Abstract Ventilation Air Methane emissions (VAM) from coal mines lead to environmental
concern because their high global warming potential and the loss of methane resources …

Methane (CH4) is the second most important greenhouse gas after carbon dioxide (CO2),
but its global warming potential is 21–28 times that of CO2. Coal mining accounts for 9% of …

As a major greenhouse gas, methane, which is directly vented from the coal‐mine to the
atmosphere, has not yet drawn sufficient attention. To address this problem, we report a …

Efficient separation of the CH4/N2 mixture is of great significance for coalbed methane
purification. It is an effective strategy to separate this mixture by tuning the van der Waals …

Coal mine methane (CMM) with the worldwide reserves of 2.6× 1014 m3 is one of the
important unconventional natural gases. However, most of the low-concentration coal mine …

Selectively separating CH4 from N2 in natural gas purification is extremely important, but
challenging. Herein, a copper‐based metal–organic framework (MOF) NKMOF‐8‐Me with …

The adsorption equilibria and kinetics of CO 2, CO, N 2, CH 4, Ar and H 2 on zeolite 13X
were measured via the volumetric method at 293, 308 and 323 K and up to 1.0 MPa …

The evolutions of spherical flame of methane/air/diluent mixtures in a cylindrical chamber
were observed by setting different equivalence ratios ϕ and diluent volume fraction V …

Reduction of zeolite crystal size from the micron scale to the nanoscale leads to a significant
increase in specific surface area, favoring mass-transfer pathways. Here, we have prepared …

Lowering the atmospheric methane concentration is critical to reducing short-term global
warming because of methane's high radiative forcing and relatively short lifetime. Methane …
