A Step Forward in Understanding the Hydrogen Adsorption and Compression on Activated Carbons

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...

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...

Hydrogen Adsorption on Activated Carbon

The adsorption of hydrogen on carbon nanotubes and activated carbons has generated considerable interest in relation to hydrogen storage for fuel cells applications[1-3]. However, the widespread use of hydrogen as a fuel is limited by the lack of a convenient and cost-effective method of hydrogen storage. Adsorption of supercritical hydrogen is limited by the low interaction energy between hydr...
