COURSE 50 is an R&D project which involves the development of a set of technologies to reduce the CO₂ emissions from iron and steel production. The initiative involves reforming coke oven gas with the aid of catalysts and utulizing unused heat in the steel plant in order to increase its hydrogen content (from 55% to 67%). This hydrogen enriched gas is then to be used for the reduction of iron or in the blast furnace. Becuase this technology will reduce the amount of coke used in the blast furnace, improvment of coke properties to enable hyrdrogen reduction is also investigated. Collection and separation of CO₂ from blast furnace gas by using unused exhaust heat at steel mills is also being investigated.
