High-end Lubricant Developed by Ningxia Coal Industry Co., Ltd. Proven Satisfying in Tests

On November 24, the high-end lubricant base oil using Fischer-Tropsch wax, jointly developed by Ningxia Coal Industry Co., Ltd. (“Ningxia Coal” for short) under CHN Energy and research institutions including the National Institute of Clean-and-Low-Carbon Energy (NICE), was proven to meet relevant requirements in tests when it was used to produce mixed hydraulic oils and engine lubricating oils. It is expected to fill in the void of China’s homemade high-end lubricants.

Employees conducted a lubricant mixture test.

At present, China is highly reliant on exports in terms of high-end lubricants. To realize the goal of developing high value-added coal-to-liquid (CTL) downstream products, Ningxia Coal joined hands with NICE and other research institutions to launch the project for the R&D of high-end lubricants using Fischer-Tropsch wax in March 2020. By the end of December 2021, the project completed pilot trial and the development of technical kit with a capacity of 150,000 tons per year. This marked that Ningxia Coal has grasped the technology to produce high-end lubricant base oil with Fischer-Tropsch wax for which it owned independent intellectual property right. Compared to traditional petroleum base oil, this technology features advantages such as short workflow, simple operation, low cost, and outstanding quality of products.

So far, the hydraulic oil made with this technology has been put into trial use in the company’s internal chemical division’s coal pulverizer hydraulic systems for more than 4,000 hours. Besides, gasoline engine lubricants made with this technology have been used by external partners in driving tests totaling 12,000 kilometers, and diesel engine lubricants in driving tests totaling 34,000 kilometers as well as in internal underground mine diesel-fueled vehicles for trial use of 2,200 kilometers.
