Tailoring Activated Carbons for Efficient Downstream Processing: Selective Liquid‐Phase Adsorption of Lysine

CO2 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 ...

Understanding Phenol Adsorption Mechanisms on Activated Carbons

The interactions between phenol molecules and activated carbons were investigated in order to understand the adsorption mechanism of this aromatic compound. A series of activated carbons with varied chemical composition but similar porous features were synthesized and submitted to phenol exposure from aqueous phase, followed by thermogravimetric analysis and identification of the desorbed speci...

Effect of porous texture on hydrogen adsorption in activated carbons

Physisorption-based hydrogen (H 2) storage in microporous carbons has a trade-off between adsorption capacity and adsorption enthalpy [5]. Conceptually, this problem is best illustrated in terms of the ideal slit pore formed from two parallel, semi-infinite graphite slabs. Packing density is maximized when the pore width is several times larger than the diameter of the H 2 molecule, since it pe...

Study the Static Adsorption/Desorption of Formaldehyde on Activated Carbons

2001: Characterization of Activated Carbons Using Liquid Phase Adsorption

The pore size distribution is the most important aspect in characterization of structural heterogeneity of porous materials. Different methods have been developed and applied for the characterization of this property, and the most often used is gas adsorption [1,2], while liquid phase adsorption is seldom used [3]. A modification of the Dubinin-Radushkevich pore filling by incorporation of the ...
