This thesis discusses an experimental study involving sorption studies using methane, carbon dioxide, and a multicomponent gas mixture representative of in situ gas composition. Using the isotherms for pure methane and carbon dioxide, isotherm and variation in gas composition with desorption for gas mixture were established using a numerical technique. When using gas mixture, composition of the desorbing gas at each pressure level was monitored. Results indicate that during desorption, methane concentration decreased as the pressure was decreased while carbon dioxide concentration increased. Experimental results for sorption and variation in gas composition of the gas mixture compare very well with the theoretically obtained results. It is, therefore, possible to establish the sorption isotherm, Langmuir constants for gas mixtures and estimate the variation in gas composition with desorption theoretically, if the sorption isotherms for individual component gases are available and the in situ gas composition is known.Type
