Porous glycidyl methacrylate-bentonite composite
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Crosslinked macroporous copolymer of glycidyl methacrylate and ethylene glycol dimethacrylate (CP) and copolymer composite with acid modified clay (CP-S-A) were prepared by radical suspension copolymerization and functionalized ...
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 ...
Kinetics and mechanism of structural transformations of 2-(5-ethoxycarbonylmethyl-4-oxothiazolidin-2-ylidene)-N-(2-phenylethyl)-ethanamide during heating
(Maik Nauka/Interperiodica/Springer, New York, 2011)
The kinetics and mechanism of the structural transformation of 2-(5-ethoxycarbonylmethyl-4-oxothiazolidin-2-ylidene)-N-(2-phenylethyl)-ethanamide in non-isothermal conditions were studied by using isoconversion as well as ...
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 ...
Enhanced activity in ethanol oxidation of Pt3Sn electrocatalysts synthesized by microwave irradiation
(Maik Nauka/Interperiodica/Springer, New York, 2011)
High surface area carbon supported Pt and Pt3Sn catalysts were synthesized by microwave irradiation and investigated in the ethanol electro-oxidation reaction. The catalysts were obtained using a modified polyol method in ...
Perlite as a potential support for nickel catalyst in the process of sunflower oil hydrogenation
(Maik Nauka/Interperiodica/Springer, New York, 2015)
Investigation was conducted in order to elucidate the possibility of using perlite as support for preparation of nickel based precursor catalyst, potentially applicable in vegetable oil hydrogenation process. On three ...
Effect of the support and the reduction temperature on the formation of metallic nickel phase in Ni/silica gel precursors of vegetable oil hydrogenation catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Ni/SiO(2) materials with identical composition (SiO(2)/Ni = 1.0) have been synthesized by precipitation of Ni(NO(3))(2) center dot 6H(2)O solution with Na(2)CO(3) solution on the silica gel, obtained at three different pH ...
Influence of most important radicals on the numerically simulated belousov-zhabotinsky oscillatory reaction under batch conditions
(Maik Nauka/Interperiodica/Springer, New York, 2011)
In the already proposed model of the Belousov-Zhabotinsky reaction with the Br(2)O species as intermediate one, the reactions with malonyl (MA(center dot)), bromomalonyl (BrMA(center dot)) and tartronyl (TA(center dot)) ...
Temperature influence on the malonic acid decomposition in the Belousov-Zhabotinsky reaction
