Effect of CO2 content on the natural gas production from tight gas sandstone reservoirs
(
Society of Petroleum Engineers (SPE)
, 2017 , Conference Paper)
The simulation of the gas flow in tight sandstone reservoir is a very complicated process. Several mechanisms contributed to the natural gas production in tight sandstone reservoirs. One of the main mechanisms is the gas ...
Ab-Initio Molecular Dynamics investigation of gas adsorption on α-quartz (001) for CO2 enhanced natural gas recovery
(
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 ...
A critical review of CO2 photoconversion: Catalysts and reactors
(2014 , Article)
Photocatalytic conversion of CO2 to either a renewable fuel or valuable chemicals, using solar energy has attracted more and more attention, due to the great potential to provide an alternative clean fuel and solve the ...
Assessment of CexZryHfzO2 based oxides as potential solar thermochemical CO2 splitting materials
(
Elsevier Ltd
, 2016 , Article)
In this paper, we report the synthesis, characterization, and assessment of CexZryHfzO2 (CZH) materials for solar thermochemical splitting of CO2 in up to 20 consecutive thermochemical cycles. CZH materials with different ...
Sol-gel derived CeO2-Fe2O3 nanoparticles: Synthesis, characterization and solar thermochemical application
(
Elsevier Ltd
, 2016 , Article)
Synthesis of CeO2-Fe2O3 nanoparticles via propylene oxide (PO) aided sol-gel method for the production of solar fuels via thermochemical H2O/CO2 splitting cycles is reported in this paper. For the synthesis of CeO2-Fe2O3, ...
Solar thermochemical conversion of CO2 into synthetic fuels via ferrite based redox reactions
(
AIChE
, 2014 , Conference Paper)
In this contribution, we report the synthesis NiFe2O4 and CoFe2O4 redox materials via sol-gel method. For the synthesis of these materials via sol-gel approach, the Ni, Co, and Fe precursors were first dissolved in ethanol ...
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 ...
Zeolitic imidazolate framework (ZIF-8) based polymer nanocomposite membranes for gas separation
(
Royal Society of Chemistry
, 2012 , Article)
As synthesised ZIF-8 nanoparticles (size ∼ 60 nm and specific surface area ∼ 1300–1600 m2 g−1) were directly incorporated into a model polymer matrix (Matrimid® 5218) by solution mixing. This produces flexible transparent ...
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 ...
