Abstract

The invention relates to a method for producing lubricating oil base oil from hydrogenated tail oil. Using hydrocracking tail oil as raw material, it can directly carry out vacuum distillation, and under suitable conditions, lubricating oil base oil products can be obtained. The hydrocracking tail oil is made of vacuum distillate oil, solvent refined deasphalted oil and Fischer-Tropsch synthetic oil as raw materials, and uses a hydrocracking catalyst containing modified β molecular sieves. Modified β-molecular sieve with high silicon-aluminum ratio, high crystallinity, and certain secondary pores, through hydrocracking or hydrocracking process, the tail oil with pour point less than -10°C can be obtained. The invention can produce lubricating oil base oil products with excellent performance by selecting the hydrogenated tail oil processed by suitable hydrocracking catalysts without going through pour point depressing and refining processes.

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 heavy raw materials with a hydrocracking catalyst with strong isomerization function is selected to directly produce lubricating oil base oil. Background technique [0002] Traditional lubricating base oil production is based on solvent refining process, the two main steps are to use solvent refining to remove non-ideal components such as aromatics and solvent dewaxing to ensure the low temperature fluidity 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 forward higher and higher requirements on the performance of lubricating base oils. At the same time, due to the deterioration of crude oil worldwide, the amount of crude oil s...
