Abstract: The low sulfur and low aromatic light white oil production technology developed by Dalian Research Institute of Petroleum and Petrochemicals (FRIPP) was introduced, where the bench scale high-pressure hydrogenation device was adopted and the diesel fraction was used as material. The commercial application results showed that at conditions of PH2 pressure of 15.0 MPa, hydrogen-to-oil ratio 800 (v), reaction temperature of 60 ℃+base, and the optimized liquid space velocity, the mass fraction of the aromatics is 0.004%, 0.007%, 0.015%, 0.021%, 0.046% for 160-18 ℃, 185-215 ℃, 215-245 ℃, 245-280 ℃, 280-310 ℃ fractions, respectively, all meeting with the industry standard of NB/ST/T 0913-2015（Light White Oil II）. The fraction heavier than 310 ℃ gives pour point of －9 ℃ and Saybolt color of ＋30，meeting the industry standard of NB/SH/T 0006-2017( Industrial Mineral Oil II).
