This paper presents a study of the application of the properties of water vapor as a gas with high potential energy, strongly dependent on temperature and pressure. Analyses of water vapor sorption on two types of silica gels (SG) (90 wt.%) enriched with carbon nanotubes (CNTs) (10 wt.%), in the context of their application in the design of adsorpt...
Article
The effective sorption of methane with mesoporous adsorbents is one of the most sought-after methods of energy storage. The constant development of organometallic networks and the synthesis of new materials increases the efficiency of methane sorption, reaching new record amounts of gas adsorbed per gram of adsorbent. In this study, we present the...

The work presents the laboratory studies on permeability of two bituminous coal briquettes under confining pressure conditions. The research was carried out in order to assess the possibility of using bituminous coal as a sorbent for CO2 storage in underground seams. Coal permeability tests were carried out on an original apparatus for testing seep...
Article
Full-text available
The authors derived the analytical solution to diffusion equations. The solution requires linearization of diffusion equations, as well as developing the obtained expression into a series. In particular, the result of the first procedure is highly deviated from the exact solution. The authors conducted a sorption experiment and then, in relation to...

In recent years, the interest in the sorption properties of coal in conditions corresponding to in situ has increased due to the continuous development of research on CO2-ECBM (Enhanced Coal Bed Methane recovery) technology. In order to gain a better insight into a number of phenomena related to filtration, sorption and CO2/CH4 exchange sorption oc...
Article
The aim of the study was to analyse the effect of temperature on the sorption and diffusion of CO2 and CH4 on hard coal. Four coal samples, characterized by various degrees of coalification, were used in the research. The sorption measurements were carried out in three temperature values: 278 K, 313 K and 353 K and for the consecutive pressure valu...
Article
The aim of this research was to compare the structure, sorption properties and the kinetics of sorption to CO2 and CH4 in nanomaterials with a very orderly structure and in structurally heterogeneous coal. The authors tested synthetic materials such as multiwall carbon nanotubes (MWCNT) and reduced graphene oxide (rGO) as well as natural materials...
Article
Temperature is one of the main factors influencing the parameters describing the phenomena of sorption, diffusion and filtration of gases occurring in the pore space of coal. While the influence of temperature on sorption capacity and the diffusion coefficient of coal is known, changes in the coal permeability coefficient due to temperature changes...
Article
Full-text available
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 change of porosity. The main objective of the conducted research was to answer the following question: is a decline in coal permeability a direct effect of a decrease in coa...
Preprint
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 of rocks' porosity and the effects of comminution in terms of assessing the possibility of opening the pore space. The tests were carried out for six dolomite samples...
Article
Full-text available
From the perspective of economy and safety, balancing gas contained in the pore space of rocks is extremely essential, predominantly to establishments dealing with extraction of mineral resources. One of the main methods of evaluating the amount and composition of gas contained in the pore space of a rock is releasing the gas as a result of comminu...
Article
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 a hermetic measuring chamber, and then undergoes impact milling as a result of colliding with the vibrating blade of a knife which is rotationally driven by a high-speed br...
Article

The aim of this paper was to investigate the repeatability of sorption processes occurring in the coal-methane system during multiple measurement series. For research purposes, three granular samples of coal sorbent were used. The samples were subjected to a series of three measurements, each time performed under the same conditions. During each se...

The characteristics of copper-bearing rocks that include the structural and textural parameters are an important factor determining a possible gas accumulation in those rocks. In September 2009, in the Rudna copper mine in Poland, an outburst of gases and dolomite occurred. The analysis of the outburst mass showed that one of the main causes of the...

The unipore methane diffusion model based on the solution of the second Fick’s law describes effectively the kinetics of methane release from coal grains. The knowledge of the model describing the kinetics of methane release from coal, the coalbed methane content, the sorption isotherm, the effective diffusion coefficient and the coal particle size...

The authors of the present paper designed and constructed a prototype of an instrument which enables fully automated determination of the desorbable methane content and effective diffusion coefficient in underground conditions. Due to microprocessor analysis of the recorded data and the application of the mathematical model of the diffusion process...
Article
The necessity to reduce the increasing amounts of carbon dioxide (CO2) in the atmosphere entails searching for some effective methods that enable safe storage of the gas in question. A method known as enhanced coal bed methane recovery (ECBM), involving injection of CO2 into unexploited coal beds, makes it possible to obtain CH4, too. The ECBM meth...

The article presents findings of a study on CO2/CH4 exchange sorption taking place in a coal briquette, initiated by the injection of a CO2 into a briquette that was previously saturated with CH4. The briquette was subjected to multiple cycles consisting of vacuum outgassing, CH4 saturation under 10 bar pressure, and an exchange sorption process. I...

The paper presents the study of CO2/CH4 exchange sorption in a coal briquette. The briquette was formed inside a heavy-walled steel pipe that served the purpose of a measuring chamber. The briquette with a porosity of 8.3%, a diameter of 0.096 m and a length of 0.280 m was used. Three laboratory experiments were conducted. The experiments consisted...

Certain laboratory tests require a gas source with a stable pressure. Commercially available gas pressure regulators address the above requirement. However, the accuracy of these devices is often insufficient and what is more, the market offer of accurate gas pressure regulators is limited. Moreover, the commercially available gas pressure regulato...
