An overview on trace CO2 removal by advanced physisorbent materials
(
Academic Press
, 2020 , Article)
This review paper focuses on various gas processing technologies and materials that efficiently capture trace levels of carbon dioxide (CO2). Fundamental separation mechanisms such as absorption, adsorption, and distillation ...
Graphene-based materials for metronidazole degradation: A comprehensive review
(
Elsevier Ltd
, 2022 , Article)
Due to its cytotoxic effect, metronidazole (MNZ) is a drug commonly used to treat bacterial, protozoal, and microaerophilic bacterial infections. After consumption, it undergoes a series of metamorphic reactions that lead ...
Concurrent adsorption of cationic and anionic dyes from environmental water on amine functionalized carbon
(
IWA Publishing
, 2020 , Article)
Amine functionalized carbon (AFC) was synthesized from raw oil fly ash and later utilized it for simultaneous removal of methyl orange (MO) and rhodamine 6G (Rh6G) pollutant dyes from aqueous medium. AFC was analyzed through ...
Use of nanoadvanced activated carbon, alumina and ferric adsorbents for humics removal from water: isotherm study
(
Springer Nature
, 2020 , Article)
The adsorption of humic substances on three different adsorbents was investigated and adsorption isotherms were applied in this research. The three adsorbents studied include granular activated carbon (GAC), ferric ...
Investigation of the effect of polyelectrolyte structure and type on the electrokinetics and flocculation behavior of bentonite dispersions
(
Elsevier B.V.
, 2017 , Article)
The influence of surface charge type and density, and molecular weight of cationic, anionic and amphoteric polyacrylamide (PAM) on the electrokinetics, adsorption and flocculation behavior of highly stable bentonite ...
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, ...
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 ...
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 ...
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 ...
Effect of surface morphology on methane interaction with calcite: a DFT study
(
Royal Society of Chemistry
, 2020 , Article)
Natural gas, consisting primarily of methane, is found in carbonate reservoirs of which calcite is major component. However, the complexity and heterogeneity of carbonate reservoirs remain a major challenge in estimating ...
