The researchers studied how temperature affects the amount of coalbed methane that can be absorbed. They collected coal samples from different mines and conducted experiments at various temperatures. The results showed that the adsorption capacity of dry coal samples was higher than that of wet samples at the same temperature. They also found that the temperature and adsorption capacity had a linear relationship during the adsorption and desorption processes. This information can help predict the amount of coalbed methane in deep areas and determine the radius for collecting gas in production wells.
