Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to make steel. Coke is used as a reducing agent in smelting iron ore in a blast furnace The carbon monoxide produced by its combustion reduces iron oxide (hematite) in the production of the iron product. But there is a problem associated with iron and steel industry firstly: increasing in the cost of coke (coking coal) and their quality and secondly: the reduction of iron oxide with coke in blast furnace is done completely or not which directly affected the production of pig iron. In this paper we describe about a catalyst (THERMACT-BF) after addition of catalyst on iron ore with hard coke. We found that coke quality increased. The degree of reduction of iron oxide with coke also increased as well as production of pig iron increased. The study of the catalyst THERMACT – BF on hard coke with iron ore it was observed that the efficiency of reduction of Iron Ore and Coke increased on addition of THERMACT-BF in the Blast furnace without any ill effect on the system.
