Problems solved by technology

[0004] The existing damping oil generally adopts naphthenic oil, but naphthenic oil is extracted from naphthenic crude oil, and naphthenic crude oil has few resources in petroleum products, and its reserves only account for the world's proven reserves. 2.2% of oil reserves are scarce resources, which makes the exploitation cost of naphthenic crude oil higher and higher, which in turn makes the cost of naphthenic oil higher and higher

Abstract

The invention discloses white oil used as shock absorber oil and a preparation method thereof. The preparation method of the white oil used as the shock absorber oil comprises the following steps: S1,adding #68 basic oil and #100 basic oil into a reaction container according to a ratio of 1:2, performing heating to 120-130 DEG C, further adding a metal catalyst, and keeping the temperature for 10-15 minutes; S2, increasing the temperature to 200-220 DEG C, adding an accelerant, and introducing hydrogen at pressure of 50-55MPa; S3, performing a reaction for 15-20 minutes, performing centrifugal treatment on the mixture in the reaction container, and removing filter residues so as to obtain pretreatment oil; S4, mixing the pretreatment oil with #46 basic oil of a mass identical to that of the #100 basic oil, increasing the temperature to 250-260 DEG C, adding a catalyst, and introducing hydrogen at pressure of 58-60MPa; and S5, performing a reaction for 10-15 minutes, performing centrifugal treatment on the mixture in the reaction container, and removing filter residues, so as to obtain the white oil used as the shock absorber oil. The white oil prepared by using the method has theadvantages of being capable of completely replacing naphthenic oil to be used as the shock absorber oil and beneficial to cost reduction.

Description

technical field [0001] The invention relates to the petroleum field, more specifically, it relates to a white oil which can be used as shock absorber oil and a preparation method thereof. Background technique [0002] White oil, also known as paraffin oil, white oil, mineral oil, usually refers to crude oil (or oil) that has been mined and processed. [0003] Shock absorber oil is a liquid that is injected into the shock absorbers of airplanes, tanks, cars, etc. to reduce their ups and downs. Shock absorbing oil must be stable in nature, free of impurities and moisture, and should have appropriate viscosity and good low-temperature fluidity. [0004] The existing damping oil generally adopts naphthenic oil, but naphthenic oil is extracted from naphthenic crude oil, and naphthenic crude oil has few resources in petroleum products, and its reserves only account for the world's proven reserves. 2.2% of the oil reserves is a scarce resource, which makes the exploitation cost o...
