The adsorption difference of water and methane by long-flame coal is compared and analyzed by molecular simulation. The results show that when the single-component isothermal adsorption pressure is less than 15 MPa, the adsorption capacity of CH 4 and H 2 O increases gradually with the increase of the adsorption pressure, and the average adsorption amount of H 2 O is much higher than that of CH 4 ; after more than 15 MPa, the average adsorption amount of CH 4 and H 2 O is saturated. When the two-component isothermal adsorption pressure is less than 0.7595 MPa, the long-flame coal molecule can adsorb both CH 4 and H 2 O; after more than 0.7595 MPa, the average adsorption amount of H 2 O is much larger than that of CH 4 indicating that H 2 O is in a dominant position in the competitive adsorption with CH 4 .
