(Central and Eastern European Committee of Thermal Analysis and Calorimetry, 2019)
Are the Tube Microreactors Future of Wastewater Treatment?
(Belgrade : Association of Chemists and Chemical Engineers of Serbia UHTS, 2019)
In the industry, wastewater is important environmental problem. Due to the growing
environmental concern this problem became one of key issues. Large amounts of highly
contaminated wastewater, as consequence of industrial ...
Investigation of the dynamics of fluidized bed granulation process / Ispitivanje dinamike granulacije praškastih materijala u fluidizovanom sloju
(Serbian Chemical Society, Belgrade, 2019)
In this paper, experimental investigation of the dynamics of the process of fluidized bed granulation was performed, in order to find optimal process conditions and binder concentration to achieve the desired granules ...
Intensification of a chemical reactor for methanol synthesis through forced periodic operations- Evaluation based on Nonlinear Frequency Response Analysis
(2nd International Process Intensification Conference, Leuven, Belgium, 2019)
In this work, the NFR method is implemented for evaluation of possible improvement for the reaction of methanol synthesis by hydrogenation of CO and CO2, using a standard Cu/ZnO/Al2O3 catalyst. For start, a forced periodically ...
Purification of waste water using ozonization / Prečišćavanje otpadnih voda primenom ozonizacije
(Beograd : Beogradska politehnika, 2019)
Due to the development of industry and population growth during the in recent years, there are problems with wastewater from production that needs to be addressed in an environmentally and economical way. All wastewaters ...
Artificial Neural Network for Composite Hardness Modeling of Cu/Si Systems Fabricated Using Various Electrodeposition Parameters
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Copper coatings are produced on silicon wafer by electrodeposition (ED) for various cathode current densities. The resulting composite systems consist of 10 μm monolayered copper films electrodeposited from sulphate bath ...
Biodiesel synthesis over green catalyst: The effect of thermal treatment of CaO/Zeolite precursor on catalytic activity
(Belgrade : Serbian Chemical Society, 2019)
The green CaO/Zeolite catalyst for methanolysis of fatty oils was synthesized entirely from the waste materials. CaO derived from chicken eggshell was loaded onto fly ashbased zeolite catalyst carrier by the wet impregnation ...
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 ...
Cleaning and Desinfection a Part of Water Suplly System Ušće Zemun – Piramida New Belgrade / Pranje i dezinfekcija vodovodne mreže na relaciji Ušće Zemun – Piramida Novi Beograd
(Čačak : Univerzitet u Kragujevcu, Agronomski fakultet, 2019)
It was noticed worldwide that nutrient enrichment and climatic change as global warming and hydrologic changes with periods of more intense droughts strongly affect cyanobacterial growth. Toxigenic cyanobacteria that can ...
Washing and Desinfection of the Wells Type Reni / Hiperdezinfekcija bunara za vodosnabdevanje tipa Reni
(Čačak : Univerzitet u Kragujevcu, Agronomski fakultet, 2019)
We show in this work the treatment procedure utilized for cleaning and desnfection of water in water wells of large capacity as in the case of wells of Belgrade Waterworks. The typical examples of such well of large capacity ...
