Synthesis of mesoporous materials for carbon dioxide sequestration

High temperature CO2 sorption using Ca(OH)2 in pilot scale packed column

“…Many methods are employed to separate CO2 from entering into atmosphere, but sorption method [3] was found to be more economical and simplest [4]. Zeolites, persovskites, hydrotalicites, soda lime, polymeric membranes, fcu-MOF based rare-earth metals and also metal oxides like lithium zirconates, lithium potassium zirconates, sodium metasilicates, etc., are used as a sorbents to capture or separate CO2 from the atmosphere [5][6][7][8]. Usually the metal oxides used as adsorbents for the removal of CO2 from the flue gas and atmosphere, forms respective solid metal carbonates [9][10][11].…”

Near-Zero Emissions Oxy-Combustion Flue Gas Purification

“…Macario et al (47) synthesized mesoporous material in pure silica form (MCM-41 and MCM-48) containing Al, Fe, Cu and Zn. These materials have high CO 2 adsorption capacity, high selectivity and high working capacity.…”

NMR studies of methane and hydrogen in microporous materials

“…The efficiencies of various nanoporous and microporous materials for storage and ease of removal depend crucially on the thermodynamic properties of these gases at or near the surfaces of the chosen materials [8][9][10][11][12]. These properties and the characteristic dynamics are also important in the development of methods for CO 2 sequestration [13][14][15]. There is considerable documentation in the literature about the total absorption properties of light gases (such as hydrogen and methane) on various porous materials but there is little information about the detailed dynamics of the gases in the confined geometries or about their interactions with the walls of the confinement.…”
