The accurate prediction of gas flow in coals in the field or laboratory requires an accurate model of diffusion within the coal. One major determinant of diffusion rates is the pore size distribution within the coal. In this study, CO2 and CH4 sorpti

Carbon dioxide (CO2) and methane (CH4) vary in their diffusion behaviour in coal, with CO2 being sorbed more extensively and diffusing faster than CH4. Several different mechanisms have been proposed to explain this behaviour. To test these mechanism

An inter-laboratory study of high-pressure gas sorption measurements on two carbonaceous shales has been conducted in order to assess the reproducibility of the sorption isotherms and identify possible sources of error. The measurements were carried

The increasing interest in enhanced coal bed methane (ECBM) production and reporting of greenhouse gas emissions from mines has spotlighted gas diffusion and gas-induced swelling in coals. Although it is generally agreed that carbon dioxide (CO2) dif

Gas diffusion in coals plays an important role in enhanced coalbed methane production, fugitive gas emissions from coal, and gas release in coal mines. However, a consistent picture of diffusion behaviour in coals is yet to emerge. For example, the a
