【Major Chemical Equipment Innovations】By 2022, the second-generation coal direct liquefaction technology with a capacity of 2 million tons per year per series had passed the acceptance tests
Thread Content
On August 31, news came from **Energy Group** stating that the second-generation coal direct liquefaction technology developed independently by the group’s chemical company has passed the evaluation of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation. The evaluation committee unanimously agreed that this achievement is highly innovative, possesses independent intellectual property rights, and its overall technology is at the international leading level. The evaluation committee is composed of Academician Cao Xianghong from Sinopec, Academician Xie Kechang from the Chinese Academy of Engineering, Academician Hu Yongkang from Dalian Research Institute of Petrochemical Technology, as well as 9 renowned experts in the field of energy and chemical engineering from institutions such as East China University of Science and Technology and China National Coal Group. The evaluation committee believes that, based on these results, an industrial-scale coal direct liquefaction plant with a capacity of 2 million tons per year can be designed and constructed, and recommends accelerating its industrial application. It is reported that by implementing this technology, the production capacity of a single series in these projects is expected to increase to 20 million tons per year. This will **reduce the investment and operating costs of coal-to-oil projects, improve energy utilization efficiency, and facilitate a shift from producing mere fuels to manufacturing coal-based specialty fuels, high-end carbon materials, and chemicals with high added value. It will also help expand the coal-to-oil industry chain and enhance economic benefits, thereby promoting the high-quality development of this industry.
Since the 1990s, the contradiction between the shortage of oil and gas resources and rising demand in our country has become increasingly prominent. Shouldering the strategic mission of achieving clean and efficient conversion and utilization of coal to ensure **energy security, in June 2003, the pioneers of coal chemical engineering at **Energy Group chose to pursue the path of Chinese innovation. After thousands of tests using small-scale and pilot-scale facilities, they succeeded in developing the core technology for direct coal liquefaction into oil in 2004, thus officially launching the industrialization process. Subsequently, they successively overcame the manufacturing challenges of multiple ultra-large specialized equipment units, including coal direct liquefaction reactors, hydrogenation stabilization reactors, and dry coal powder gasifiers. On December 31, 2008, the pilot project for direct coal liquefaction was successfully tested for the first time, making China the only country in the world to possess the key technologies for direct coal liquefaction on a million-ton scale. Since the world’s first million-ton-scale demonstration plant for direct coal liquefaction was built and put into operation, **Energy Group Chemical Company has been committed to improving the economic viability and competitiveness of direct coal liquefaction technology, carrying out relentless research efforts in this area. They have successfully developed second-generation coal direct liquefaction technologies, such as new types of efficient reactors and reaction systems, new processes for the preparation of catalysts for coal direct liquefaction, flexible control of efficient hydrogen supply solvents, oil residue extraction coupled with vacuum distillation, and solid-liquid separation. Industry experts believe that the successful evaluation of the second-generation coal direct liquefaction technology represents another milestone in the development of this technology. It further strengthens China’s technical position in the global field of coal-to-chemicals production, and will accelerate the technological advancement of coal direct liquefaction in China. The successful development of the second-generation coal direct liquefaction technology can provide solid support for the clean and efficient utilization of coal as well as for the establishment of strategic bases for coal-to-oil and gas production.
The core technology for direct coal liquefaction to produce oil is truly amazing; thank you very much to the original poster for sharing this information
