Calcium-looping reforming of methane helps close the anthropogenic carbon cycle directly at large CO 2 stationary sources.
Abstract Amine-functionalized adsorbents offer substantial potential for CO 2 capture owing to their selectivity and diverse application scenarios. However, effectiveness is hindered by low efficiency unstable cyclic performance. Here we introduce an amine-support system designed achieve efficient stable capture. Through atom-level design, each polyethyleneimine (PEI) molecule precisely impregnated into the cage-like pore of MIL–101(Cr), forming composites via strong coordination with...
Adsorbents for CO<sub>2</sub> captured with nano silica as support were synthesized by impregnating polyethyleneimine (PEI) into silica.
After carbonization and activation, pine cone shell-based activated carbons were used to adsorb CO<sub>2</sub>, presenting a good adsorption performance.
Amine–silica hybrid materials have been investigated extensively in terms of their suitability for postcombustion CO2 capture. However, research on how the silica types affects synthesis and performance amine–silica is scarce. In this study, four commonly used representative including precipitated silica, fumed MCM-41, gel are to synthesize a series comparable by grafting silane onto them. We undertake porosity analysis plain determined adsorption materials. The results suggest that superior...
Calcium silicate hydrate (CSH) is a potential new material for effective heavy metal adsorption, but the high manufacturing costs and difficult reusability have restricted its large-scale application. Herein, we report green facile strategy to prepare amorphous hierarchically structured CSH-based nanocomposites from steel slag removal. The obtained flowerlike materials showed fast adsorption rates superior capacities all employed ions (Cu(II), Pb(II), Zn(II)), with maximum of approximately...
Capturing anthropogenic CO2 in a cost-effective and highly efficient manner is one of the most challenging issues faced by scientists today. Herein, we report novel structure-reforming approach to convert steel slag, cheap, abundant, nontoxic calcium-rich industrial waste, as only feedstock into superior CaO-based, self-stabilizing sorbents. The capture capacity all slag-derived sorbents was improved more than 10-fold compared raw with maximum uptake achieving at 0.50 gCO2 gsorbent(-1)....
High-temperature sorption of CO2 via calcium looping has wide applications in postcombustion carbon capture, sorption-enhanced hydrogen production, and inherent energy storage. However, fast deactivations CaO sorbents low uptake the carbonation stage are major drawbacks this technology. For first time, we developed a green approach through reuse nanosilica derived from coal fly ash (CFA) to enhance both cyclic uptakes kinetics sorbents. The as-synthesized nanosilica-supported sorbent showed...
Solid amine adsorbents are among the most promising CO2 adsorption technologies for biogas upgrading due to their high selectivity toward CO2, low energy consumption, and easy regeneration. However, in cases, these undergo severe chemical inactivation urea formation when regenerated under a realistic atmosphere. Herein, we demonstrated facile efficient synthesis route, involving of nano-Al2O3 support derived from coal fly ash with flow as precipitant preparation polyethylenimine...
A new surface-ion-imprinted amino-functionalized silica gel sorbent was prepared by the surface imprinting technique with As(V) as template, 3-(2-aminoethylamino)propyltrimethoxysilane functional monomer, support, and epichlorohydrin cross-linking agent characterized FTIR, SEM, nitrogen adsorption, static adsorption–desorption experiment method. The results showed that maximum adsorption capacity of imprinted 16.1 mg·g–1, equilibrium could be reached in 20 min, there no influence pH values...
