Effect of Kerogen Thermal Maturity on Methane Adsorption Capacity: A Molecular Modeling Approach. [PDF]
Molecules, 2020 The presence of kerogen in source rocks gives rise to a plethora of potential gas storage mechanisms. Proper estimation of the gas reserve requires knowledge of the quantities of free and adsorbed gas in rock pores and kerogen. Traditional methods of reserve estimation such as the volumetric and material balance approaches are insufficient because they

Methane Adsorption on Aggregates of Fullerenes: Site‐Selective Storage Capacities and Adsorption Energies [PDF]
ChemSusChem, 2013 AbstractMethane adsorption on positively charged aggregates of C60 is investigated by both mass spectrometry and computer simulations. Calculated adsorption energies of 118–281 meV are in the optimal range for high‐density storage of natural gas. Groove sites, dimple sites, and the first complete adsorption shells are identified experimentally and ...
