The availability of commercial gravimetric and volumetric systems for the measurement of
adsorption equilibrium has seen also a growth of the use of these instruments to measure …

Shale gas, as a promising alternative energy source, has received considerable attention
because of its broad resource base and wide distribution. The establishment of shale …

Diffusion coefficient is one of the key parameters determining the coalbed methane (CBM)
reservoir economic viability for exploitation. Diffusion coefficient of coal matrix controls the …

Chinese coal seams are characterized by high gas content and low permeability. The
permeability of coal seams should be improved to achieve maximum extraction of coalbed …

The transport of CO 2–CH 4 mixture in coal nanopores is crucial to CO 2-enhanced coalbed
(CO 2-ECBM) recovery, but is highly challenging on adsorption-diffusion dominated …

Using molecular dynamics, we simulated the diffusion behavior of supercritical methane in
shale nanopores composed of different matrix mineral types (organic matter, clay, and …

CO2 molecular diffusion in subsurface porous media is one of the key mechanisms in high-
pressure–high-temperature CO2 geosequestration and CO2-based enhanced oil recovery …

Many gas emission accidents have occurred in the Zhaozhuang coal mine in recent years,
so an experiment and simulation study on Zhaozhuang coal adsorption of gas were …

A total of four samples with different coal ranks were exposed to supercritical CO 2 (SC–CO
2) fluids for one week at 313.15 K and 12 MPa. FTIR and X-ray diffraction were combined to …

Carbon dioxide enhanced coalbed methane recovery (CO2-ECBM) has been proposed as a
promising technology for the natural gas recovery enhancement as well as mitigation of CO2 …
