In the present study, adsorption of Co(tsPc)-4 using γ-Alumina was investigated. γ-Alumina was prepared by gel combustion method. The XRD pattern revealed that the synthesized γ-Alumina is amorphous and SEM image showed its nanosize scale while BET surface area about 501 m2/g and pore size of 7 nm implies highly porous surface which is a characteristic property of a high-quality adsorbent. In t...

To decrease the operating cost of flue gas purification technologies based on carbon-based materials, the adsorption and regeneration performance of low-price semi-coke and activated coke were compared for SO2 and NO removal in a simulated flue gas. The functional groups of the two adsorbents before and after regeneration were characterized by a Fourier transform infrared (FTIR) spectrometer, a...

In a simulated moving bed, the regeneration is accomplished by introduction of third species, desorbent, which later recovered two downstream separations. As such, choice proper adsorbent/desorbent pair critical to ensure effectiveness SMB process. While this can be done comparing separation region for each system, computational effort required extremely high. By developing parameter that uses ...

Abstract The paper presents the results on rapid production of H 2 from CH 4 by its direct decomposition in a plasma-catalytic mode stimulated microwave irradiation (MWI) at 600°C. Methane was passed through bed iron-containing carbon adsorbent obtained gas coal characterized large dielectric loss tangent. Under MWI, intense breakdown effects with plasma generation appear surface iron–carbon sy...

Abstract:  In this study adiffusion based mathematical model was developed to compare the performance of amine-grafted adsorbents with that of 13X zeolite in a fixed-bed adsorption tower which is used to capture CO2 from both humid and dry nitrogen stream under industrial conditions. The results show that the performance of amine-grafted adsorbent and 13X zeolite is almost the same in the dry ...

In this research paper, chemically activated Thuja Occidentalis leaves carbon (CATLC) is used as an adsorbent for the removal of calcium (Ca2+) ion from aqueous solution. CATLC is prepared and characterized by FTIR, SEM and EDX. The impact of pH, adsorbent dosage, contact period and initial concentration of Ca2+ on the adsorption performance of CATLC for Ca2+ removal are examined by batch studi...

Facing the global freshwater resource crisis, using solar energy to produce fresh water resources in an environmentally friendly way, sorption-based atmospheric harvesting driven by technology has attracted increasingly more attention. In current research, adsorbent MOF-801 advantages of a high adsorption capacity and is suitable for fields with wide range humidity. However, strong interaction ...

in the present study seven synthetic polymers were used as adsorbents for the removal of cd(ii) from aqueous solution. the equilibrium studies were systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and ph of the aqueous solution. the analyzing system was an atomic absorption spectrometer (perkin-analyst 100). it was...

Adsorption process has proven its efficiency in the abatement of pharmaceuticals liquid media, even if large volumes wastewater need to be treated. Nevertheless, exhausted adsorbent regeneration is economically and environmentally necessary. For this reason, recent studies are aimed at finding new methods regeneration. In study, an on-site adsorption-regeneration method was assessed. Initially,...

This work investigates the effects of several parameters on coefficient performance (COP) and specific heating power (SHP) a coated-tube adsorber for adsorption heat pumps (AHP) suitable water (space and/or domestic heating). The COP SHP are obtained based physical models that have already been proven to adequately describe this type adsorber. Several tested, namely, regeneration, condenser eva...
