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 ...
Enhancing oil removal from water using ferric oxide nanoparticles doped carbon nanotubes adsorbents
(
Elsevier B.V.
, 2016 , Article)
Oil contaminated water is one of the challenges in water resources management. It is crucial to remove the oil droplets from water in order to meet the discharge regulations set by the environmental authorities. Carbon ...
Enhanced Removal of Diesel Oil Using New Magnetic Bentonite-Based Adsorbents Combined with Different Carbon Sources
(
Springer Science and Business Media Deutschland GmbH
, 2022 , Article)
In this work, new magnetic bentonite-based adsorbents combined with different carbon sources, namely, reduced graphene oxide and multiwall carbon nanotubes, were synthesized via co-precipitation method. The synthesized ...
Comparative study between adsorption and membrane technologies for the removal of mercury
(
Elsevier B.V.
, 2021 , Article)
Mercury is one of the most detrimental by-products of industrial activities, such as mining and fossil fuel combustion. What differentiates this contaminant from other pollutants is its bioaccumulation and rapid distribution ...
Adsorption of 4-Nitrophenol onto Iron Oxide Bentonite Nanocomposite: Process Optimization, Kinetics, Isotherms and Mechanism
(
Springer Science and Business Media Deutschland GmbH
, 2022 , Article)
Despite its importance in chemical industry, 4-Nitrophenol (4-NP) is a persistent organic pollutant that has serious effects on the ecosystem. In the present study, Box–Behnken design in response surface methodology was ...
CO2 sorption kinetics of scaled-up polyethylenimine-functionalized mesoporous silica sorbent
(
American Chemical Society
, 2015 , Article)
Two CO2 solid sorbents based on polyethylenimine, PEI (Mn ∼ 423 and 10K), impregnated into mesoporous silica (MPS) foam prepared in kilogram quantities via a scale-up process were synthesized and systematically characterized ...
Synthesis of nanostructured novel ion-imprinted polymer for selective removal of Cu2+ and Sr2+ ions from reverse osmosis concentrated brine
(
Elsevier
, 2023 , Article)
This study aims to prepare an ion-imprinted polymer (IIP) using copper sulfate as a template and potassium persulfate as an initiator to selectively adsorb copper ions (Cu2+) from aqueous solutions and in an attempt to ...
The recovery of strontium ions from seawater reverse osmosis brine using novel composite materials of ferrocyanides modified roasted date pits
(
Elsevier
, 2023 , Article)
In this study, three types of adsorbents were used to remove and recover strontium ions (Sr2+) from aqueous and brine solution of seawater reverse osmosis (SWRO), namely roasted date pits (RDP) and RDP modified using copper ...
Iron Sulfide Scale Inhibition in Carbonate Reservoirs
(
American Chemical Society
, 2022 , Article)
Hydrocarbon production operations include water injection, varying stimulation approaches, and enhanced oil recovery techniques. These treatments often affect reservoir formation, production, and injection facilities. Such ...
