Study of hydrogen production from coal gasification in supercritical water

The coal supercritical water gasification technology is a new technology that directly converts coal into hydrogen, with advantages such as cleanliness, high efficiency, and low cost. With the global trend towards hydrogen energy development, the coal supercritical water gasification technology has broad application prospects. Research on this technology is significant for providing a new path for China's clean energy development, promoting sustainable development in the energy field, and contributing to global emission reduction and climate change response. This article analyzes the current development status of coal gasification technology, summarizes the related categories in four aspects: raw material selection, catalysts, reactors, and heating methods, and analyzes the unique advantages of each method. Based on this, a relatively efficient hydrogen production scheme is briefly selected. In addition, the future development trend of this technology is discussed. This article may provide a reference for clean energy development and the efficient utilization of coal resources.
