beta-Carotene removal from soybean oil with smectite clay using central composite design
(Maik Nauka/Interperiodica/Springer, New York, 2009)
In this study removal of beta-carotene from soybean oil by adsorption on acid activated smectite clay from Serbia was investigated and a factorial 2(3) experimental design was applied. The effects of relevant factors, such ...
Structural and textural properties of Al,Fe-pillared clay catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Metal oxide pillared interlayered clays (PILCs) represent a new class of materials that have found a wide range of potential applications including catalytic oxidative degradation of organic pollutants in water. Al,Fe-pillared ...
Oxidation of formic acid on platinum surfaces decorated with cobalt(III) macrocyclic complexes
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Platinum electrode decorated with three different mixed-ligand cobalt(III) complexes of the general formula [Co(Rdtc)cyclam](ClO4)(2) [cyclam = 1,4,8,11-tetraazacyclotetradecane, Rdtc(-) = morpholine-(Morphdtc), ...
The state of nickel in the silver modified NiMg/SiO2 vegetable oil hydrogenation catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Two series of silver modified Ni-Mg materials were synthesized by precipitation-deposition on SiO2 support derived from two silica sources: diatomite activated at 800°C (Series a; Mg/Ni = 0.1 and SiO 2/Ni = 1.07) and ...
A study of the dispersity of iron oxide and iron oxide-noble metal (Me=Pd, Pt) supported systems
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Samples of one-(Fe) and two-component (Fe-Pd and Fe-Pt) catalysts were prepared by incipient wetness impregnation of four different supports: TiO2 (anatase), gamma-Al2O3, activated carbon, and diatomite. The chosen synthesis ...
Thin layer of Ni-modified 13X zeolite on glassy carbon support as an electrode material in aqueous solutions
(Maik Nauka/Interperiodica/Springer, New York, 2007)
A new type of an electrode material, zeolite modified by the incorporation of Ni or NiO clusters into its cavities, was synthesized by multiple impregnation of zeolite 13X with a Ni-acetylacetonate solution followed by ...
Chemical and radiochemical characterization of depleted uranium in contaminated soils
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The main results of chemical and radiochemical characterization and fractionation of depleted uranium in soils contaminated during the Balkan conflict in 1999 are presented in the paper. Alpha-spectrometric analysis of ...
Removal of volatile organic compounds from activated carbon by thermal Desorption and catalytic combustion
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The thermal desorption of saturated activated carbon discharged from an industrial adsorber and catalytic oxidation of desorbed products over a Pt/Al2O3 catalyst were investigated. The activated carbon is almost completely ...
Characterization of double oxide system Cu-Cr-O supported on gamma-Al2O3
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Series of alumina supported chromium-copper catalysts were prepared by co-impregnation method. The samples were characterized by X-ray diffraction, X-ray photoelectron spectroscopy and UV-visible diffuse reflectance ...
Mass transfer and fluid flow visualization in packed and fluidized beds by the adsorption method
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Mass transfer coefficient (j D ) between fluid and column wall in liquid packed and fluidized beds of spherical inert particle has been studied experimentally using adsorption method. Experiments were conducted in column ...
