Cobalt impregnated natural and acid modified montmorilloniteas catalysts in heterogeneous catalytic oxidation of nicotine in the presence of Oxone®
(Belgrade : Serbian Ceramic Society, 2019)
Nicotine i.e. (S)-3-(1-methylpyrrolidin-2-yl) pyridine is an alkaloid present in significant quantities in tobacco leaves and can be found in wastewaters as an aftermath of tobacco manufacturing. Natural Wyoming originated ...
Nickel doped titanate catalysts for photocatalytic hydrogen generation
(Belgrade : Institute of Technical Sciences of SASA, 2019)
This study will focus on investigation of photocatalytic hydrogen production activity over low cost Ni modified titanates, as alternatives for highly cost and low-abundance noble metal based catalysts. The catalysts with ...
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 ...
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 ...
