Investigation of Moisture Effect on Methane Adsorption Capacity of Shale Samples
Fuel, 2018 Abstract The existing moisture in shale samples makes the evaluation for shale gas reservoirs more difficult due to its impact on the methane adsorption capacity and pore structure measurements. This paper compares the pore structure characteristics and methane adsorption capacity between dry and wet shale samples from Perth Basin, Western Australia.

Three Stages of Methane Adsorption Capacity Affected by Moisture Content
Fuel, 2018Abstract Methane adsorption capacity is a key factor in determining shale gas in place (GIP) – requiring that it is determined under in situ moisture conditions. Current methods may be insufficient to investigate these exact characteristics when applied to actual reservoirs with high or variable moisture contents. We propose a heating and cooling (HC)

Abstract Shale generally contains water that has a significant effect on the adsorption of methane in shale. Since methane in shale is mostly stored in an adsorbed state, understanding the effect of moisture on shale adsorption behavior will play a vital role in shale gas development.

Methane capacities of Zonguldak coals and the factors affecting methane adsorption
Mining Science and Technology, 1991Abstract This study aimed to establish methane adsorption isotherms for coal samples taken from four different seams in Kozlu district, Zonguldak Coalfield, Turkey. The quantity of methane adsorbed by these samples, at different gas pressures up to 45 atm, was determined and the results were discussed in relation to the gas capacities of these coals.

Coalbed methane (CBM) is primarily stored and transported through the pores in the coal matrix, making it essential to study the development of different scales of pores in coal to better understand the evaluation and exploration of CBM. In this study, four coal samples of varying ranks (Ro,max = 0.68%-2.86%) were selected, and different scale pores ...

Capacity and Thermodynamic Nomograph for an Adsorption Methane Storage System
Chemical and Petroleum Engineering, 2016General equations for calculation of the capacity and thermodynamic properties of adsorption methane storage systems were written. Experimental results for methane adsorption on AU-1 adsorbent were analyzed and plotted in the nomograph of capacity and thermodynamic properties of the adsorbent–adsorbate–gas adsorption system.

Evolution Mechanism of Methane Adsorption Capacity in Vitrinite-Rich Coal During Coalification
Journal of Natural Gas Science and Engineering, 2021Abstract In this study, the evolution of methane adsorption capacity was investigated by analyzing both naturally matured coal samples and samples that matured by pyrolysis to different ranks. Methane adsorption isotherms, mercury injection, and small-angle X-ray scattering experiments were employed to characterize the methane adsorption capacity and

The Langmuir adsorption model cannot well describe the methane adsorption characteristics of dark lignite and meta-anthracite. Aiming to solve this problem, an adsorption model was derived on the basis of adsorption potential theory. Its prediction capacity was also studied in terms of methane adsorption isotherms on a wide variety of coals and ...

Evaluation and analysis of methane adsorption capacity in deep‐buried coal seams
Greenhouse Gases: Science and Technology, 2022AbstractIn this work, the high‐pressure methane adsorption/desorption tests were conducted in four coal samples (from low‐rank bituminous coal to anthracite) under different temperature and pressure conditions to reveal the mechanism of desorption hysteresis effect in the deep‐buried coal seams.

A simulation model of a high-capacity methane adsorptive storage system
Adsorption, 1995A two-dimensional model is developed to describe the hydrodynamics, heat transfer and adsorption phenomena associated with the adsorptive storage of natural gas (NG) in cylindrical reservoirs. Intraparticle and film resistances to both heat and mass transfer are neglected.
