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 کاملTiO2@PEI-Grafted-MWCNTs Hybrids Nanocomposites Catalysts for CO2 Photoreduction
Anatase (TiO₂) and multiwalled carbon nanotubes bearing polyethylenimine (PEI) anchored on their surface were hybridized in different proportions according to a sol-gel method. The resulting nanocomposites (TiO₂@PEI-MWCNTs), characterized by BET, XRD, XPS, SEM, and UV techniques, were found efficient catalysts for CO₂ photoreduction into formic and acetic acids in water suspension and under vis...
متن کاملMesoporous zinc germanium oxynitride for CO2 photoreduction under visible light.
Mesoporous zinc germanium oxynitride was synthesized by a template-free method at high temperature. Through optimizing redox potentials as well as improving crystallinity, this material showed enhanced activity in CO(2) photoreduction.
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...
