Direct liquefaction of soft brown coal from the Kosovo basin / Likvefakcija mekog mrkog uglja kosovskog basena
(Association of Chemical Engineers of Serbia, 2000)
The behavior of Kosovo Basin (Yugoslavia) soft brown coal was studied during a direct liquefaction process by catalytic hydrogenation. A stream of hydrogen was passed through a tetralin dispersion of the pulverized coal ...
On the formation of porous structure during the synthesis of macroporous copolymers based on glycidyl methacrylate / Nastajanje porozne strukture pri sintezi makroporoznih kopolimera na bazi glicidilmetakrilata
(Association of Chemical Engineers of Serbia, 2004)
The results obtained during the investigation of the influence of the inert component composition and the type of copolymerization reaction on the porosity parameters of the macroporous copolymer of glycidyl methacrylate ...
Investigation of pretertiary and tertiary surface sediments from Serbia: Organic geochemical interpretation / Ispitivanje pretercijarnih i tercijarnih površinskih sedimenata Srbije - organsko-geohemijska interpretacija
(Association of Chemical Engineers of Serbia, 2002)
Samples of surface sediments originating from different localities in Serbia which contained more than 0.5 % organic matter were investigated in this paper. According to age, these samples were classified into two groups ...
Performances of continuous dryer with inert medium fluidized bed / Performanse kontinualne sušnice sa fluidizovanim slojem inertnih čestica
(Association of Chemical Engineers of Serbia, 2008)
A fluid bed dryer with inert particles represents a very attractive alternative to other drying technologies according to the main efficiency criteria, i.e. specific water evaporation rate, specific heat consumption and ...
Absorption in a three-phase fluidized bed II: Mass transfer investigations / Apsorpcija u koloni sa pokretnim punjenjem II - ispitivanja karakteristika prenosa Mase
(Association of Chemical Engineers of Serbia, 2003)
The absorption of carbon dioxide in aqueous diethanolamine solutions was carried out in a three-phase fluidized bed with inert spherical packing. The rate of absorption was calculated on the basis of measuring the concentration ...
The application of macroporous copolymers in the sorption of heavy and precious metals from aqueous solutions / Primena makroporoznih kopolimera u sorpciji teških i plemenitih metala iz vodenih rastvora
(Association of Chemical Engineers of Serbia, 2006)
Macroporous crosslinked poly(GMA-co-EGDMA) was synthesized by the suspension copolymerisation and functionalized by the ring-opening reaction of the pendant epoxy groups with ethylene diamine. The porosity parameters ...
Phase equilibria investigation and alloys characterization in Sn-In-Ag system / Ispitivanje fazne ravnoteže i karakterizacija legura u sistemu Sn-In-Ag
(Association of Chemical Engineers of Serbia, 2008)
Lead-free soldering has become very popular in the world recently, especially in electronics, because of high ecological demands in industry. Some of lead-free solder alloys are already used in electronic industry, but ...
Partial hydrogenation of edible oils: Synthesis and verification of the nickel catalyst / Parcijalno hidrogenovanje jestivih ulja - sinteza i verifikacija katalizatora na bazi nikla
(Association of Chemical Engineers of Serbia, 2002)
Developed in the late 1800s as a butter substitute, margarine is made with vegetable oils. Margarine was created by a scientist from Provence (France) Hippolyte Mege-Mouries, in response to an offer by the Emperor Louis ...
The influence of modification on structural, textural and adsorption properties of bentonite / Uticaj modifikacije na strukturna, teksturalna i adsorpciona svojstva bentonita
(Assoc Chemical Engineers Serbia, Belgrade, 2008)
Natural bentonite clay from the Bogovina locality in Serbia was Na-exchanged and modified using hexadecyll-trimethylammonium bromide as surfactant and organobentonite was obtained. The influence of modifications on the ...
Porous poly(methylmethacrylate) and poly(methylmethacrylate-co-acrylamide) / Porozni poli(metilmetakrilat) i poli(metilmetakrilat-co-akrilamid)
(Association of Chemical Engineers of Serbia, 2006)
The characteristics of two types of porous polymers: poly(methyl methacrylate) and copolymers of methyl methacrylate and acrylamide were investigated in this study. Poly(methyl methacrylate) was synthesized in suspension, ...
