Thermally Assisted Simulated Moving Bed Systems
Adsorption - Tập 11 - Trang 579-584 - 2005
The principles of simulated moving bed (SMB) and thermal swing adsorption (TSA) are combined to develop a traveling wave mode, thermally assisted SMB. The four-zone, thermal SMB and the corresponding one-column, thermal Analog to the SMB are studied for separating binary systems with linear isotherms. Design parameters and operating conditions are determined using the local equilibrium theory and ...... hiện toàn bộ
Adsorption of naphthalene and pyrene from isooctane solutions on commercial activated carbons
Adsorption - Tập 17 - Trang 937-947 - 2011
The adsorption of naphthalene and pyrene on two different types of commercial activated carbons was studied by batch and column experiments. Adsorption equilibrium was measured at three different temperatures. Heats of adsorption were estimated from the equilibrium results and compared to other previous reports. From the column experiments, using parameters obtained from the batch experiments and ...... hiện toàn bộ

Adsorption of Sulfur Dioxide from Pseudo Binary Mixtures on Hydrophobic Zeolites: Modeling of the Breakthrough Curves
Adsorption - Tập 8 - Trang 279-289 - 2002
The adsorption of SO2 from pseudo binary mixtures with water and CO2 on hydrophobic zeolites (MFI and MOR type) was investigated using the breakthrough curve method. The SO2 and water breakthrough curves were compared with theoretical ones based on an axially dispersed plug flow through the column and the linear driving force rate equation. In addition, different semi-predictive multi-component eq...... hiện toàn bộ
Adsorption Behaviour of 134Cs and 22Na Ions on Tin and Titanium Ferrocyanides
Adsorption - Tập 10 - Trang 237-244 - 2004
Tin and titanium ferrocyanides were studied as adsorbents for alkali metal ions, viz., 134Cs and 22Na, which represent radioactive wastes. The ferrocyanides were prepared in granular form. The tin version contained 11.2% water, while the titanium version contained 17.7% water. The exchange capacities for Cs+ and Na+ in the hydrated tin version were about 1.5 and 0.7 meq/g, respectively, while thos...... hiện toàn bộ
Development and optimization of magnetic technologies based processes for removal of some toxic heavy metals
Adsorption - Tập 13 - Trang 95-104 - 2007
In the developing countries where the cost is often a decisive factor, extensive studies were undertaken to test the most effective factors on the preparation, optimization and validation of the magnetic particles (or, more accurately, magnetizable particles) for removal of heavy metals from wastewaters. The objective of the proposed work was focused to provide promising solid-phase materials, wh...... hiện toàn bộ
Synthesis and Adsorption Characteristics of Nanoporous Graphite-Derived Carbon-Silica Composites
Adsorption - Tập 11 - Trang 725-730 - 2005
A novel nanoporous C/SiO2 composite was synthesized using graphite precursor by a soft chemical method and its adsorption properties were characterized by nonane, water, and nitrogen adsorption. It was found that only one part of micropores can strongly confine nonane molecules, indicating a wide micropore size distribution. Water adsorption leads to disappearance of one part of micropores, possib...... hiện toàn bộ
Developments and structures of mesopores in alkaline-treated ZSM-5 zeolites
Adsorption - Tập 12 - Trang 309-316 - 2006
ZSM-5 zeolites with SiO2/Al2O3 molar ratio of 24 were treated in 0.05 M aqueous sodium hydroxide solution at 325 K in different periods. The samples were characterized by means of nitrogen adsorption at 77 K, field emission scanning electron microscopy, X-ray diffractometry, and Fourier transform infrared spectroscopy. Analysis of the experimental results showed that the alkaline treatment periods...... hiện toàn bộ
Equilibrium isotherms and isosteric heat for CO2 adsorption on nanoporous carbons from polymers
Adsorption - Tập 22 - Trang 581-588 - 2015
Four nanoporous carbons obtained from different polymers: polypyrrole, polyvinylidene fluoride, sulfonated styrene–divinylbenzene resin, and phenol–formaldehyde resin, were investigated as potential adsorbents for carbon dioxide. CO2 adsorption isotherms measured at eight temperatures between 0 and 60 °C were used to study adsorption properties of these polymer-derived carbons, especially CO2 upta...... hiện toàn bộ
