Separation of nitrogen from a gaseous mixture is required for many industrial processes. In this study, the adsorption of nitrogen on zeolite 4A was investigated in terms of different adsorption isotherm models and kinetics. An increase in the initial pressure from 1 to 9 bar increases the amount of adsorbed nitrogen from 6.730 to 376.030 mg/(g adsorbent). The amount of adsorbed nitrogen increa...

The question we pose in this study is to what extent the ranking of metal organic frameworks (MOFs) for pressure swing adsorption-based carbon capture depends on choice commonly available forcefields.

Activated carbon honeycomb-monoliths with different textural properties were prepared by chemical activation of African palm shells with H(3)PO(4), ZnCl(2) and CaCl(2) aqueous solutions of various concentrations. The adsorbents obtained were characterized by N(2) adsorption at 77 K, and their carbon dioxide adsorption capacities were measured at 273 K and 1 Bar in volumetric adsorption equipmen...

the modeling of kinetic and isotherm curves acquired in adsorption of polycyclic aromatic hydrocarbons (pahs) as a model compound (phenanthrene) on activated carbons in the organic solvent. all the runs were carried out in a batch system at atmospheric pressure, process temperature of 24±2°c, and using the 100 ml phenanthrene in cyclohexan. this experimental work was mainly focused on the study...

Aluminophosphate monoliths with high CO 2-over-N 2 selectivity and CO 2 capture capacity. Access to the published version may require subscription. a Monoliths of microporous aluminophosphates (AlPO 4-17 and AlPO 4-53) were structured by binder-free pulsed current processing. Such monoliths could be important for carbon capture from flue gas. The AlPO 4-17 and AlPO 4-53 monoliths exhibited a te...

Amine-containing adsorbents have been extensively investigated for post-combustion carbon dioxide capture due to their ability to chemisorb low-concentration carbon dioxide from a wet flue gas. However, earlier studies have focused primarily on the carbon dioxide uptake of adsorbents, and have not demonstrated effective adsorbent regeneration and long-term stability under such conditions. Here,...
