As the rapid development of the domestic automobile industry has driven the rapid growth of the lubricant market, from the perspective of the product structure of the production plant, it mainly produces three oil series of internal combustion engine oil, hydraulic oil and gear oil, and its output accounts for the total output. This also reflects the current consumption structure of lubricants in China. From the quality point of view, although the proportion of medium and high-end lubricants in China has been steadily increasing in recent years, the proportion of medium and high-grade products in finished lubricants is basically, but the proportion is still far from that of developed countries. Demand forecast The lubricating oil market is closely related to the demand for oil in industries such as automobiles, machinery, and transportation. The entire machinery industry accounts for a quarter of the national industrial output value. The development and progress of the machinery industry is accelerating, requiring high-grade lubricants that meet the requirements of high mechanical load, long life, low fuel consumption, energy saving and environmental protection.
According to the development plan of the relevant department, combined with the investigation of the department’s oil equipment, the domestic demand for lubricants. The development of lubricants in China High-quality base oils are the basis for the production of high-end lubricants. The base oils are mainly vacuum wax oil, catalytic wax oil, hydrogenation tail oil and other widely used distillate oils. These distillate oils can be used as lubricating base oils, as well as high-quality catalytic feeds, reforming materials and ethylene raw materials. . Most domestic lubricants are produced in large refineries, and their base oil supply is optimized to provide the most reasonable fractions after optimizing the crude oil processing process. However, a considerable number of lubricant manufacturers rely on outsourced base oil production. Because refineries will not specifically optimize the process for them, it is difficult for such lubricant plants to purchase high-quality base oil raw materials. This is also China’s low-grade lubricants. One of the main reasons at present.
Crude oil is a low-pour-point naphthenic crude oil with low sulfur and low wax content. The lubricating oil produced has a low viscosity index. It has the characteristics of heavy distillate, high density, high viscosity, low freezing point, etc. It is the best raw material for the production of some special lubricants. The low freezing point naphthenic lubricants produced with it can be used as electrical oils and refrigeration oils. , Rubber industry oil, cylinder oil and lubricating grease, etc. The lubricating base oil of crude oil not only has a higher yield than paraffin-based base oil, but also has a shorter process, resulting in lower production costs than paraffin-based base oils. The raw material of lubricating oil base oil produced by crude oil is not only of good quality, but also of low cost, which has strong market competitiveness. China's oil resources are becoming increasingly scarce. How to use resources reasonably and effectively based on the quality of China's crude oil is a problem worthy of study and optimization.
