he aim of the study was to investigate the ability of stretched exponential
kinetic equation to describe the sorption kinetics and expansion rate
of solid coal sample. In order to address this issue the sorption kinetics
of methane and carbon dioxide on bituminous coal was studied. At the
same time, the changes occurring in the sample’s overall dimensions,
which accompanied sorption processes was monitored. Experiments were
carried out at high pressure by means of the volumetric method on cuboid
solid samples. Stretched exponential equation (SE) modeling approach and
equation is proposed to fit the kinetic curves of gas deposition, as well as the
adequate kinetics of coal swelling. Compared to the other models described in
the literature, stretched exponential equation seems to give the best fit to the
experimental data. For the experiment, specially designed equipment was used,
enabling parallel measurements of sorption and dylatometric characteristics
of coal samples. Sorption capacity is measured by the manometric method.
The device is placed in a water thermostat. Methane of known volume and
pressure is decompressed and subsequently flows from the reference cell to
the sample cell, containing the coal sample. Strains in cuboid-shaped coal
samples are measured with a strain gauge. Linear deformations are controlled
by an electric resistant wire combined with a resistance transducer.
