Research on the utilisation of waste chromic materials in the sodium chromate production process
Waste Management and Research, 2002The results of investigations on the utilisation of waste chromic materials for the production of sodium chromate have been presented. The optimal parameters of the sodium chromate production, which make it possible to select the best technological solutions, have been determined.

The influence of sodium on biohydrogen production from food waste by anaerobic fermentation
Journal of Material Cycles and Waste Management, 2009Anaerobic fermentation of food waste for hydrogen production was performed in serum bottles with various linear alkylbenzene sulfonate (LAS) dosages (7.1–21.4 g/l) and sodium concentrations (5.03–28.7 g/l). LAS can effectively inhibit the activity of hydrogen-consuming bacteria, and the maximum hydrogen yield of 109.2 ml/g volatile solid (VS) was ...

The use of metallurgical waste sludge as a catalyst in hydrogen production from sodium borohydride
International Journal of Hydrogen Energy, 2020Abstract In this study, the metallurgic sludge which contained oil and was obtained as waste of grinding, sharpening and milling parts was used in the production of hydrogen (H2) from sodium borohydride (NaBH4). The hydrolysis of NaBH4 with the metallurgic sludge catalyst was investigated depending on several parameters such as sodium hydroxide (NaOH)
