Anorganski spojevi Fe, Ca, Ni i S u toplinski obrađenim metalurškim koksovima dobivenim uz dodatak aditiva

This paper deals with the investigation of coke samples produced from coking coal with addition of atmospheric residue and coal tar pitch additives. The content changes of Fe, Ca, Ni and S and types of their inorganic compounds during coke heat treatment up to 1200, 1600, 2000 and 2400 C were investigated. Coke samles were heated 2 and 4 hours. The obtained results showed partially separation of investigated metals and sulphur and transformation their compounds during heat treatment. More desulphurization and metal separation were obtained for coke produced with coal tar pitch additive.
