1. The application of biotechnology in lubricating oil (fat)
At present, most of the world's energy and organic chemical raw materials come from petroleum, coal and natural gas. They have made great contributions to social progress and development. However, in the long run, it is not an ideal resource that humans can rely on for a long time. The resources and energy that humans can rely on for a long time in the future should be rich in reserves, renewable, and free of pollution to the environment. Therefore, the participating experts generally believe that plant-based biological resources will be the ideal choice for the future of mankind. For China, the development of biodiesel has the following significance: Biodiesel is an ultra-clean diesel that protects the environment from atmospheric pollution, and it also has the characteristics of reducing CO2 emissions and reducing the greenhouse effect. Developing biodiesel is beneficial to increasing diesel production and improving China's oil structure. The ratio of diesel to steam; the production of biodiesel compared with the refining of clean petroleum and diesel, the process is short, the investment is saved, the processing cost is low; while the production of biodiesel, the by-product of high value-added glycerol; from the production of biodiesel from soybean oil, also Can be comprehensively used to make biodegradable lubricating oils, cleaning solvents, industrial solvents, etc. At the same time, the development of biodiesel can adjust the structure of agricultural products, open up a new road for agricultural development, and increase farmers' income. At present and in the future, China still needs a lot of oil imports, and the use of vegetable oil for diesel production also opens up a way to protect China’s energy security.
The application of biotechnology in lubricants (fat) Biotechnology used in research and development of degradable lubricants (fat) began in the 1970s. Green chemistry will make the development of biodegradable lubricants (fat) even faster in the 21st century.
At present, biodegradable lubricating oil (fat) research fields include: biodegradable hydraulic oil, general-purpose biodegradable grease, and biodegradable lubricating oil.
Mainly used for biodegradation of lubricating oil (fat) are vegetable oils and synthetic lipids. At present, rapeseed oil and sunflower seed oil are used more often for vegetable oils, and polyol esters and complex fats for synthesizing fats such as alcohols and fatty acids.
The degradable lubricating oil (fat) is non-toxic, has good lubricity and viscosity-temperature performance, and has a high viscosity index and is easily degraded to generate carbon dioxide and water.
Europe, the United States, and Japan have carried out research on the biodegradation of lubricating oils (fat). Some famous manufacturers have successively developed biodegradable lubricating oils (fat), and they have evaluation methods for biodegradability.
In Europe, biodegradable lubricants have accounted for about 7%. Some countries in Northern Europe have also enacted regulations to restrict the use of certain mineral lubricants to promote the use of biodegradable lubricants (fat).
Many domestic companies have also conducted biodegradation of lubricating oil (fat) research. Shanghai Jiaotong University for the purpose of developing biodegradable lubricating oils, modified the base oil of green lubricants and studied the oxidation mechanism, screened some antioxidant additives with good effect, and synthesized several series of extreme pressure Anti-wear additives and their tribological properties were investigated to obtain good results. Biotechnology has a broad application prospect in the field of lubrication.
2. Application of Nanomaterials and Technology in Lubricants
Friction and wear are ubiquitous natural phenomena. Friction loses about one-third of the world's primary energy. Wear is one of the three main forms of damage and failure of materials and equipment. Lubrication is the most effective technology for reducing friction, reducing or avoiding wear. The development of lubricants with good anti-wear properties, high load-bearing capacity, a certain repair function for worn surfaces, and no pollution or less pollution to the environment is one of the important topics in chemistry, materials science and tribology.
In recent years, nanomaterials have been rapidly developed, and the application of nanomaterials and technologies in the field of lubrication has been highly valued by tribological science and technology workers. Many research institutes and universities have successively applied nanomaterials to lubricating oils (lipoids) to improve their anti-wear and extreme-pressure properties.
The Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences used chemical surface modification to prepare nanoparticles, and studied the mechanism of anti-friction, anti-wear and lubrication of nanoparticles in lubricating oils. Studies have shown that nanoparticles as a lubricant (fat) additive has a certain repair function, and reduce the cost of organic modified nanoparticles, to achieve its large-scale production, is the basis for the successful application of nanomaterials in lubricants (fat).
in conclusion
In the new century, China's lubricant industry faces both severe challenges and good development opportunities. The fierce competition will make China's lubricant market full of vitality. From the perspective of development status, the standards for gear oil and hydraulic oil in China's national lubricants and industry standards have reached the international advanced level, and at the same time, they can also establish gantry performance assessment projects that are equivalent to the international advanced level requirements. In the aspect of internal combustion engine oil specifications, due to the rapid replacement of internal combustion engine oils in the world, the national and industrial standards for internal combustion engines in China are very different from those in foreign countries. For every new grade quality specification proposed by the US API, there is a corresponding and new gantry assessment method. The stipulated standards and gantry assessment are developed simultaneously. There are various types of vehicles imported from China, such as Europe, the United States, and Japan, and the standards they implement are not the same. Therefore, according to the characteristics of China's domestic and joint-venture automotive engines, the requirements for performance evaluation of lubricating oil pedestals should be established, and the specific conditions for China should be introduced. The lubricating oil specifications have made China's internal combustion engine oil standards upgrade with new requirements for environmental protection laws and engine fuel economy. The total demand for lubricants in China will increase steadily, and high-grade lubricants will grow at a faster rate. In vehicle lubricants, the proportion of diesel engine oil will gradually increase due to the development of diesel vehicles. With the continuous increase of engine power, fuel economy will promote the continuous upgrading of lubricating oil, and environmentally friendly requirements will promote the lubricating oil to be cleaner.
In short, the future of lubricants will face many serious challenges. In line with the world trend, energy saving, low emissions, no pollution, and long life will become the direction of China's lubricants.
