvent oil; technology 1 words before The application of special solvent oil is widely used in textile printing and dyeing, vegetable oil extraction, paint, makeup, aluminum foil rolling, printing and pesticide And other industries. Low grade solvent oil, which contains more sulfur, nitrogen and aromatic hydrocarbons, can produce pungent odors in use The harm to the human body. Depth removal is the key to solving this problem. As the consciousness of environmental protection is strengthened, the ring With the improvement of the regulations, the production of solvent oil is gradually developing in the direction of low sulphur and low aromatic hydrocarbons. Solvent oil refining commonly used square The method is an acid base white clay refining or hydrogenation. In this case, the acid alkali white soil refining method is poor, and the process produces acid residue. The use of the method is limited by pollutants such as alkali residue and low yield. The hydro-refining process can effectively remove the sulfur, Nitrogen and aromatic hydrocarbons and other impurities, the solvent oil products have good quality, can produce high-grade, odorless solvent oil, the production process has no special environmental protection The problem is widely applied. In the present world, the low aromatic solvent oil of Exxon
