Operando Raman spectroscopic studies of lithium zirconates during CO2 capture at high temperature
(Royal Society of Chemistry, 2016-01)
Li2ZrO3 based sorbents were synthesized for CO2 capture at high temperature between 500 and 700 C. Monoclinic ZrO2, tetragonal Li2ZrO3, Li2 CO3, K2CO3 and LiKCO3 phases were detected by XRD and Raman spectroscopy. The ...
Cost-based comparison of multi-stage membrane configurations for carbon capture from flue gas of power plants
(Elsevier, 2019-07)
An optimization study of membrane-based separation systems for carbon dioxide capture from flue gas of power plants is conducted, considering the possibility of employing up to four stages and using diverse options to ...
CO2capture properties of Li4SiO4after aging in air at room temperature
(Elsevier, 2020-05)
In this study, we evaluated the physicochemical stability of lithium orthosilicate (Li4SiO4) powders after aging in air. Thermogravimetric (TG) analysis in CO2flow evidences that as-milled Li4SiO4stored in a closed plastic ...
Renewable and Electroactive Biomass-Derived Tubes for CO2Capture in Agroindustrial Processes
(American Chemical Society, 2021-06)
Tube-shaped renewable carbon materials were developed to work as separation agents for CO2 capture in agroindustrial and intensive farming facilities. The tubes have electrical properties and moderate CO2 adsorption ...
Analysis of a Batch Adsorber Analogue for Rapid Screening of Adsorbents for Postcombustion CO 2 Capture
(American Chemical Society, 2019-02)
A simplified proxy model based on a well-mixed batch adsorber for vacuum swing adsorption (VSA) based CO2 capture from dry post-combustion flue gas is presented. A graphical representation of the model output allows for ...
K-doping effect in the kinetics of CO2 capture at high temperature over lithium silicates obtained from rice husks: in situ/operando techniques
(Elsevier, 2021-01)
K-doped lithium silicates were synthesized as CO2 sorbents using rice husks as silica source. Two different doping methods were used to prepare the solids, incipient wetness impregnation and co-impregnation. Noticeable ...
Adsorption microcalorimetry applied to the characterisation of adsorbents for CO 2 capture
(John Wiley & Sons Inc, 2012-12)
The present work presents the design, assembly and experimental validation of a microcalorimetric device coupled to a volumetric adsorption setup applied to the characterisation of adsorbents for carbon dioxide (CO 2) ...
Separation of CO2 from CH4 and CO2 capture in the presence of water vapour in NOTT-400
(Royal Society Of Chemistry, 2015-01-16)
From a binary equimolar gas-mixture of CO2 and CH4, NOTT-400 shows CO2 separation from CH4. By kinetic uptake experiments, this material confirms a maximum of 4.3 wt% CO2 capture at 30 8C and a significant 2-fold increase ...
Post-combustion CO2 capture process: Equilibrium stage mathematical model of the chemical absorption of CO2 into monoethanolamine (MEA) aqueous solution
(Institution of Chemical Engineers, 2011-09)
This paper deals with the modeling and optimization of the chemical absorption process to CO2 removal using Monoethanolamine (MEA) aqueous solution. Precisely, an optimization mathematical model is proposed to determine ...
