Journal ArticleDOI
CO2 Uptake and Cyclic Stability of MgO-Based CO2 Sorbents Promoted with Alkali Metal Nitrates and Their Eutectic Mixtures
Alessandro Dal Pozzo,Alessandro Dal Pozzo,Andac Armutlulu,Margarita Rekhtina,Paula M. Abdala,Christoph R. Müller +5 more
TL;DR: In this article, MgO is used to stabilize or even reduce the atmospheric concentration of the greenhouse gas CO2, to mitigate climate change, and the authors propose a solution for CO2 capture and storage.
Journal ArticleDOI
Peering into buried interfaces with X-rays and electrons to unveil MgCO3 formation during CO2 capture in molten salt-promoted MgO.
Alexander H. Bork,Margarita Rekhtina,Elena Willinger,Pedro Castro-Fernández,Jakub Drnec,Paula M. Abdala,Christoph R. Müller +6 more
TL;DR: In this paper, the growth mechanism of MgCO3 under practically relevant conditions using a well-defined, yet representative, model system that is a MgO(100) single crystal coated with NaNO3.
Journal ArticleDOI
CO2 Uptake Potential of Ca-Based Air Pollution Control Residues over Repeated Carbonation–Calcination Cycles
TL;DR: In this paper, the potential of fly ash residues as CO2 sorbents in the calcium looping process was investigated in waste-to-energy (W2E) plants.
Journal ArticleDOI
NiCuMo-SiO2 catalyst for pyrolysis oil upgrading: Model acidic treatment study
M. V. Alekseeva (Bykova),Daria Otyuskaya,Margarita Rekhtina,Olga A. Bulavchenko,O. А. Stonkus,V. V. Kaichev,S. G. Zavarukhin,Joris W. Thybaut,Vaios Alexiadis,Robertus Hendrikus Venderbosch,V.А. Yakovlev +10 more
TL;DR: In this article, the deactivation of catalysts by acidity of pyrolysis liquid is studied by treating newly developed NiCuMo-SiO2 catalysts in 1'M acetic acid water solution.
Journal ArticleDOI
Effect of molten sodium nitrate on the decomposition pathways of hydrated magnesium hydroxycarbonate to magnesium oxide probed by in situ total scattering
Margarita Rekhtina,Alessandro Dal Pozzo,Alessandro Dal Pozzo,Dragos Stoian,Andac Armutlulu,Felix Donat,Maria Valeria Blanco,Zhu-Jun Wang,Marc Georg Willinger,Alexey Fedorov,Paula M. Abdala,Christoph R. Müller +11 more
TL;DR: It is demonstrated that molten NaNO3 facilitates the release of water (from both water of crystallization and through dehydroxylation) and decarbonation, and promotes the crystallization of MgCO3 and MgO in comparison to pristine HM.
