Characteristics and Origin of Methane Adsorption Capacity of Marine, Transitional, and Lacustrine Shales in Sichuan Basin, China

Figure 12

Effect of pressure and temperature on methane adsorption capacity. (a) As the pressure increases, the methane adsorption capacity gradually increases, and the increasing trend decreases after 5 MPa. (b) As the temperature increases, the methane adsorption capacity gradually decreases, and after 40°C, the increase rate decreases.
