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 ...
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 ...
Temperature influence on the malonic acid decomposition in the Belousov-Zhabotinsky reaction
(Maik Nauka/Interperiodica/Springer, New York, 2009)
The kinetic investigations of the malonic acid decomposition (8.00 x 10(-3) mol dm(-3) a parts per thousand currency sign [CH(2)(COOH)(2)](0) a parts per thousand currency sign 4.30 x 10(-2) mol dm(-3)) in the Belousov-Zhabotinsky ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
