Efficient coal-based power generation via optimized supercritical water gasification with chemical recuperation

Experimental Investigation of the Effects of Inorganic Components on the Supercritical Water Gasification of Semi-Coke

“…Taking a 1000 MW scale power generation unit as an example, the SCWG-based coal consumption rate can be reduced to 244.8 g/kW•h, and the power generation efficiency can reach 56.7%, which is significantly better than traditional coalfired power generation [9]. The SCWG technology of coal is a breakthrough in the clean utilization of coal, and the research and industrial application of this promising technology are consistent with global sustainable development initiatives such as the United Nations' Sustainable Development Goals [16].…”

“…This enables SCW to achieve low mass resistance, high solubility of produced gases, easy separation of salts and impurities, and high reaction rate when used as a gasification medium [9,10]. In recent years, the supercritical water gasification (SCWG) of coal, a novel coal gasification technology, has received extensive attention and in-depth research due to its clean, efficient, and low-cost characteristics [11][12][13][14][15][16][17]. In the SCWG of coal, elements such as C, H, and O will be converted into gas-phase products, mainly existing in the form of H 2 and CO 2 [18].…”
