Abstract:

A major part of the world’s iron production is presently using fossil reductants. The climate effect would be improved if renewable raw material could be used instead. One way could be to gasify biomass and use the gas to produce DRI (Direct reduced Iron). This is studied in a cooperative project. LTU, MEFOS, ETC and five industries in the areas forestry & pulp, mining, iron and gas are involved. The production chain Biomass production and distribution-Gasification-DRI production-DRI use is investigated in four work packages: WP1: Biomass supply, WP2: Gasification, WP3: Metallurgical processes and WP4: Process integration. The paper will focus on the studies and modeling of biomass supply, harvesting and transport and gasification as well as on the system studies. The use of the gas in the metallurgical application is briefly described as background.
