Whether integrating refining and petrochemical business can provide opportunities for development of petrochemical industry in Serbia / Da li integrisanje rafinerijskog i petrohemijskog biznisa pruža mogućnost za razvoj petrohemijske industrije u Srbiji
(Serbia : Association of Chemists and Chemical Engineers of Serbia, 2016)
Since the beginning of 90s of last century both the petroleum industry and petrochemical industry have operated in difficult circumstances. In particularly, margins of petroleum and petrochemical industry were exacerbated ...
Investigation of the morphology and surface properties of crosslinked poly(urethane-ester-siloxane)s / Ispitivanje morfologije i površinskih svojstava umreženih poli(uretan-estar-siloksana)
(Association of Chemical Engineers of Serbia, 2012)
Two series of crosslinked poly(urethane-ester-siloxane)s were synthesized from α,ω-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS- -EO), 4,4'-methylenediphenyl diisocyanate and Boltorn® hyperbranched ...
Functionalized macroporous copolymer of glycidyl methacrylate: The type of ligand and porosity parameters influence on Cu(II) ion sorption from aqueous solutions / Funkcionalizovani makroporozni kopolimer na bazi glicidilmetakrilata - uticaj liganda i parametara poroznosti na sorpciju Cu(II) jona iz vodenih rastvora
(Association of Chemical Engineers of Serbia, 2009)
The removal of heavy metals from hydro-metallurgical and other industries' wastewaters, their safe storage and possible recovery from waste- water streams is one of the greater ecological problems of modern society. ...
Evaluation of water, sucrose and minerals effective diffusivities during osmotic treatment of pork in sugar beet molasses / Prividni koeficijenti difuzije vode, saharoze i minerala pri osmotskom tretmanu svinjskog mesa u melasi šećerne repe
(Association of Chemical Engineers of Serbia, 2015)
Effective diffusivities of water, sucrose and minerals in osmotic treatment of pork cubes (M. triceps brachii) were calculated using Response Surface Methodology (RSM), with respect to temperature (20, 35 and 50°C) and ...
Removal of ethylene oxide from waste gases by absorption / Uklanjanje etilen-oksida iz otpadnih gasova postupkom apsorpcije
(Association of Chemical Engineers of Serbia, 2011)
Ethylene oxide (EtO) is an organic compound, which is used as a starting material in the production of polymers and as sterilizing agent for thermolabile materials. Although ethylene oxide is not common as an organic ...
Kinetics of sintering of polyethilene glycol and lanthanum doped aluminum oxide obtained by the sol-gel method / Uticaj dodatka polietilen-glikola i lantana na mehanizam sinterovanja aluminijum-oksida dobijenog sol-gel postupkom
(Association of Chemical Engineers of Serbia, 2011)
Sintering and crystallization of low-density polyethylene glycol (PEG) and lanthanum, La(III)-doped Al2O3 aerogels prepared from aluminum isopropoxide were investigated. The sintering behavior of non-doped and doped aerogels ...
Oxidation of hydroxide ions at platinum-modified zeolite electrode / Izvod oksidacija hidroksilnih jona na zeolitu modifikovanom platinom
(Association of Chemical Engineers of Serbia, 2012)
NaX zeolite was modified by platinum via impregnation/thermal decomposition technique, using Pt(II)-acetyl acetonate in acetone as an impregnating solution. The samples were characterized by scanning electron microscopy ...
Removal of diesel pollution by biochar – support in water remediation / Uklanjanje zagađenja dizela sorpcijom na biočađi – podrška remedijaciji kontaminiranih voda
(Association of Chemical Engineers of Serbia, 2021)
Water contaminated with diesel oil represents one of the greatest challenges in waste water
management. Water soluble fraction (WSF) is of particular interest because of its toxicity to
aquatic organisms and discharge ...
Phenolic profile of some fruit wines and their antioxidant properties
(Association of Chemical Engineers of Serbia, 2016)
