Rational Design of a Multifunctional MOFs for Alkane‐Selective Gas Separation

Advanced Science, Volume 13, Issue 2, 9 January 2026.
The design of a dimethyl‐functionalized adsorbent provides insight into the simultaneous separation of CH4/N2, C2H6/C2H4, and C3H8/C3H6 mixtures. Abstract Efficient separation of light hydrocarbons—including the removal of CH4 from N2 and the purification of olefins such as C2H4 and C3H6 from their corresponding alkanes (C2H6 and C3H8)—is critical in ...

Mitigating Surface Tension Effects in Multi‐Coalbed Methane Reservoirs: Case Study of Liupanshui Field

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Water locking effect caused by surface tension severely restricts coalbed methane (CBM) productivity in multilayer reservoirs. The Songhe demonstration area features main target coal seams with overpressure, high gas content, and high gas saturation, presenting favorable CBM development conditions.

Nanoconfined Methane Storage Mechanism in Deep Coal Seams: A Wettability-Coupled Simplified Local Density Model

Nanomaterials
In deep coal seams, where nanopores (~2 nm) dominate, wettability effects, which govern molecule–wall interaction strength, critically control the methane storage, yet remain poorly understood.

Experimental Study on Multiscale Evolution Mechanism of Coalbed Reservoir Properties in “Three‐Low” CBM Reservoirs Modified by Chlorine Dioxide

Geofluids, Volume 2026, Issue 1, 2026.
Aiming at the “three‐low” challenges (low permeability, low gas saturation, and low critical desorption‐to‐storage ratio [CDSR]) of Chinese coalbed methane (CBM) reservoir materials, this study adopted chlorine dioxide (ClO2) chemical modification on long‐flame, coking, and anthracite coal materials.
