METHOD OF PRODUCING FUEL BRIQUETTE Russian patent published in 2025 - IPC C10L5/00 C10L5/16 C10L5/28 C10L5/30 

FIELD: chemistry.

SUBSTANCE: invention relates to fuel and power industry. Invention relates to a method for producing a fuel briquette from residues of secondary oil refining processes, comprising steps of providing a carbon-containing mass; oil pitch is heated to 80 °C above its softening temperature to ensure minimum fluidity; carbon-containing mass is mixed with heated oil pitch; is moulded into charge briquette; charge briquette is calcined at temperature from 200 to 600-850 °C; finished briquette is cooled down.

EFFECT: obtaining a fuel briquette from residues of secondary oil refining processes with characteristics that allow its use in fuel, melting furnaces to create conditions for melting and/or reduction of mineral raw material of natural and/or man-made origin, novel method of producing fuel briquettes from residues of secondary oil refining processes which is cheap, simple and environmentally friendly.
