preparation example Construction

[0032] The present invention also provides a preparation method of the above-mentioned gas-to-oil synthetic compressor oil composition, which includes the following steps: adding ester base oil into a blending kettle with a stirrer, heating to 60-70°C; For other components except oil, adjust at 80-90°C for 2-4 hours until the mixture is uniform and transparent; finally add gas oil and adjust for 0.5-1 hour until uniform.

[0033] The technical scheme of concrete implementation of the present invention comprises:

Embodiment 1

[0035] A gas-to-oil synthetic compressor oil composition, its components are distributed as follows by weight percentage:

[0036] Gas oil: 90.4%, ester base oil: 5%, antioxidant: 4%, sulfur or phosphorus extreme pressure antiwear agent: 0.08%, rust inhibitor: 0.25%, metal passivator: 0.25% , anti-emulsifier: 0.02%; wherein, the gas-to-oil is a base oil produced based on Fischer-Tropsch synthesis technology, and its main component is isomerized linear alkanes. The main test properties of the synthetic non-staining hydraulic lubricant obtained in Example 1 are shown in Table 1.

Embodiment 2

[0038] A gas-to-oil synthetic compressor oil composition, its components are distributed as follows by weight percentage:

[0039] Gas oil: 70%, ester base oil: 27.5%, antioxidant: 2%, extreme pressure antiwear agent containing sulfur or phosphorus: 0.04%, antirust agent: 0.2%, metal passivator: 0.2% , anti-emulsifier: 0.06%; wherein, the gas-to-oil is a base oil produced based on Fischer-Tropsch synthesis technology, and its main component is isomerized linear alkanes. The main test properties of the synthetic non-staining hydraulic lubricant obtained in Example 2 are shown in Table 1.

Abstract

The invention discloses a gas-to-oil synthetic compressor oil composition which comprises the following components in percentage by weight: 70%-95% of gas-to-oil, 5%-30% of ester base oil, 0.5%-8% of an antioxidant, 0.01%-1% of a sulfur-containing or phosphorus-containing anti-wear reagent at extreme pressure, 0.01%-1% of an anti-rust agent, 0.001%-0.5% of a metal deactivator and 0.001%-0.1% of a demulsifying agent, wherein the gas-to-oil is base oil produced based on a Fischer-Tropsch synthesis technology, and the main component of the gas-to-oil is isomeric straight-chain alkane. The gas-to-oil synthetic compressor oil composition provided by the invention has excellent oxidation stability, thermal stability, low-temperature fluidity and other properties, and is especially suitable for lubrication of large, high-temperature and high-pressure screw compressors; the gas-to-oil synthetic compressor oil composition provided by the invention has longer service life, is biodegradable, and is beneficial to ecological environment.

Description

technical field [0001] The invention relates to a gas-to-oil synthetic compressor oil composition, in particular to a gas-to-oil synthetic compressor oil composition for lubricating screw air compressors. Background technique [0002] The rapid economic growth has increased the demand for oil in my country, and my country has become the second largest oil consumer in the world. However, oil resources are becoming increasingly scarce, environmental regulations are becoming more and more stringent, and the proven recoverable reserves of natural gas continue to increase. It is of great significance to develop natural gas-to-liquids (GTL) technology and to promote the application of GTL. [0003] The method of converting natural gas synthesis gas (a mixture of CO and H2) into liquid hydrocarbons through catalyst action is called Gas to Liquid (GTL), invented by German scientists Frans Fischer and Hans Tropsch in 1923, referred to as Fischer-Tropsch FT synthesis.
