Comparison of uniform and non-uniform pressure approaches used to analyze an adsorption process in a closed type adsorbent bed
(Springer, 2013)
Heat and mass transfer in an annular adsorbent bed filled with silica gel particles is numerically analyzed by uniform and non-uniform pressure approaches. The study is performed for silica gel-water pair, particle radius ...
Investigation of structural properties of clinoptilolite rich zeolites in simulated digestion conditions and their cytotoxicity against Caco-2 cells in vitro
(Springer, 2013-04)
The use of the clinoptilolite rich natural zeolites in biomedical applications such as in anticancer therapy, drug or drug support systems and as nutritive supplement is highly dependent on their behavior in digestive ...
The use of metal piece additives to enhance heat transfer rate through an unconsolidated adsorbent bed
(Elsevier, 2010-06)
The effects of metal piece additives on effective thermal conductivity and diffusivity of an unconsolidated adsorbent bed in which adsorbent is silica gel were investigated. The metal piece additives were copper, brass, ...
Supercritical carbon dioxide drying of methanol-Zinc borate mixtures
(American Chemical Society, 2009-07)
Supercritical carbon dioxide (CO 2) drying of zinc borate species was investigated to evaluate possible chemical alterations in the product during the drying. Methanol-wetted zinc borates produced either from borax decahydrate ...
Clinoptilolite-rich mineral as a novel carrier for the active constituents present in Ginkgo biloba leaf extract
(Elsevier, 2008-06)
The possible use of clinoptilolite-rich mineral as a novel carrier for the active constituents present in Ginkgo biloba leaf extract solutions was investigated. The flavonoid aglycone constituents were found to be selectively ...
Heat and mass transfer in the adsorbent bed of an adsorption heat pump
(Taylor & Francis, 2011-10)
The heat and mass transfer equations governing an adsorbent bed in an adsorption heat p mp and the mass balance equation for the adsorbent particles in the adsorbent bed were solved numerically to simulate the cycle of a ...
A dimensionless analysis of heat and mass transport in an adsorber with thin fins; uniform pressure approach
(Elsevier, 2011-07)
A numerical study on heat and mass transfer in an annular adsorbent bed assisted with radial fins for an isobaric adsorption process is performed. A uniform pressure approach is employed to determine the changes of temperature ...
Synthesis of zinc borate by inverse emulsion technique for lubrication
(Springer, 2011-05)
Lubricating oil additives based on boron compounds are promising materials for lubrication due to their tribological advantages such as antiwear efficiency, good film strength, and high temperature resistance. This article ...
Characterization of pure and silver exchanged natural zeolite filled polypropylene composite films
(Elsevier, 2005-10)
In the present study, untreated and silver exchanged natural zeolite-polypropylene (PP) composites were prepared and characterized by means of different techniques (TGA, DSC, mechanical tests, density measurements, optical ...
Synergistic effect of natural zeolites on flame retardant additives
(Elsevier, 2005-09)
The thermal degradation and flammability of intumescent fire-retardant polypropylene matrix composites consisting of ammonium polyphosphate (APP) as an acid source and blowing agent, pentaerythritol (PER) as a carbonisation ...
