Research on the utilisation of waste chromic materials in the sodium chromate production process

Waste Management and Research, 2002
The 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, 2009
Anaerobic 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, 2020
Abstract 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)

Effect of sodium dodecylbenzene sulfonate on hydrogen production from dark fermentation of waste activated sludge

Science of the Total Environment, 2021
Sodium dodecylbenzene sulfonate (SDBS), a typical surfactant being widely used in various applications, was highly accumulated in waste activated sludge. To date, however, its effect on hydrogen production from dark fermentation of sludge has not been documented.

Utilisation of chromic waste in the sodium chromate (VI) production process

Journal of Loss Prevention in the Process Industries, 2002
This work presents research results on the utilisation of chromic waste in the production of sodium chromate (VI). The optimal parameters of the sodium chromate (VI) process which make it possible to select the best technological solution were determined.
