Sinteza, karakterizacija in uporaba Al-SBA-15 katalizatorja
(Ljubljana, Slovenija : Slovensko kemijsko društvo, 2019)
Naraščajoče povpraševanje po varnih industrijskih procesih je pripeljalo do razvoja in uporabe okolju prijaznih trdnih katalizatorjev, namenjenih za uporabo pri kislinsko kataliziranih reakcijah z dodano vrednostjo. Kislinska ...
Who is the better candidate? Macroinvertebrates and diatoms for ecological status assessment of Sava Lake (Serbia)
(Zagreb : Croatian Association of Freshwater Ecologists, 2019)
Sava Lake was created from the right arm of the Sava River, and the inhabitants of Belgrade use the lake intensively for swimming and bathing. We analysed macrozoobenthos and epilithic diatom communities at six sites from ...
Alumina production from purified Bayer liquor / Proizvodnja glinice iz pročišćene Bayerove otopine
(Hrvatska: Hrvatsko društvo kemijskih inženjera i tehnologa
(HDKI), 2019)
Removal of some impurities from Bayer liquor, such as zinc compounds, allows obtaining alumina with low content of impurities incorporated in the crystalline structure. Impurities in alumina influence the quality of products ...
Numerical analysis of aerodynamic performance of offshore wind turbine
(Belgrade, Serbia : Serbian Society of Mechanics, 2019)
The increasing size of wind turbine blades leads to various flow phenomena which are
influenced by aerodynamic design of blade. Detailed information of flow separation and wake
development are important for wind turbine ...
Modelling the use of Industry 4.0 technologies with lean manufacturing
(Zrenjanin, Serbia : University of Novi Sad, Technical Faculty "Mihajlo Pupin", 2019)
The lean manufacturing approach has the potential to lower production costs and increase productivity through the reduction of various forms of waste. It is evident that lean manufacturing as a business model offers stable ...

Modified eggshell catalyst for transesterification of sunflower oil: The effects of catalyst loading on FAMEs content
(Belgrade : Serbian Chemical Society, 2019)
Modified highly active CaO catalyst (ESCHC-600) derived from waste chicken eggshells were prepared and used in the transesterification of sunflower oil. Eggshells were subjected to calcination-hydration-calcination (CHC) ...
Forced Periodic Operation: Effect of shapes for two simultaneously imposed modulations
(German reaction Engineering Meeting (DECHEMA), Wuerzburg, Germany, 2019)
The classical design of continuous chemical reactors exploits steady-state operation, which is optimized and maintained by appropriate control systems. Nevertheless, it is well-known that the reactor performance can be ...
