It can be seen from Figure 3 that under the same pressure condition, with the increase in temperature, the gas adsorption capacity of coking coal shows a downward trend. This is because the adsorption of coal to gas belongs to physical adsorption, and adsorption is an exothermic process (Wang et al., 2012).So, with the rise in temperature, the gas molecules move more violently, and the time ...
