Wall-to-liquid mass transfer in fluidized beds and vertical transport of inert particles / Prenos mase zid-fluid u fluidizovanim slojevima i pri vertikalnom transportu inertnih čestica
(Serbian Chemical Society, Belgrade, 2007)
Mass transfer coefficients in single phase flow, liquid fluidized beds and vertical hydraulic transport of spherical inert particles were studied experimentally using 40 mm and 25.4 mm diameter columns. The mass transfer ...
Vapor-liquid equilibria of triglycerides-methanol mixtures and their influence on the biodiesel synthesis under supercritical conditions of methanol / Ravnoteža para-tečnost za sistem trigliceridi-metanol i njen uticaj na kinetiku sinteze biodizela pod uslovima natkritičnog metanola
(Serbian Chemical Society, Belgrade, 2007)
The non-catalytic synthesis of biodiesel (fatty acids methyl esters) from triglycerides and methanol proceeds at elevated pressures above 100 bar and temperatures above 523 K. Kinetic investigations of the system revealed ...

A kinetic study of the thermal degradation of cetyltrimethylammonium bromide inside the mesoporous SBA-3 molecular sieve / Kinetičko izučavanje termičkog razlaganja cetiltrimetilamonijum−bromida unutar mezoporoznog molekulskog sita SBA-3
(Serbian Chemical Society, Belgrade, 2007)
The thermal degradation of cetyltrimethylammonium bromide (CTMAB) inside the mesoporous SBA-3 was studied under non-isothermal conditions. There are two distinct and complex kinetic processes which partly overlap, each ...
An experimental study of the partial oxidation of ethane to ethylene in a shallow fluidized bed reactor / Eksperimentalno ispitivanje parcijalne oksidacije etana do etilena u reaktoru sa plitkim fludizovanim slojem
(Serbian Chemical Society, Belgrade, 2007)
The partial catalytic oxidation of ethane to ethylene was investigated experimentally in a shallow fluidized bed. The performances of two catalyst types, pure γ-Al2O3 and V2O5/γ-Al2O3 particles 1.8 mm in diameter, were ...
Effect of temperature on the electrodeposition of disperse copper deposits / Uticaj temperature na elektrohemijsko taloženje disperznih taloga bakra
(Serbian Chemical Society, 2007)
The effect of temperature on the electrodeposition of copper at overpotentials belonging to the plateau of the limiting diffusion current density and higher was examined by the determination of the average current efficiency ...
A linear solvation energy relationship study for the reactivity of 2-substituted cyclohex-1-enecarboxylic and 2-substituted benzoic acids with diazodiphenylmethane in aprotic and protic solvents / Proučavanje reaktivnosti 2-supstituisanih cikloheks-1- -enkarboksilnih i 2-supstituisanih benzoevih kiselina u aprotičnim i protičnim rastvaračima pomoću linearne korelacije solvatacionih energija
(Serbian Chemical Society, Belgrade, 2007)
The rate constants for the reaction of 2-substituted cyclohex-1-enecarboxylic acids and the corresponding 2-substituted benzoic acids with diazodiphenylmethane were determined in various aprotic solvents at 30 ºC. In order ...
