Effect of strain on gas adsorption in tight gas carbonates: A DFT study
(
Elsevier B.V.
, 2021 , Article)
The geometrical properties of the reservoir rocks are usually affected by natural thermodynamics or environmental changes. These factors may modify the distribution and the amount of gas in place in the reservoir. To address ...

Synthesis, characterization, and application of Ce0.9Ln0.05Ag0.05O2−δ materials (where, Ln = La, Pr, Nd, Sm, Gd, Tb, Dy, Er) for the thermochemical conversion of CO2 reported in this paper. The Ce0.9Ln0.05Ag0.05O2−δ materials ...
Adsorption of CO2 on Cu/SiO2 nano-catalyst: Experimental and theoretical study
(
Elsevier B.V.
, 2022 , Article)
Copper-based silica is a promising catalyst for several reaction pathways for CO2 conversion to hydrocarbons. The activity of this catalyst in terms of conversion and product selectivity is affected by CO2 adsorption, ...
Impact of clays on CO2 adsorption and enhanced gas recovery in sandstone reservoirs
(
Elsevier Ltd
, 2021 , Article)
Carbon dioxide enhanced gas recovery (EGR) is a promising technique to sequester CO2 and boost natural gas recovery from conventional depleted and unconventional tight gas reservoirs. Clay minerals are usually present in ...
Influence of natural gas composition on adsorption in calcite Nanopores: A DFT study
(
Elsevier B.V.
, 2021 , Article)
Density functional theory is used to study the adsorption of natural gas components in calcite (10.4) cylindrical nanopores with 1–4 nm diameters. The change of adsorption energy with the diameter of the nanopores is studied ...
Carbon dioxide EGR and sequestration in mature and immature shale: Adsorption study
(
Elsevier B.V.
, 2020 , Article)
Recently, CO2 sequestration in different shale formations has become an attractive option owing to the abundance of shale basins. However, these formations have different maturity levels and contain a variety of minerals ...

(
Elsevier B.V.
, 2021 , Article)
In this work, the interaction of methane and carbon dioxide on α-quartz with surface 001, with a siloxane termination (dense) surface was investigated by means of Ab-Initio Molecular Dynamics. Different temperatures were ...
A theoretical study of gas adsorption on calcite for CO2 enhanced natural gas recovery
(
Elsevier B.V.
, 2020 , Article)
The adsorption of gas molecules (CO2, CH4, H2O, H2S and N2) on calcite (104) has been studied by means of Density Functional Theory for molecular characterization of Enhanced Gas Recovery (EGR) CO2 injection. Results show ...
CO2 enhanced gas recovery and sequestration in depleted gas reservoirs: A review
(
Elsevier B.V.
, 2021 , Article Review)
Increasing CO2 emissions and global warming side effects have prompted the researchers to look for safe and reliable storage sites that have high capacity. Among the available CO2 capturing sinks, depleted gas reservoirs ...
Influence of carbon uniformity on its characteristics and adsorption capacities of CO2 and CH4 gases
(
MDPI AG
, 2021 , Article)
Activated carbons of resorcinol-formaldehyde aerogels (AC-RFA) were prepared and mixed with multiwall carbon nanotubes (MWCNTs) with various ratios. Samples were characterized by different techniques. The novelty of the ...
