The Guizhou Meijin Liuzhi coal-coke-hydrogen integrated utilization demonstration project is progressing smoothly. To date, approximately 4 billion yuan has been invested in this project; the first batch of coke ovens was successfully commissioned in December last year, and the project is expected to go into operation next month. It is understood that the Guizhou Meijin Liuzhi coal-coke-hydrogen integrated utilization demonstration project has a total investment of around 10 billion yuan, and it is a major project in Guizhou Province. The project comprises 8 sub-projects, including 3.8 million tons per year of high-quality metallurgical coke and 100,000 tons per year for carbon capture, utilization, and storage. It employs advanced international clean production technologies for large-scale coke ovens; the coke oven gas generated is separated and purified through new environmental-friendly processes, enabling the production of 40 million standard cubic meters of high-purity hydrogen per year. This approach helps to reduce carbon dioxide emissions by nearly 50,000 tons per year, achieving near-zero emissions. It is reported that during the coking process, this project efficiently recovers the waste heat from coke to generate high-temperature and high-pressure steam, which is then used by steam turbine generators to produce electricity, thus forming a coal-coke-electricity industrial chain ； By utilizing technologies such as hydrogen production, storage, and utilization, coke oven gas is subjected to advanced processing to produce high-purity hydrogen, which serves as the hydrogen fuel required for new energy vehicles, thereby establishing a coal-coke-hydrogen industrial chain ； Synthetic ammonia is obtained from coke oven gas through separation, transformation, and synthesis, to produce compound fertilizers required for crop growth, thus forming a coal-coke-chemicals industry chain. Upon completion, the project will play a significant role in facilitating the transformation of the traditional coal coking industry in Liuzhi Special Zone into a new type of coal chemical industry. It will also stimulate the development of related industries such as coal power generation, transportation and freight logistics, railway logistics, equipment manufacturing, new materials, and new energy.
