The impact of components concentration on CH4 desorption in CO2-CH4 mized gas desorption isotherm ezperiments
(0) In order to discuss the impact of gas components concentration on CH4 desorption, the CO2CH4 mixed-gas with different components concentration adsorption/desorption isotherm experiments were carried out, the variation regularity of gas component concentration and the adsorptive volume in the desorption process were analyzed. The results indicated, in the process of CO2-CH4 mixed-gas desorption isotherm experiments, the desorption rate of CO2 is lower and that of CH4 is higher. The desorption rate of CH4 and the adsorption rate of CO2 at unit pressure drop increase along with the relative concentration of CO2 component. The higher CO2 component concentration, the more advantageous to the desorption of CH and the adsorption of COz on coal, and the more obvious displacement effect of CO2 to CH4.
