Hydrogen production by biomass gasification / Proizvodnja vodonika gasifikacijom biomase
(Inženjersko društvo za koroziju, 2017)
Hydrogen could be the important energy sources of the next period provided that its production,
transportation, and storage are solved. In this paper review of the production of hydrogen from
lignocellulosic feedstock ...
Catalytic activity of sulfuric acid on the morphology of electrochemically obtained copper powder / Katalitičko delovanje sumporne kiseline na morfologiju elektrohemijski dobijenog bakarnog praha
(Belgrade, Serbia : Engineering Society for Corrosion, 2015)
The subject of the research is influence of sulfuric acid on morphology of electrochemically obtained copper powder during galvanostatic electrolysis mode. In this paper electrodeposition of copper powder from sulphate ...
Treatment of waste sulfuric acid copper electrolyte / Tretman otpadnog sumporno-kiselog elektrolita bakra
(Institut za rudarstvo i metalurgiju Bor, 2014)
The aim of this paper was to investigate the possibility of using the copper anodes with high nickel content for electrolytic treatment of waste sulfuric acid copper electrolyte. Nickel content in each anode was about 10 ...
