Description
Technical Field
The invention belongs to the field of preparation methods of degradable low-carbon lubricating oil, and particularly relates to a preparation method of degradable low-carbon lubricating oil
Background
Low carbon economy has recently received much attention in china. China is a world-polluted big country, and European Union and the United states threaten to open up 'carbon customs duty', which is undoubtedly disadvantageous to China exported to the big country in the world. The content of sulfur and phosphorus components in the lubricating oil directly determines the content of carbon discharged. Because sulfur dioxide generated by using lubricating oil has obvious synergistic effect on greenhouse gas emission reduction, the lubricating oil industry is a major household of carbon emission practically all the time. According to measurement and calculation, the benefit coefficient of sulfur dioxide and carbon dioxide is 1: 38, namely, the emission reduction of 38 ten thousand tons of carbon dioxide is driven every 1 ten thousand tons of sulfur dioxide is reduced. While the domestic automotive lubricating oil mainly takes SG and CF-4 grades as main grades, and the sulfur and phosphorus content of the domestic automotive lubricating oil is 3 to 8 times higher than that of the domestic automotive lubricating oil in developed countries. It is conceivable that the direct and indirect carbon emissions produced by the lubricating oil industry are a significant figure each year.
At present, most of the most popular lubricating oil products in the market of China are lubricating oil taking petroleum as base oil, are difficult to degrade and are left in the environment for a long time. The annual global consumption of the lubricating oil is 3600-.
Vegetable oil-based lubricating oils are environmentally friendly lubricating oils such as soybean oil, corn oil, rapeseed oil, cottonseed oil, etc., of which the first to enter the market is the lubricating oil synthesized from rapeseed oil (oil content 35-40) in germany. However, rapeseed oil has a high condensation point, is easy to solidify at low temperature, and has poor low-temperature performance after esterification. Rapeseed oil has poor oxidation stability and is easy to form oil sludge and precipitate at high temperature.
Therefore, it is necessary to develop a degradable lubricating oil and a preparation method thereof.
