FIELD: oil and gas industry.
SUBSTANCE: invention relates to a method of making fuel briquettes from biomass, involving heat treatment of biomass at temperature of 200-500°C without access to air, preparing binding substance obtained by dissolving dextrin in a pyrolysis condensate in ratio of 1:(5-20), mixing the binder with a carbon residue ground to particle size of 2 mm, moulding a fuel briquette from the obtained mixture and drying said briquette at room temperature for 2-5 days. The obtained briquettes have low combustion heat, improved mechanical strength and resistance to compression.
EFFECT: use of the disclosed method widens the range of solid fuel, the raw material base for making briquettes and reduces technological expenses on making briquettes.
