Kompiziti na bazi sirovog fosfata kao prirodna đubriva i remedijacioni agensi / Raw phosphate composite as a natural fertilizer and soil remediation amendment
(Inženjersko društvo za koroziju, Beograd, 2013)
Naša istraživanja su bila usmerena ka dizajniranju novog multifunkcionalnog materijala na bazi sinergističkog dejstva sirovog fosfata i modifikovanog zeolita amonijum jonima i otpadne biomase, u cilju povećanja fosfo-mobilizacije ...
Održiva konverzija otpadne biomase primenom postupka hidrotermalne karbonizacije / Sustainable conversion of waste biomass using hydrothermal carbonization method
(Inženjersko društvo za koroziju, Beograd, 2015)
Hidrotermalna karbonizacija predstavlja postupak prevođenja vlažnog organskog materijala primenom povišene temperature i pritiska u hidročađ, proizvod sličan uglju. Dobijena hidročađ, u zavisnosti od prirode biomase, može ...
Exploitation properties of ni-pd/al2o3 catalyst supported on ceramic foam
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The goal of this research was to examine exploitation properties of Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam in the dry methane reforming. The catalyst was prepared by using aerosol method. Chloride precursors ...
Application of raw volcanic rock found in etna valley as an adsorbent of chromates, arsenates and selenates
(Savez inženjera metalurgije Srbije, Beograd, 2018)
This paper aims to determine the potential of volcanic rock found in Etna valley as an adsorbent of heavy metals in anionic form (chromates, arsenates, and selenates). Characterization of the volcanic rock was done with ...
Influence of chalcopyrite structure on their leaching by sodium nitrate in sulphuric acid
(Savez inženjera metalurgije Srbije, Beograd, 2014)
During the chalcopyrite leaching by sodium nitrate and sulfuric acid solution, leaching rate decreases with increasing the time and a part of chalcopyrite mineral grains remains in the leach residue. In chalcopyrite ...
