Application of lignocellulolytic fungi for bioethanol production from renewable biomass / Primena gljiva koje razgrađuju lignocelulozu za proizvodnju bioetanola iz obnovljive biomase
(Association of Chemical Engineers of Serbia, 2015)
Pretreatment is a necessary step in the process of conversion of lignocellulosic biomass to ethanol; by changing the structure of lignocellulose, enhances enzymatic hydrolysis, but often it consumes large amounts of energy ...
A new procedure for the treatment of an industrial waste containing flotation reagents / Novi postupak prerade industrijskog otpada koji sadrži flotoreagense na bazi ksantata
(Association of Chemical Engineers of Serbia, 2014)
Flotation reagents can be transformed to industrial waste if they are stored for a long period of time. Also, if synthesis or drying process is not performed under defined conditions in industrial plants, which produce ...
Iron-chromium-carbon-vanadium white cast irons: The microstructure and properties / Železo-hrom-ugljenik-vanadijum bela livena gvozđa - mikrostruktura i svojstva
(Association of Chemical Engineers of Serbia, 2014)
The as-cast microstructure of Fe-Cr-C-V white irons consists of M7C3 and vanadium rich M6C5 carbides in austenitic matrix. Vanadium changed the microstructure parameters of phase present in the structure of these alloys, ...
Removal of magnesium in spring water using the natural zeolite in a continuous flow system / Uklanjanje magnezijuma iz izvorske vode pomoću prirodnog zeolita u protočnom sistemu
(Association of Chemical Engineers of Serbia, 2014)
The aim of this work is an investigation of the possible application of Serbian natural zeolitic tuff ('Igroš Vidojević' deposit, Brus, Serbia) for improvement of the spring water quality. The concentration of magnesium ...
Influence of yarn folding on uv protection properties of hemp knitted fabrics
(Savez hemijskih inženjera, Beograd, 2016)
In the last years the media have highlighted the damage of the ozone layer and the resulting increase of ultraviolet radiation (UVR) reaching the Earth's surface. Prolonged and repeated, both occupational and recreational, ...
Fenton process in dispersed systems for industrial wastewater treatment
(Savez hemijskih inženjera, Beograd, 2019)
Industrial wastewater contains recalcitrant organic compounds with a very complex chemical structure, built of molecules with long chains of carbon atoms and attached different functional groups. Chemical or biological ...
Polypyrrole vertical bar zinc supercapattery with the aqueous electrolyte
(Savez hemijskih inženjera, Beograd, 2017)
Polypyrrole (PPY) electrode was obtained by electrochemical oxidative polymerization of pyrrole on graphite electrode from aqueous electrolyte containing 0.1 mol dm(-3) pyrrole monomer and 1.0 mol dm(-3) HCl. Polymerization ...
Calculation and optimization of the copper (II) sulphate monohydrate from copper (II) sulphate pentahydrate production process in a fluidized bed dryer / Proračun i optimizacija procesa proizvodnje bakar(II)-sulfat-monohidrata iz bakar(II)-sulfat-pentahidrata u sušnicama sa fluidizovanim slojem
(Association of Chemical Engineers of Serbia, 2015)
In this paper the process of the copper (II) sulphate monohydrate from copper (II) sulphate pentahydrate (also known as a Blue vitriol or Bluestone) production was analyzed. Copper (II) sulphate pentahydrate is one of the ...
