Targeting heat recovery and reuse in industrial zone
(Savez hemijskih inženjera, Beograd, 2017)
In order to reduce the usage of fossil fuels in industrial sectors by meeting the requirements of production processes, new heat integration and heat recovery approaches are developed. The goal of this study is to develop ...
Comparison of cubic-plus-association and soave-redlich-kwong equations of state for prediction of vapor-liquid equilibrium of fischer-tropsch reaction mixture
(Savez hemijskih inženjera, Beograd, 2019)
Predictions of vapor liquid equilibrium for Fischer-Tropsch mixtures were com-pared using the classical Soave-Redlich-Kwong (SRK) and cubic-plus-asso-ciation (CPA) equations of state. The performance of the two equations ...
Stress corrosion cracking resistance of aluminum alloy 7000 series after two-step aging / Otpornost aluminijumske legure serije 7000 prema naponskoj koroziji posle dvostepenog termičkog taloženja
(Association of the Chemical Engineers of Serbia, 2015)
The effect of one-step and a new (short) two-step aging process on the resistance to stress corrosion cracking of an aluminum alloy 7000 series was investigated, using slow strain rate test and fracture mechanics method. ...
Structure and properties of TEMPO-oxidized cotton fibers / Struktura i svojstva TEMPO-oksidisanih vlakana pamuka
(Association of the Chemical Engineers of Serbia, 2012)
In this paper, the influence of the catalytic oxidation using water soluble and stable nitroxyl radical 2,2',6,6'-tetramethylpiperidine-1-oxyl (TEMPO) on the structure and properties of cotton fibers was studied. In ...
Progress in the production of bioethanol on starch-based feedstocks
(Association of the Chemical Engineers of Serbia, 2009)
Bioethanol produced from renewable biomass, such as sugar, starch, or lignocellulosic materials, is one of the alternative energy resources, which is both renewable and environmentally friendly. Although, the priority in ...
Utilization of stillages from bioethanol production from various substrates
(Savez hemijskih inženjera, Beograd, 2019)
Stillage is a main by-product of the bioethanol industry and, depending on the origin of substrates for bioethanol production, it can be a significant pollutant affecting the profitability of bioethanol production. Directing ...
Influence of compression speed and deformation percentage on mechanical properties of calcium alginate particles / Uticaj brzine kompresije i procenta deformacije na mehaničke karakteristike kalcijum alginatnih čestica
(Association of the Chemical Engineers of Serbia, 2015)
Hydrogel particles are often used as carriers for the immobilization of enzymes, polyphenolic antioxidants, whole microbial, plant or mammalian cells. In many processes, the mechanical properties of alginate particles are ...
Bioethanol from corn meal hydrolyzates / Proizvodnja bioetanola na hidrolizovanom kukuruznom brašnu
(Association of the Chemical Engineers of Serbia, 2005)
The two-step enzymatic hydrolysis of corn meal by commercially available α-amylase and amyloglycosidase and the subsequent or simultaneous ethanol fermentation of the hydrolyzates by Saccharomyces cerevisiae yeast were ...
Influence of the hemp component in non-homogeneous yarns on the elastic behavior of knits made therefrom / Uticaj komponente na bazi konoplje u nehomogenim pređama na elastično ponašanje pletenina
(Association of the Chemical Engineers of Serbia, 2005)
One of the aims of producing non-homogeneous yarns is the improvement of their mechanical, aesthetic and comfort properties. In the case of hemp yarns, known by their predominantly technical uses, non-homogeneous yarns ...
The bioethanol production with the thin stillage recirculation
(Association of the Chemical Engineers of Serbia, 2009)
In this paper, the bioethanol production with the thin stillage recirculation in mashing was investigated. The mashing was performed with recirculation of: 0, 10, 20 and 30% of the thin stillage. The thin stillage recirculation ...
