Kinetics of heterogeneous methanolysis of sunflower oil with CaO·ZnO catalyst: Influence of different hydrodynamic conditions / Kinetika heterogene metanolize suncokretovog ulja sa CaO·ZnO kao katalizatorom - uticaj različitih hidrodinamičkih uslova
(Association of the Chemical Engineers of Serbia, 2014)
The kinetics of heterogeneous methanolysis of sunflower oil was studied at 60 °C using mechanochemically synthesized CaO·ZnO as catalyst. The influence of agitation speed, catalyst amount, and methanol-to-oil molar ratio ...
Photocatalytic degradation of carbamate insecticides: Effect of different parameters / Fotokatalitička degradacija karbamatnih insekticida - efekti različitih parametara
(Institute of Pesticides and Environmental Protection, 2019)
Photocatalytic degradation of a model compound of the carbamate insecticide carbofuran in water was studied using polychromatic light and ZnO and TiO2 catalysts. The influence of operational parameters, such as reaction ...
Biodiesel synthesis and kinetic analysis based on MnCO3/Na silicate as heterogeneous catalyst
(Srpsko hemijsko društvo, Beograd, 2018)
The MnCO3/Na silicate (Mn/Na/Si mole ratio of 4.65:1:1.65) catalyst in the form of solid particles with diameter of 0.99-1.99 mm was used as a catalyst for transesterification of soybean oil in batch autoclave at different ...
