- Abstract:
- ... The coexistence of sulphate-reducing bacteria and methanogenic archaea in the reactors during the anaerobic digestion from sulphate-containing waste could favor the accumulation of sulfide on the biogas, and therefore reduce its quality. In this study, the effect of sulphate-reducing bacteria inhibitor ([Formula: see text]) addition in a two phase system from sulphate-containing municipal solid wa ...

- Abstract:
- ... Oil shales are low calorific fuels leaving upon processing large amounts of solid waste with limited secondary use, mostly because of low self-cementitious properties. In this paper, alkali activation of the waste remaining after shale oil retorting in solid-heat-carrier plants was investigated to improve the cementitious properties of this waste. The formation of secondary silicate binder phases ...
