Abstract
The heat treatment of high-boiling tar fractions from Berezovsk lignite (Kansk–Achinsk Basin) in a solid-fuel reactor to obtain lignite pitch is investigated. In addition, the use of the semicoke to reduce granulated phosphorus pellets from Dzhanatas ore is studied. The lignite pitch and semicoke may also be used in coking batch for the production of blast-furnace coke with improved properties; as binder in the production of domestic lignite-based fuel briquets; as binder in the sintering of Kovdorsk and Olenegorsk iron-ore concentrates at AO Severstal’; as binder in the production of anode masses for aluminum production; as binder in bricks and cold packing employed in the manufacture and sealing of electrolyzer hearths; and for pyrolysis with natural methane to increase the yield of ethylene.
