| titleOfInvention | Method for preparing lubricating oil base oil by processing high-wax-content raw material |
| abstract | The invention relates to a method for processing a high wax content raw material to prepare lubricating oil base oil, which comprises the following steps: the high wax content raw material firstly enters a hydrogenation pretreatment reaction zone to complete the hydrogenation saturation, the hydrogenation desulfurization, the hydrogenation denitrification and the hydrogenation deoxidation of non-alkane components in the raw material; the obtained hydrogenated pretreated oil enters a vacuum fractionating tower, and heavy oil fractions with the temperature of more than 550 ℃ are separated; the fraction with the temperature less than or equal to 550 ℃ enters a hydroisomerization reaction zone, and the hydroisomerization of the hydrogenation pretreatment oil is completed on a specific combined hydroisomerization catalyst; the obtained hydrogenation isomeric oil enters a hydrogenation refining reaction zone for further treatment to obtain a crude product; the crude product is fractionated by an atmospheric/vacuum tower to obtain base oil, diesel oil, gasoline and other products. Compared with the prior art, the method can obtain the base oil with higher yield, low pour point and high viscosity index, and has simple process and lower energy consumption. |
