(Institut bezbednosti, Beograd, 2004)
N-(4-Methylphenyl)-2-phenylacetamide and N-(4-methoxyphenyl)-2-phenylacetamide were alkylated with benzyl chloride in the presence of powdered KOH in various solvents as well as in the presence of phase-transfer catalysts, ...
Biodiesel II: A new concept of biodiesel production - transesterification with supercritical methanol / Biodizel II - novi koncept dobijanja biodizela - transesterifikacija u natkritičnim uslovima metanoia
(Association of Chemical Engineers of Serbia, 2004)
Biodiesel is defined as a fuel that might be used as a pure biofuel or at high concentration in mineral oil derivatives, in accordance with specific quality standards for transport applications. The main raw material used ...
Mass transfer from the wall of a column to the fluid in a fluidized bed of inert spherical particles / Prenos mase zid-fluid u partikulativno fluidizovanim slojevima
(Association of Chemical Engineers of Serbia, 2004)
Mass transfer in fluidized beds is an important operation for separation processes. Two effects can be achieved by using fluidized beds in mass transfer processes increasing interface area and relative movement between the ...

Energy and economy savings in the process of methanol synthesis unsig Pinch technology / Energetsko i ekonomsko poboljšanje procesa sinteze metanola primenom Pinch tehnologije
(Serbian Chemical Society, Belgrade, 2004)
A heat exchanger network (HEN) for the process of methanol synthesis has been studied by pinch design analysis. Great economic and energy savings were realized by the pinch analysis in comparison to the existing plant. ...
Dynamic holdup in a countercurrent gas - flowing solids - packed bed contactors / Dinamički sadržaj pokretne čvrste faze u suprotnostrujnim kontaktorima gas - čvrsto - čvrsto
(Serbian Chemical Society, Belgrade, 2004)
Equations for the prediction of the holdup of dynamic solids in countercurrent gas – flowing solids – packed bed contactors are presented in this paper. The correlations do not require the use of parameters that need to ...
The structure directing role of 1,3-diaminopropane in the hydrothermal synthesis of iron(III) phosphate
(Srpsko hemijsko društvo, Beograd, 2004)
13-Diaminopropane (DAP) was used as a structure-directing agent for the hydrothermal synthesis of an organically templated iron phosphate. During crystallization at 180 degreesC, iron phosphate (FePO-DAP) with a layered ...
Sorpciona svojstva vune / Sorption properties of wool
(Savez hemijskih inženjera, Beograd, 2004)
Rigorozni ekološki propisi, posebno u visoko razvijenim zemljama, nametnuli su zahteve za prečišćavanjem otpadnih industrijskih voda i potrebu za efikasnim uklanjanjem naftnih mrlja nakon izlivanja nafte i njenih derivata ...
