Design and optimization of purification procedure for biodiesel washing
(Association of the Chemical Engineers of Serbia, 2009)
Almost complete methanolysis of triglycerides is usually not enough to fulfil the strict standards of biodiesel quality. A key step in this process is neutralization of alkali (catalyst) followed by the washing procedure ...
In situ lead stabilization using natural and synthetic apatite
(Savez hemijskih inženjera, Beograd, 2008)
In this work, mineral apatite was investigated for the remediation of lead contamination. Two different apatite minerals were used: synthetic apatite, Ca10(PO4)6(OH)2 (hereafter denoted as HAP) and natural apatite from ...
Immobilization of fish chromatophores for use as a micro-biosensor for biological toxins / Imobilizacija hromatofora riba radi korišćenja kao biosenzor za biološke toksine
(Association of the Chemical Engineers of Serbia, 2003)
Chromatophores isolated from the Siamese fighting fish, Betta splendens, represent a class of living cells that provide a vivid color response to microbial pathogens and environmental toxins. The selection of the most ...
Examination of localization of silymarin and fatty oil in Silybum marianum (L.) Gaertn. fruit
(Association of the Chemical Engineers of Serbia, 2007)
Physical characteristics and localization of flavonoids and fatty oil in Silybum marianum (L.) Gaertn. fruit of different origin were examined. Physical characteristics of the fruit were determined by its origin, and samples ...
Hydrodistillation kinetics and essential oil composition from fermented parsley seeds / Kinetika hidrodestilacije i sastav etarskog ulja fermentiranog semena peršuna
(Association of the Chemical Engineers of Serbia, 2005)
The effect of fermentation conditions on the yield and composition of the essential oil from Petroselinum crispum (Mill.) Nym. ex. A.W. Hill seeds was studied. The yield of essential oil was determined by a Clevenger-type ...
Antimicrobial textile prepared by silver deposition on dielectric barrier discharge treated cotton/polyester fabric
(Association of the Chemical Engineers of Serbia, 2008)
The objective of this research was to impart the additional value on cotton/polyester (Co/PES) fabrics (i.e. antimicrobial properties) to improve the quality of life and thus to tap new markets with the product. In this ...
Mathematical modeling of gel drying with supercritical carbon dioxide / Matematičko modelovanje sušenja gela natkritičnim ugljen dioksidom
(Association of the Chemical Engineers of Serbia, 2001)
The most complex step in the production of aerogels is the supercritical drying step, and it is therefore important to study its dynamics using mathematical models. Alumina/silica aerogel was obtained using a one step ...
A microwave-assisted liquefaction as a pretreatment for the bioethanol production by the simultaneous saccharification and fermentation of corn meal
(Association of the Chemical Engineers of Serbia, 2008)
A microwave-assisted liquefaction as a pretreatment for the bioethanol production by the simultaneous saccharification and fermentation (SSF) of corn meal using Saccharomyces cerevisiae var. ellipsoideus yeast in a batch ...
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 ...
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 ...
