Optimization of selection of chain amine scrubbers for CO2 capture
(
Springer Verlag
, 2014 , Article)
In order to optimize the selection of a suitable amine molecule for CO2 scrubbers, a series of ab initio calculations were performed at the B3LYP/6-31+G(d,p) level of theory. Diethylenetriamine was used as a simple chain ...
Reaction kinetics of carbon dioxide with aqueous solutions of l-Arginine, Glycine & Sarcosine using the stopped flow technique
(
Elsevier
, 2017 , Article)
The use of amino acids as potential solvents for carbon dioxide (CO2) capture has been considered by a number of researchers. However, very little is known about the kinetics and mechanism of amino acids-CO2 reactions. In ...
Reaction kinetics of carbon dioxide in aqueous blends of N-methyldiethanolamine and L-arginine using the stopped-flow technique
(
MDPI AG
, 2019 , Article)
Reduction of carbon dioxide emission from natural and industrial flue gases is paramount to help mitigate its effect on global warming. Efforts are continuously deployed worldwide to develop efficient technologies for CO ...
Kinetics of CO2 Adsorption/Desorption of Polyethyleneimine-Mesoporous Silica
(
Wiley-VCH Verlag
, 2017 , Article)
The kinetics of adsorption of CO2 on solid sorbents based on polyethyleneimine/mesoporous silica (PEI/MPS) was studied by following the mass gain during CO2 flow. Linear (PEI-423) and branched (PEI-10k) polymers were ...
Carbamate Formation and Amine Protonation Constants in 2-Amino-1-Butanol–CO2–H2O System and Their Temperature Dependences
(
Springer New York LLC
, 2018 , Article)
The apparent protonation constant of an amino butanol (AB) and its carbamate formation constant in the CO2–H2O–AB system were determined at T = 298.15–328.15 K, and at various ionic strengths up to 0.2 mol·L−1 by potentiometric ...
Reaction Kinetics of Carbon Dioxide (CO2) with Diethylenetriamine and 1-Amino-2-propanol in Nonaqueous Solvents Using Stopped-Flow Technique
(
American Chemical Society
, 2016 , Article)
In this work, the reaction kinetics of carbon dioxide (CO2) with diethylenetriamine (DETA) and 1-amino-2-propanol (1-AP) in methanol and ethanol systems were measured using the stopped flow technique over a temperature ...
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 ...
Potential use of mixed indigenous microalgae for carbon dioxide bio-fixation and advanced wastewater treatment
(
AIChE
, 2017 , Conference Paper)
The potential use of mixed indigenous microalgae (MIMA) as a CO2 capturing technology and treatment process for wastewaters was evaluated at two temperatures ( 25 and 30 C) and different CO2 dosage ( 0%, 5% and 15%). During ...
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 ...
