Influence of dynamic supercritical CO2 on nanopore structure of coals based onlow-temperature nitrogen adsorption
The dynamic interaction of SCCO2 with coking coal and lean coal was simulated on a dynamic SCCO2 extraction system under conditions of temperature of 55 ℃ and pressure of 12 MPa. The low-temperature nitrogen adsorption was adopted to address the alterations in nanopore structure of coal samples, and...
