Distillery wastes to lactic acid: Bio refinery approach / Destilerijski otpad za proizvodnju mlečne kiseline i stočne hrane - biorafinerijski pristup
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2015)
The cost of distillery wastewater treatment is an important issue in overall economy of bioethanol production. Besides traditional utilization of distillery wastewater or stillage in animal nutrition, its chemical ...
Sepiolite from Serbian deposits as an industrial mineral / Sepiolit iz ležišta u Srbiji kao industrijski mineral
(Savez inženjera i tehničara Srbije, Beograd, 2015)
Long-termed geological exploration of sepiolite in Serbia has proved that there exist two structuralmorphological types of sepiolite deposits: the vein type - in ultrabasic rocks, associated with vein magnesite deposits ...
Techno-economic optimization of energy supply of a livestock farm / Tehno-ekonomska optimizacija snabdevanja energijom farmi stoke
(Univerzitet u Nišu, Niš, 2015)
Livestock farming is a significant part of agricultural market in Serbia. However, a descending trend of livestock species has been recorded recently, despite its potential for meat export. Application of new technologies ...
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 ...
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 ...
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 ...
Bioindicators as a tool for environmental pollution analysis / Bioindikatori kao sredstvo za analizu zagađenosti životne sredine
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2015)
The interest in using bioindicators as monitoring tools to assess environmental pollution with toxic metals continually increasing. Heavy metals arise from natural sources and human activities, and once released in the ...
Optimization of chitosan gel preparation for supercritical impregnation of thymol / Uticaj pripreme hitozan gelova na natkritičnu impregnaciju sa timolom
(Savez inženjera i tehničara Srbije, Beograd, 2015)
The impregnation of differently prepared chitosan gels with thymol using supercritical carbon dioxide (scCO2) was studied in order to obtain new materials with added value without the use of organic solvents. The optimum ...
Formic acid electrooxidation on carbon supported platinum catalyst with preferential plane orientation / Oksidacija mravlje kiseline na platinskim katalizatorima na ugljeničnom nosaču sa preferencijalno orijentisanim ravnima
(Savez inženjera i tehničara Srbije, Beograd, 2015)
Pt-based nanocatalysts supported on Vulcan XC-72R carbon, were prepared by water-in-oil microemulsion method, with addition of various amounts of HCl in the water phase. Polyethileneglycoldodecylether (BRIJ 30) was used ...
