Influence of supercritical CO2-H2O fluid on nanopore structure of coal based on small angle X-ray scattering

The change in nanopore structure of coal with the presence of water due to supercritical CO2 (SCCO2) exposure could significantly affects CO2 storage in target coal seams. Thus, the interaction of SCCO2-H2O mixture fluid with long flame coal, gas coal and anthracite was simulated on a fluid geo-reac...
