Simulation of blast furnace operation during the substitution of coke and pulverized coal with granulated waste plastic / Simulacija rada visoke peći prilikom supstitucije koksa i sprašenog uglja granulisanom otpadnom plastikom
(Savez inženjera i tehničara Srbije, Beograd, 2014)
The possibility of using the waste plastic as reducing agent in blast furnace for obtaining pig iron is in focus for the past couple year. The simulation of blast furnace process in BFC software has been performed in order ...
Effect of tracers molecular weight on the release process from alginate microbeads / Uticaj molekulske mase trejserskih indikatora na kontrolisano otpuštanje iz alginatnih mikročestica
(Savez inženjera i tehničara Srbije, Beograd, 2015)
The aim of this paper is to obtain microbeads of natural polymers such as alginate and chitosan. These microbeads were used as potential carriers for the active ingredients so that in this study the diffusion of various ...
Competitive sorption of silver, zinc and copper ions on different types of sorbent / Komparativna sorpcija jona teških metala na različitim tipovima sorbenata
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2015)
In this master thesis the sorption of heavy metals on activated carbon and zeolite was analyzed. The chosen heavy metals (Ag+, Cu2+, Zn2+) have been analyzed separately and as a mixture in order to check their sorption ...
Analysis of catalyst wetting efficiency influence on performances of industrial TBR for hydro desulfurization and hydro de aromatization reactions / Analiza uticaja ovlaženosti katalizatora u industrijskom TBR reaktoru na reakcije hidrodesulfurizacije i hidrodearomatizacije
(Savez inženjera i tehničara Srbije, Beograd, 2015)
Many industrial scale trickle bed reactors (TBR) operate at lower liquid superficial velocities ( lt 0.5 cm/s) at which the catalyst particle are not completely wetted. This phenomenon of incomplete wetting has therefore ...
