The effect and prediction of temperature on adsorption capability of coal/CH4
Based on adsorption isotherm experiment on two coal samples under different temperatures using the HCA adsorption parameters determinator, the effect of temperature on adsorption capability of coal/CH4 was analyzed. The prediction of adsorption capability of coal/CH4 of 20℃, 40 ℃, 50 ℃, 60 ℃ were done using the adsorption characteristic curves of 30℃ by adsorption potential theory, and compared with the experimental date. The results show that, in the research temperature and pressure range, the adsorption amount and saturated adsorption amount a decrease as the adsorption temperature increases, relation between saturated adsorption amount a and temperature can be described by an exponential function, the variation of adsorption constant b is non-monotonic. It is concluded that there is no relationship between the adsorption characteristic curve and temperature of coal/CH4 adsorption system. The relative error in saturated adsorption amount a prediction is 1.23％~3.80％, the relative error in adsorption constant b prediction is 1.09％~5.26％, and the prediction effect is better.
