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 ...
Moisture management properties of plain knitted fabrics made of natural and regenerated cellulose fibres / Sposobnost upravljanja vlagom glatkih pletenina izrađenih od prirodnih i regenerisanih celuloznih vlakana
(Association of Chemical Engineers of Serbia, 2015)
Moisture management is a complicated process which is known to be influenced by a variety of fabric characteristics such as fibre nature (hydrophilic or hydrophobic), porosity and thickness. There are different aspects of ...
Determination of the ozone volumetric mass transfer coefficient in bubble column with two-fluid nozzle gas distributor / Određivanje zapreminskog koeficijenta prenosa mase ozona u barbotažnoj koloni sa dvofluidnom mlaznicom
(Association of Chemical Engineers of Serbia, 2015)
Experimental investigation of gas-liquid mass transfer of ozone in water, in bubble column with two-fluid nozzle gas distributor (BKDM), under different operating conditions, is presented in this work. The main objective ...
Synthesis, structure and solvatochromic properties of some novel 5-arylazo-6-hydroxy-4-(4-methoxyphenyl)-3-cyano-2-pyridone dyes: Hydrazone-azo tautomeric analysis
(Elsevier Science Bv, Amsterdam, 2015)
A series of eleven new 5-arylazo-6-hydroxy-4-(4-methoxyphenyl)-3-cyano-2-pyridone dyes was synthesized and their absorption spectra were recorded in twenty solvents in the range 300-600 nm. Different solvent parameters, ...
Impact testing with controlled energy of multiaxial aramid fabrics with various types of reinforcement / Ispitivanje udarima kontrolisane energije multiaksijalnih aramidnih lamina sa različitim tipovima ojačanja
(Savez inženjera i tehničara Srbije, Beograd, 2015)
The physical and mechanical properties of the six samples of polyurethane/p-aramid multiaxial fabric forms (Kolon fabrics) were analyzed by high speed impact tester. The samples were impregnated with 10 wt.% poly (vinyl ...
Sorption of cadmium ions from saline waters onto Fe(III)-zeolite / Sorpcija jona kadmijuma iz slanih voda na Fe(III)-zeolitu
(Association of Chemical Engineers of Serbia, 2015)
The sorption of Cd2+ from natural seawater, artificial seawater, distilled water and NaCl solution of the same ionic strength as the seawater onto zeolite modified by iron(III) oxide (Fe(III)-zeolite) was investigated. The ...
Adsorption of Candida rugosa lipase onto alumina: effect of surface charge
(Serbian Chemical Society, 2015)
The impact of the surface charge of alumina supports on the adsorption of Candida rugosa lipase was investigated in terms of the zeta potentials of the adsorption partners. The lipase adhered onto alumina with similar ...
Kinetic modeling and oprimization of fixed-bed reactor for Fischer-Tropsch synthesis
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2015)
Fischer-Tropsch synthesis (FTS) is a heterogeneously catalyzed chemical reaction in which a mixture of hydrogen and carbon-monoxide is converted into an array of hydrocarbon products. These products can be used as synthetic ...
