Journal ArticleDOI
Adsorbents for the post-combustion capture of CO2 using rapid temperature swing or vacuum swing adsorption
TL;DR: In this paper, the authors highlight the issues related to adsorption in post-combustion capture of CO2 and present a review of the impact of these issues on the performance of the adorption process.
Journal ArticleDOI
Proto-calcite and proto-vaterite in amorphous calcium carbonates.
Denis Gebauer,Philips N. Gunawidjaja,J. Y. Peter Ko,Zoltán Bacsik,Baroz Aziz,Lijia Liu,Yongfeng Hu,Lennart Bergström,Cheuk-Wai Tai,Tsun-Kong Sham,Mattias Edén,Niklas Hedin +11 more
TL;DR: Amorphous order: Amorphous calcium carbonates (ACC) have an intrinsic structure relating to the crystalline polymorphs of calcite and vaterite and the proto-crystalline structures of calcium carbonate and calcite.
Journal ArticleDOI
Structuring adsorbents and catalysts by processing of porous powders
TL;DR: In this article, the requirements and important properties of hierarchically porous structures are reviewed with a focus on applications in gas separation and catalysis, and their performance is compared with traditional binder-containing structured adsorbents.
Journal ArticleDOI
Mechanisms and Kinetics for Sorption of CO2 on Bicontinuous Mesoporous Silica Modified with n-Propylamine
Zoltán Bacsik,Nanna Ahlsten,Asraa Ziadi,Guoying Zhao,Alfonso E. Garcia-Bennett,Belén Martín-Matute,Niklas Hedin +6 more
TL;DR: In situ FTIR spectroscopy showed that the amine groups reacted with CO2 and formed ammonium carbamate ion pairs as well as carbamic acids under both dry and moist conditions, and distinct evidence for a fourth and irreversibly formed moiety was observed under sorption of CO2 under dry conditions.
Journal ArticleDOI
Sorbents for CO 2 capture from flue gas—aspects from materials and theoretical chemistry
TL;DR: The nanoscale sorbent materials that have been developed and the theoretical basis for their function in CO(2) separation, particularly from N(2)-rich flue gases are reviewed.
