Producing CH 4 from coal beds and shale reservoirs is an attractive unconventional energy
option. Injecting CO 2 into a coal or shale basin can extract more CH 4 and enable the …

To reveal the change of coal strain during N 2/CO 2–ECBM, four coal samples (R o, ran=
0.42–3.23%) were prepared with different CH 4 saturations, and the physical simulation …

Carbon dioxide (CO2)-enhanced coalbed methane recovery (CO2-ECBM) is a critical way to
increase methane production and reduce greenhouse gas (CO2 and CH4) emissions. As …

In this paper, the pore structures of three different rank coals sampled from China
(anthracite, bituminous coal and lignite) were characterized by CO 2 and N 2 adsorption …

Coupled coal–gas interaction in coal seams is crucial to the efficient recovery of Coalbed
methane (CBM), and carbon dioxide-enhanced CBM (CO2-ECBM). Coal is physically …

Large-scale hydrogen underground storage is widely considered as an important solution
for energy transition to mitigate global warming, however, our understanding on the various …

To study the influence of coal metamorphism on the pore system development
characteristics of deep coal reservoirs, coal samples of different ranks were collected as …

Coalbed methane (CBM) is a potential green energy supply for addressing the worldwide
energy crisis. However, the recovery of economically viable amounts of methane requires …

The displacement mechanisms of adsorbed CH 4 by injected CO 2 at high pressures in CO
2-enhanced coalbed methane (CO 2-ECBM) processes involve competitive adsorption …

Methane is primarily stored in coal matrix pores and pore size distribution has an important
effect on gas adsorption/desorption. Investigation of the relationship between pore size …
