Journal ArticleDOI
Reversible Exsolution of Dopant Improves the Performance of Ca2Fe2O5 for Chemical Looping Hydrogen Production
Davood Hosseini,Felix Donat,Paula M. Abdala,Sung Min Kim,Agnieszka M. Kierzkowska,Christoph R. Müller +5 more
TL;DR: Having the potential of converting a larger fraction of steam to H2 than pure iron oxide in addition to its higher reactivity with CH4, the doped calcium-iron-based oxygen carrier is a promising material for chemical looping H2 production.
Journal ArticleDOI
Ca–Cu looping process for CO2 capture from a power plant and its comparison with Ca-looping, oxy-combustion and amine-based CO2 capture processes
Dursun Can Ozcan,Arturo Macchi,Dennis Y. Lu,Agnieszka M. Kierzkowska,Hyungwoong Ahn,Christoph R. Müller,Stefano Brandani +6 more
TL;DR: In this article, the technical performance of an advanced configuration of the Ca-looping process, called Ca-Cu looping, for the reduction of CO 2 emissions from a subcritical CFB power plant with a net output of 250MW e.
Journal ArticleDOI
In Situ XRD and Dynamic Nuclear Polarization Surface Enhanced NMR Spectroscopy Unravel the Deactivation Mechanism of CaO-Based, Ca3Al2O6-Stabilized CO2 Sorbents
Sung Min Kim,Wei-Chih Liao,Agnieszka M. Kierzkowska,Tigran Margossian,Davood Hosseini,Songhak Yoon,Marcin Broda,Christophe Copéret,Christoph R. Müller +8 more
TL;DR: In this paper, a combined use of in situ XRD together with textural and morphological characterization techniques (SEM, STEM, and N2 physisorption) and solid-state 27Al NMR (in particular dynamic nuclear polarization surface enhanced NMR spectroscopy, DNP SENS) was shown how microscopic changes trigger the sudden onset of deactivation of Ca3Al2O6-stabilized CaO.
Journal ArticleDOI
CuO promoted Mn2O3-based materials for solid fuel combustion with inherent CO2 capture
Davood Hosseini,Qasim Imtiaz,Paula M. Abdala,Songhak Yoon,Agnieszka M. Kierzkowska,Anke Weidenkaff,Christoph R. Müller +6 more
TL;DR: In this paper, a novel bimetallic Cu-Mn oxygen carrier for chemical-looping with oxygen uncoupling (CLOU) based CO2 capture is presented.
Journal ArticleDOI
Coprecipitated, copper-based, alumina-stabilized materials for carbon dioxide capture by chemical looping combustion.
TL;DR: The oxygen-carrying capacity of the synthesized oxygen carriers was found to be strongly influenced by both the precipitating agent and the pH at which the precipitation was performed; however, all oxygen carriers tested showed a stable cyclic oxygen- Carrying capacity.
