“…Thus, "desorption" means a number of processes resulting in the release of the sorbing gas from the sorbent. When speaking about the release of methane from a coal bed into an excavation, we typically mean the combination of the filtration (Crank 1975;Timofejew 1967;Pillalamarry et al 2011;Hu et al 2009;Wu et al 1998), diffusion, and sorption processes, which will further be referred to as "the sorption proper" (Harpalani and Chen 1997;Pillalamarry et al 2011;Day and Sakurovs 2008;Weniger et al 2010;CeglarskaStefańska and Zarębska 2005;Majewska et al 2009;Busch and Gensterblum 2011;Nagaoka and Imae 2003). Under laboratory conditions, in which case the investigations are carried out for small-sized grain samples, we can assume that the transportation of gas is influenced mainly by the diffusion processes.…”

Traditionally, physicochemical processes whose result is the release of methane from a coal sample-often referred to as desorption-are discussed in relation to two phenomena, i.e., the transportation of gas inward (or outward) the porous substance, and the desorption (or sorption) proper of gas from the coal surface. The complex pore structure of coal necessitated the adoption of an arbitrary division of the gas transportation into: the diffusion of gas within the pore network in grains (understood as a molecular phenomenon) and the filtration of gas through the system of fissures and large pores (understood as a phenomenon related to the fluid mechanics). The filtration-type transportation of gas through a porous medium is most typically discussed in the context of the flow of gas through coal beds, or other porous rocks. In laboratory analyses carried out on granular samples obtained from the porous material, the filtrational flow of gas among the sorbent grains and within the fissure system is so fast (as compared to the diffusion occurring inside the grains) that the decisive factor influencing the kinetics of gas release is, most often, diffusion. In the case of such observations, it is assumed that the process of the sorption proper is almost instantaneous in its nature. There are no theoretical premises that would challenge an assumption thus formed, however, it would be very interesting to carry out an experiment confirming their existence. The present paper discusses an attempt to estimate, under laboratory conditions, the kinetics of the sorption proper. It provides a description of the specially built measuring equipment, as well as the results of the performed experiments, together with their analysis. In the performed experiments, the obtained time constants of sorption were smaller than 50 ms. The lowest values did not exceed 10 ms. Since the obtained time constant values are very low-in spite of the fact that it was impossible to completely eliminate the delays connected with the transportation of molecules to the sorption sites-the authors are of the opinion that the process of sorption proper shall be assumed to be instantaneous.
