Extraction of coal using supercritical water

WebJul 8, 2002 · In this work, we examine the potential of supercritical water (SCW)–phenol mixtures as extraction solvents for coal liquefaction. For this type of process, no hydrogen is used in the liquefaction. Water becomes supercritical fluid, when the temperature and pressure are increased above its critical point ( Tc: 647 K, Pc: 22.1 MPa). WebApr 13, 2024 · CO2 geological storage (CGS) is considered to be an important technology for achieving carbon peak and carbon neutralization goals. Injecting CO2 into deep unminable coal seams can achieve both CGS and enhance coalbed methane (ECBM) production. Therefore, the deep unminable coal seams are considered as promising …
