On November 3, the **Science and Technology Awards Ceremony was held in Beijing. The project titled “Innovative Development and Industrialization of a Complete Set of Technologies for Indirect Coal Liquefaction with an Annual Capacity of 4 million tons,” which was completed through collaborative efforts by **Energy Group’s Ningxia Coal Industry Company and more than 20 other organizations, was awarded the first prize in the **Science and Technology Progress Award category. It is understood that through innovative research and collaborative efforts, this project overcame the key core technologies that posed challenges in large-scale indirect coal liquefaction. It achieved scale-up from pilot-scale operations of a few thousand tons to a capacity of 4 million tons per year. Significant innovations were made in areas such as the basic theories of indirect coal liquefaction, key technologies, major equipment and materials, scale-up and system integration techniques, as well as energy and water conservation. A set of replicable and scalable technologies for indirect coal liquefaction was developed, and the world’s largest single-unit indirect coal liquefaction facility with a capacity of 4 million tons per year was built. This facility operates in a safe, stable, and clean manner, and its overall technical level is among the best in the world.
In particular, the project introduced a high-temperature slurry-bed Fischer-Tropsch synthesis process, achieving high yields of oil products and high energy utilization efficiency in coal indirect liquefaction, reaching international leading levels； The developed high-efficiency slurry-bed Fischer-Tropsch synthesis reactor enabled the engineering scale-up of high-temperature slurry-bed Fischer-Tropsch synthesis ； Breakthroughs in the development of key technologies for major equipment such as single-nozzle dry coal powder pressurized gasification furnaces and highly pure hydrogen-resistant ultra-thick steel plates, as well as for critical materials, have enabled the domestic production of major equipment and materials used in coal indirect liquefaction on a million-ton scale. This has filled multiple gaps in China’s capabilities and broken foreign technological monopolies ； The development of integrated systems and comprehensive technologies for the clean operation of large-scale coal indirect liquefaction plants has enabled the safe, stable, and clean operation of the world’s largest single-unit coal indirect liquefaction facility with a capacity of 4 million tons per year. It has been determined that \"the overall technology of this project is at the international leading level.\"
