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 ...
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 ...
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), ...
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 ...
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 ...
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 ...
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 ...
Large deviation spectra of chaotic time series from Bray-Liebhafsky reaction
(Maik Nauka/Interperiodica/Springer, New York, 2009)
We applied multifractal analysis on time series obtained by deterministic simulation of the Bray-Liebhafsky oscillatory reaction. Large deviation spectrum was used to represent multifractal properties of the attractor. We ...
Activity of polymer supported cobalt catalyst in the Bray-Liebhafsky oscillator
(Maik Nauka/Interperiodica/Springer, New York, 2009)
The infuence of poly-4-vinylpyridine-co-divinylbenzene-Co2+ catalyst on the Bray-Liebhafsky (BL) oscillator used as the matrix for establishing catalyst's activity was analyzed. The addition of the catalyst do not change ...
Temperature dependence of catalytic cyclohexane partial oxidation in a polytetrafluoroethylene reactor
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Polymer-supported Co(II) catalyst was prepared and its activity and selectivity in the partial oxidation of cyclohexane was determined at several temperatures in a polytetrafluoroethylene reactor ( PTFE). The catalyst was ...
