Anisotropic Permeability Model for Coal Considering Stress Sensitivity, Matrix Anisotropic Internal Swelling/Shrinkage, and Gas Rarefaction Effects [PDF]
, 2023 Permeability is the most crucial property of coal in relation to coalbed methane production and CO2 sequestration. Due to coal’s anisotropic structure and mechanical properties, its permeability exhibits strong anisotropy.

Journal of Materials Research and Technology, 2023 In the present day, we have reached close to an optimum condition of CO2 emission when using coal or coke for iron making process. Carbon neutrality is achieved during carbothermal reduction by employing biomass as a reducing agent in composite pellets ...

Role of adsorption and swelling on the dynamics of gas injection in coal [PDF]
Journal of Geophysical Research: Solid Earth, 2009 An experimental technique is presented to perform gas injection experiments on coal cores confined by an external hydrostatic pressure, which makes use of the so‐called transient step method. The experiments are intended to improve the knowledge on the different mechanisms acting during CO2 storage in coal seams, in particular, those related to ...
