Abstract

The present invention provides method of producing base oil for lubricant oil with hydrogenated tail oil. Hydrogenated tail oil as material is treated through one white clay refining process or one medium pressure hydrogenating and refining process under proper condition to obtain the lubricant oil base oil product. The hydrogenated tail oil is produced with vacuum gas oil, refined solvent oil or Fischer-Tropsch synthesized oil as material and through hydrocracking or hydrotreating process under the action of hydrogenating catalyst, and has pour point lower than -10 deg.c. The lubricant oil base oil product has excellent performance.

Description

technical field [0001] The invention relates to a method for producing lubricating oil base oil from hydrogenated tail oil. The hydrogenated tail oil obtained by treating with a hydrogenation catalyst with a strong isomerization function is selected for direct clay refining or medium-pressure hydrogenation supplementary refining to produce lubricating oil base. oil method. Background technique [0002] The traditional production of lubricating oil base oils adopts solvent refining process. The process of producing base oils with this solvent refining process has a history of nearly a century. The main two steps are still solvent refining to remove non-ideal components such as aromatics and Solvent dewaxing to ensure the cold flow properties of the base oil. In addition, white clay or hydrogenation supplementary refining is generally carried out. [0003] The increasingly stringent environmental regulations and the rapid development of the machinery industry have put forwar...
