Аннотация: The paper presents the results of the research on thermobriquetting of dense brown and gaseous coals from Kansk-Achinsk basin, brown and gaseous coal mixtures with no binding agent as well as a mixture of brown coal with hydrolyzed lignin as a binding agent. The heating values of the products were shown to increase 1,3-1,5 times in comparison with the raw coals аnd the volatile yields causing black smoke decrease by 11-13 %. Most efficient, strong moistureproof briquettes with the heating value of 25,50 МJ/kg were produced of the mixture of the B3 brown and gaseous coals. The addition of lignin to the brown coal allowed lowering the pressing temperature from 380-400 оC to 200-250 оC, thus improving the reliability of the press operation.
