“…Sorption isotherms of CO2 and CH4 measured up to 3.4 MPa were used for evaluation of the computed set of isotherms. The MSM model was described in previous articles [12][13][14]. The results that were obtained are presented on Figures and Tables 2 and 3.…”

Abstract. The aim of the study is to estimate the theoretical capacity of coal deposits in terms of carbon dioxide storage and methane recovery estimate during the injection of carbon dioxide. The Multiple Sorption Model was used for this purpose. The range of sorption measurement data on which the simulations were based does not exceed the critical point for both methane and carbon dioxide. The model allows to calculate absorption, adsorption, expansion and total theoretical sorption. For further consideration absorption was used as the process of the percolation of the gas in the bulk of the coal matter as well as the total theoretical sorption, the occurrence of which is possible due to the presence of fractures in the coal seam. Calculated levels of absorption and the total theoretical adsorption were applied to estimate the possible storage capacity of carbon dioxide based on the data associated with the content of coal in the mining fields of individual Polish coal mines. Moreover, MSM development for the gas mixture sorption can be used to roughly assess the recovery of methane naturally occurring in coal deposits during such a process.

“…Thus, in order to get valuable information on particular sorption system it is necessary to complete the procedure by reliable assessment of the resultant model's parameters. So far, information gained on the coal structure and sorption system was evaluated verifying general agreement of the results with the database of optimization experiments, coming from our earlier works (Jodłowski et al 2013). Therefore, one may expect that team's works should be focused on enhancement of the evaluations reliability, to reduce uncertainty and improve the quality of the estimates.…”

“…Ecological issues and prospective economic aspects have resulted in increasing interest in the sequestration of carbon dioxide and the enhanced coal bed methane recovery (ECBM) process, that is, recovery of methane from carboniferous deposits with simultaneous CO 2 sequestration (Dutka et al 2013;Jodłowski et al 2007;Jodłowski 2008;Kaszuba and Janecky 2013;Wdowin et al 2014a, b). This constitutes one method to lower the emission of carbon dioxide.…”

Kinetic models assessment for swelling of coal induced by methane and carbon dioxide sorption

The ability of five kinetic equations to describe the sorption kinetics and expansion rate of solid coal samples was investigated. The conducted experiment included the measurements of sorption of methane and carbon dioxide on cuboidal hard coal samples at high pressure using volumetric method. Simultaneously the kinetics of coal sorption induced swelling was monitored. All of the approaches used to fit the experimental sorption and dilatometric data were literature-based equations. Two equations represent the traditional approach for sorption on powder and grain fractions based on the bidisperse gas transport model, and have been used to interpret and quantify the observed gas uptake rates in coal. The other three kinetic equations are the pseudo-second-order kinetic equation, Elovich equation, and stretched exponential (SE) equation. Four of the five equations are suitable to describe the kinetics of methane and carbon dioxide sorption in the porous structure of solid coal samples and the kinetics of coal expansion that accompany the sorption processes. The SE equation gave the best fit to the experimental data.
