Study of enantioselective metolachlor adsorption by activated carbons

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 ...

Study the Static Adsorption/Desorption of Formaldehyde on Activated Carbons

Hydrogen Storage by Adsorption onto Different Activated Carbons

The objective of this work was to evaluate the hydrogen storage capacities of various activated carbon materials in form of granules, powders, fibers and clothes under cryogenic and ambient temperature conditions (77K 293K), at pressures up to 30Bar. The experimental data were analyzed for carbon samples covering a wide range of BET surfaces and microporous volumes. At 293K, the storage capacit...

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...
