COMPOSITION FOR OBTAINING FUEL BRIQUETTE Russian patent published in 2015 - IPC C10L5/02 C10L5/10 C10L5/14 

FIELD: chemistry.

SUBSTANCE: invention relates to composition for obtaining fuel briquette, which contains thermally processed coal fines and residues of petroleum processing as binding substance, it contains thermally processed coal fines to humidity not higher than 4-5%, thermally processed to humidity not higher than 4-5% sulfate hydrolytic lignin, neutralised with solution in ratio S:L as 1:5 of slaked lime in amount 1.34 kg per a ton of sulfate hydrolytic lignin and is subjected to mechanical activation, with the following component ratio, wt %: thermally processed coal fine - 74-75%, sulfate hydrolytic lignin - 11-15%, residues of petroleum processing - 15-10%.

EFFECT: increase of ecological safety due to reduction of fraction of emissions of sulfurous compounds in combustion of fuel briquettes.
