Co2 Adsorption by Surface Modified Carbon Sorbents
Anthropogenic emissions have increased the CO2 concentration on the atmosphere with over 30% compared to pre-industrialize levels [1]. Most of these anthropogenic emissions are caused by fossil fuel utilization, where around one-third is due to electricity generation from fossil fuel combustion, mainly from coal-fired units. Furthermore, fossil fuel electricity generation units rank as the firs...
متن کاملCO2 adsorption by activated templated carbons.
Highly porous carbons have been prepared by the chemical activation of two mesoporous carbons obtained by using hexagonal- (SBA-15) and cubic (KIT-6)-ordered mesostructured silica as hard templates. These materials were investigated as sorbents for CO(2) capture. The activation process was carried out with KOH at different temperatures in the 600-800°C range. Textural characterization of these ...
متن کاملLow pressure adsorption of CO2 on multi-wall carbon nanotubes
Volumetric techniques were employed to study the adsorption of CO2 on a purified multi-wall carbon nanotubes (MWNT’s) sample, as a mesoporous material, at isothermal conditions of 288, 293 and 298 K and pressures ranging from 30 to 150 kPa. Langmuir, Freundlich and Sips equations were used to represent the isotherms. Also the parameters of these fitted isotherm models have been determined. The ...
متن کاملImproving CO2 adsorption with new amine-functionalized Y-type zeolite
In this work, a new synthesized Y-type zeolite with an Si/Al molar ratio of 2.5 (NaY) was modified with amines, in order to probe the influence of the modification of the adsorbent’s surface on CO2 adsorption. The three selected amines were diethanolamine, tetraethylenepentamine, and 2- methylaminoethanol. The surface nature of NaY was changed after amine modification, which causes a...
متن کاملOptimization of CO2 adsorption capacity and cyclical adsorption/desorption on tetraethylenepentamine-supported surface-modified hydrotalcite.
The objective of this research was to investigate CO2 adsorption capacity of tetraethylenepentamine-functionalized basic-modified calcined hydrotalcite (TEPA/b-cHT) sorbents at atmospheric pressure formed under varying TEPA loading levels, temperatures, sorbent weight to total gaseous flow rate (W/F) ratios and CO2 concentrations in the influent gas. The TEPA/b-cHT sorbents were characterized b...
