Mechanochemical synthesis of CaO·ZnO.K2CO3 catalyst: Characterization and activity for methanolysis of sunflower oil / Mehanohemijska sinteza CaO·ZnO.K2CO3, katalizatora - karakterizacija i aktivnost u metanolizi suncokretovog ulja
(Association of the Chemical Engineers of Serbia, 2015)
The goal of this study was to prepare a CaO·ZnO catalyst containing a small amount of K2CO3 and analyze its activity for biodiesel synthesis. The catalyst was prepared using the following procedure: CaO and ZnO (mole ratio ...
Amoxicillin photodegradation by nanocrystalline tio2
(Savez hemijskih inženjera, Beograd, 2017)
Nanocrystalline TiO2, synthesized by sol-gel route and characterized by XRPD, BET and SEM measurements, was applied in the photocatalytic degradation of amoxicillin, using an Osram Ultra-Vitalux (R) lamp as the light source. ...
Calcium oxide based catalysts for biodiesel production: a review
(Savez hemijskih inženjera, Beograd, 2016)
Vegetable oils are mainly esters of fatty acids and glycerol, which can be converted to fatty acid methyl esters (FAME), also known as biodiesel, by the transesterification reaction with methanol. In order to attain ...
A study of photocatalytic degradation of methomyl and its commercial product lannate-90
(Savez hemijskih inženjera, Beograd, 2020)
Photocatalytic degradation of the carbamate insecticide methomyl and its commercial product Lannate-90 in aqueous suspension of TiO2 and ZnO using an Osram ultra-vitalux lamp (315-400 nm) was investigated. The objective ...
Degradation of nicosulfuron using fenton and fenton-like reactions
(Savez hemijskih inženjera, Beograd, 2018)
Nicosulfuron, a sulfonylurea herbicide, was subjected to different Fenton reactions at pH of a nicosulfuron aqueous solution (pH 5). Usually, the optimal pH for the Fenton reaction is between 3 and 4, but the addition of ...
Pressure drop in packed beds of spherical particles at ambient and elevated air temperatures / Pad pritiska u pakovanom sloju sferičnih čestica na sobnoj i povišenim temperaturama
(Association of the Chemical Engineers of Serbia, 2015)
The aim of this work was the experimental investigation of the particle friction factor for air flow through a packed bed of particles at ambient and elevated temperatures. The experiments were performed by measuring the ...
Photodegradation of dimethenamid-p in deionised and ground water
(Savez hemijskih inženjera, Beograd, 2016)
The study of photodegradation of dimethenamid-P herbicide was performed in deionised and ground water using TiO2 as a catalyst under UV light. The effect of electron acceptor (H2O2), scavenger of (OH)-O-center dot radicals ...
Liquid chromatography and liquid chromatography-mass spectrometry analysis of donepezil degradation products / Analiza degradacionih proizvoda donepezila primenom tečne hromatografije i tečne hromatografije-masene spektrometrije
(Association of the Chemical Engineers of Serbia, 2015)
This study describes the investigation of degradation products of donepezil (DP) using a stability-indicating RP-HPLC method for determination of donepezil, which is a centrally acting reversible acetyl cholinesterase ...
Heterogeneous kinetics of vegetable oil transesterification at high temperature
(Savez hemijskih inženjera, Beograd, 2016)
Currently, the catalytic efficiency and reusability of the solid base catalysts cannot meet the demand of industrial biodiesel production under low temperature. The purpose of this study is to define the kinetics of ...
Modification of functional quality of beer by using microencapsulated green tea (camellia sinensis l.) And ganoderma mushroom (ganoderma lucidum l.) Bioactive compounds
(Savez hemijskih inženjera, Beograd, 2017)
Increasing interest in production of frequently consumed functional food products has focused the present study on implementation of microencapsulated Ganoderma mushroom and green tea bioactive compounds in beer production. ...
