Embodiment 1

[0019] A process for improving the quality of lubricating base oil, comprising the steps of:

[0020] (1) The clay is activated with dilute sulfuric acid with a mass fraction of 8%, washed with water, dried and pulverized to obtain activated clay.

[0021] (2) Add the refined oil into the clay tank, and heat up to 90°C, add activated clay with a mass fraction of 15% and stir for 25 minutes, pass the refined oil through the degassing tower, and then raise the temperature of the refined oil to 115 °C, add a zinc soap stabilizer with a mass fraction of 3‰ to the refined oil, stir for 15 minutes, and filter to obtain a lubricating oil base oil.

[0022] (3) Blend the above lubricating oil base oil into lubricating oil, and apply the lubricating oil to the places that need to be lubricated.

[0023] According to a process for improving the quality of lubricating oil base oil in Example 1, when adding a stabilizer in the production process, strictly control the temperature, stirrin...

Embodiment 2

[0025] A process for improving the quality of lubricating base oil, comprising the steps of:

Abstract

The invention relates to a technology for improving the quality of lubricant base oil. The technology includes the following steps that refined oil is added into a white clay pot and heated to 90 DEG C-100 DEG C, white clay is added, the mixture is stirred for 25 min-35 min, the refined oil passes through a degassing tower and then is heated to 115 DEG C-125 DEG C, a stabilizer with the mass fraction of 0.3%-0.5% is added into the refined oil, and the mixture is stirred for 15 min-25 min and then filtered to obtain the lubricant base oil. According to the technology for improving the quality of the lubricant base oil, by adding the stabilizer in the production process, the defects of the lubricant base oil are overcome, the quality of the lubricant base oil is improved, and thus the product has the advantages of being stable in aging resistance and ultraviolet resistance, stable in color, pure in smell and the like.

Description

technical field [0001] The invention relates to a technology for improving the quality of lubricating oil base oil. Background technique [0002] In the refined decolorization production of lubricating base oils, there are generally factors such as relatively poor anti-oxidation stability, discoloration, odor and low transparency after a long time. Contents of the invention [0003] An object of the present invention is to propose a process for improving the quality of lubricating base oils. [0004] A process for improving the quality of lubricating base oil according to an embodiment of the present invention comprises the following steps: adding the refined oil into a clay pot, and raising the temperature to 90° C. to 100° C., adding clay and stirring for 25 minutes to 35 minutes, and then mixing the After the refined oil passes through the degassing tower, raise the temperature of the refined oil to 115°C-125°C, add a stabilizer with a mass fraction of 3‰-5‰ to the ref...
