The aim of the study was to analyse the effect of temperature on the sorption and diffusion of
CO 2 and CH 4 on hard coal. Four coal samples, characterized by various degrees of …

In the conducted research, the effect of moisture on CO 2 sorption and transport processes
and changes occurring in the coal pore structure were investigated in detail. The …

Among the numerous factors that have an impact on coal permeability, coal porosity is one
of the main parameters. A change in the mechanical stress applied to coal results in a …

The aim of this research was to compare the structure, sorption properties and the kinetics of
sorption to CO 2 and CH 4 in nanomaterials with a very orderly structure and in structurally …

The present paper discusses the concept of measuring the process of sorption by means of
the volumetric method, developed in such a way as to allow measurements performed under …

Low-pressure sorption tests were carried out on samples of selected Polish bituminous coal
in coal–methane and coal–carbon dioxide systems. The purpose was to determine the …

In the present paper, the authors discussed the functioning of their own analyzer for
measuring gas contained in the pore space of high strength rocks. A sample is placed inside …

The present paper discusses the idea of an innovative device for sorption measurements,
working under isobaric conditions and based on a precise piston pressure regulator. As part …

The content of natural methane in hard coal seams, called methane-bearing capacity, is the
basic parameter that enables the level of methane hazard to be determined in hard coal …

The article discusses the validation process of a certain method of balancing gas contained
in the pore space of rocks. The validation was based upon juxtaposition of the examination …
