| Abstract: | The adsorption potential theory was applied to coal/CH4 adsorption systems, the acquisition methods of adsorption characteristic curve was introduced. Based on the measured isotherm data under diferent temperature on the coal, the adsorption characteristic curve of 40℃ was acquired and its mathematics expression was established, then the isothermal adsorption curve of 30℃ and 50℃ were predicted. The result shows that the Mean Relative Percent Error is only 1.72% and 0.92%, the effect of this prediction is good. |
