METHOD OF PRODUCING CARBON-CONTAINING BRIQUETTES, CARBON-CONTAINING BRIQUETTE AND METHOD OF PROCESSING HEAVY OIL STOCK Russian patent published in 2025 - IPC C10L5/16 C10G47/22 

FIELD: performing operations.

SUBSTANCE: invention relates to a method of producing carbon-containing briquettes. Method includes steps of: loading carbon-containing filler, preheated binder, water into mixer and mixing; while stirring, the obtained mixture is heated to temperature of 85-95 °C; after mixing, the charge is fed into the press and briquettes are formed with pressing force of not less than 100 kN. Filler is a spent coal additive after the process of thermal hydrocracking of heavy oil stock, and the binder is a tar or a concentrated unconverted residue of hydrocracking of heavy oil stock. Components are loaded into the mixer at the following ratio: per 100 parts by weight of the spent coal additive, 3-5 parts by weight of water, 5-7 parts by weight of tar or 4-5 parts by weight of concentrated unconverted hydrocracking residue are added. Invention also relates to a method of processing heavy oil stock and a carbon-containing briquette.

EFFECT: proposed invention makes it possible to efficiently recycle wastes of oil refineries.
