Abstract: A full hydrogenation process consisted of high pressure hydrotreating, iso-dewaxing and hydrofinishing is developed by Fushun Research Institute of Petroleum and Petrochemical and adopted in industrial unit to produce high viscosity index lube base oil. It has advantages in process simplicity and low investment. APIⅡ and Ⅲ grade lube base oils as well as low aromatic solvent naphtha and white oil can be produced under appropriate conditions. The commercial results show that the products have good qualities and high added values, bringing obvious better economic benefit to the enterprise.

Key words: combined hydrogenation technology, hydrotreating, hydroisomerization, hydrofinishing
