摘要
Objective The technical development of COstorage and enhanced coalbed methane(CO-ECMB) recovery requires reliable and detailed information on gas adsorption. In most cases of geo-storage COis injected in the supercritical state(Tc=31.1 °C, Pc=7.38 MPa). In the supercritical state, the fluid of supercritical CO(Sc-CO) can not only react with minerals under the condition of water, but also extract small organic molecules from coal
