Reactivity of coke and process of its activation during layer coking

The main consumers of coke are blast furnaces. Reactivity of coke is one of the main indices characterizing its suitability for metallurgical process. Reactivity of coke determines rates of oxidation-reduction reactions in blast furnace and its consumption. In order to provide efficient operation of blast furnace it is necessary to maintain optimal level of reactivity and effective reaction surface of coke. Layer process is single process of producing the metallurgical coke in Russia. Regularities in formation of reactivity of metallurgical coke in this process have been investigated.
