METHOD OF PARTIALLY BRIQUETTED CHARGE PREPARATION FOR COKING Russian patent published in 2009 - IPC C10L5/16 

FIELD: chemistry.

SUBSTANCE: invention concerns method of preparation for charge coking, involving binding agent preparation by mixing coal-tar resin obtained by high-temperature coal charge coking, raw antracene and lignite resin obtained by express pyrolysis of lignite and exposed to thermal processing; charge processing by binding agent in amount of 3-10 wt % for partial charge briquetting; and adding humic acids obtained from lignite and exposed to thermal processing, to partially briquetted charge in amount of 2-4 wt % of total coked coal weight in charge and binding agent.

EFFECT: extended raw material base for coking due to the use of accessible thermal and chemical processing products of lignite and increase of widespread gas and thin baking coals content in coking charge along with reduction of rare bituminous and coke coals, simplified cost-effective process of high quality coke.
