Brown coal reserves in the GDR fuel balance now amount to nearly 20 × 10 9 tonnes. Because of the lack of "hard coal", more than 90% of the GDR''s primary energy is produced from brown coal. Brown coal is used for purposes that traditionally used "hard coal", for example, the metallurgical industry, heavy chemistry, railroad transportation.

Brown coal exit: A market mechanism for regulated closure ...

2015-12-1 · The brown coal generators bidding for closure would estimate their future expected profits under different scenarios of power station closures. The optimal basis for their analysis would be to estimate the expected future profits of all four plants under the scenarios for exit by each one of them. Each plant owner would then submit a bid that ...

Holistic Assessment of Biochar and Brown Coal Waste as ...

2021-3-2 · Biochar and brown coal waste (BCW) have high contents of carbon (C), recalcitrant organic detritus and humic acids equipped with extensive sorption capacities which are comparable to other activated carbon alternatives (Qi et al. 2011; Soria et al. 2020).Thus, biochar and BCW improve soil quality by increasing organic matter (OM) content and sorption capacity, which enhance soil …

Concentrating rare earth elements in brown coal humic ...

Mechanochemical activation of brown coal in the absence of reagents, as well as additives of sodium percarbonate, monosodium phosphate, and sodium chloride, was carried out. Mechanochemical activation does not cause degradation of humic acid–REE complexes contained in pristine coal.
