Factors controling the SO2 removal by porous carbons: relevance of the SO2 oxidation step
Encarnacion Raymundo-Piñero,Diego Cazorla-Amorós,C. Salinas-Martínez de Lecea,Angel Linares-Solano +3 more
TL;DR: In this article, the SO2 retention in presence of O2 at room temperature was analyzed using temperature programmed desorption (TPD) and H2 temperature programmed reaction experiments.
Journal ArticleDOI
Adsorption of SOx by oxide materials: A review
TL;DR: A review of the literature devoted to the wide variety of sorbent systems that are currently either in use or under laboratory investigation for the removal of the SOx (SO2+SO3) from flue gases is provided in this article.
Journal ArticleDOI
Adsorption of sulfur dioxide on ammonia-treated activated carbon fibers
TL;DR: In this article, the role of pore size, pore volume, and pore surface chemistry on adsorption of sulfur dioxide and its catalytic conversion to sulfuric acid was investigated.
Journal ArticleDOI
Removal of elemental mercury by bamboo charcoal impregnated with H2O2
TL;DR: In this paper, the adsorptive potential of BC and modified BC using H2O2 for elemental mercury was investigated for the first time through a parametric study conducted with a bench-scale bed.
Journal ArticleDOI
Removal of SO2 by activated carbon fibers in the presence of O2 and H2O
TL;DR: In this article, the authors describe the potential capability of activated carbon fibers (ACFs) in continuously removing SO2 from inert atmosphere without requiring further regeneration, and a tubular reactor packed with ACF was used to study the conversion of SO2 into H2SO4 in the presence of O2 and H2O.

Journal ArticleDOI
The importance of active surface area in the carbon-oxygen reaction1,2
TL;DR: In this article, the authors measured the coverage of the surface with oxygen complex upon exposure of the samples to O2 at 300 deg for 24 hours, and calculated the unoccupied active surface area of the oxidized samples.
Journal ArticleDOI
Importance of carbon active sites in the gasification of coal chars
TL;DR: In this paper, a demineralized lignite has been used in a fundamental study of the role of carbon active sites in coal char gasification, where the chars were prepared in N 2 under a wide variety of conditions of heating rate (10 K min −1 to 10 4 K s −1 ), temperature (975 − 1475 K) and residence time (0.3 s-1 h).
Journal ArticleDOI
Temperature-Programmed Desorption and Reaction: Applications to Supported Catalysts
TL;DR: In this paper, a temperature-programmed desorption (TPD) experiment on a supported metal catalyst is described, where a small amount of catalyst (10-200 mg) is contained in a reactor that can be heated by a furnace.
Journal ArticleDOI
The chemical reactivity of carbons
TL;DR: A review of the type of surface groups observed and of the radical reactions occurring on carbon surfaces is given in this paper, where the authors also discuss the role of the surface groups in the formation of radical reactions.
Journal ArticleDOI
On the kinetics of carbon (Char) gasification: Reconciling models with experiments
TL;DR: In this article, the authors analyzed the gasification reactivity profiles of different carbons (chars) from both a theoretical and an experimental point of view, and provided the heretofore elusive quantitative experimental explanation of reactivity variations with conversion for char gasification in carbon dioxide.
