Hydrogen storage and diffusion in shale nanopores: molecular dynamics effects of pressure, temperature, confinement, and wall chemistry

Frontiers in Earth Science
IntroductionUnderground hydrogen storage in shale is governed by pore occupancy, interfacial interactions, and molecular diffusion. This study examines their combined effects on hydrogen retention and transport.MethodsMolecular dynamics simulations were ...

Effect of Kerogen Type and Maturity on Performance of Carbon Dioxide Storage in Shale

, 2017
Potential for sequestration of carbon dioxide in organic rich shale is investigated in this work. Adsorption isotherms and Onsager diffusion coefficients are determined using molecular dynamics simulations for atomistic kerogen models.

The kerogen vanadyl porphyrins: Incorporation during catagenesis

, 1999
Natural vanadyl (VO 2+)-deoxophylloerythroetioporphyrins (DPEP) have been shown to be capable of reacting and quantitatively incorporating into immature kerogen model materials (torbanite, lignites, subbituminous coal and immature lacustrine ...

Kerogen

, 2003
[Extract] Kerogen is the solid, high molecular-weight fraction of sedimentary organic matter (OM) that is insoluble in organic solvents (e.g. chloroform) as oppoosed to the soluble fraction called bitumen.

Structural characterization of Green River oil shale core segments and the kerogen isolated from these segments

, 2011
presentationThe goal is to obtain information about chemical structure of oil shale and its kerogen. This includes chemical characterization of the shale, the isolated kerogen, and the products of pyrolysis of both the shale and kerogen, and provides ...

Research on the Adsorption Characteristics of Shale Gas in Different Types of Kerogen

To investigate the methane adsorption characteristics in different types of kerogen, microscopic models for three kerogen types—sapropelic (Type I), mixed (Type II), and humic (Type III)—were developed in this paper based on the paradigm ...

Characterizing competitive adsorption and diffusion of methane and carbon dioxide in kerogen type-III slit model

Clarifying methane’s adsorption and diffusion properties in kerogen contributes to efficiently exploiting shale gas reservoirs. We refined the kerogen III-series model to construct the kerogen III-B and kerogen III-C molecular structures.
