Abstract

In a short introduction tests and calculations about CO₂-ice-blocs in the deep sea, use of CO₂ for underground-coal-gasification and tertiary processes to increase oil-production by C02-flooding are shown. New activities are presented e.g. CO₂-injection into EAF combined with injection of coal, coke or directreduction-fines. After research of injection of coals, fine ores or dust into blast furnaces and other shaft furnaces activities are compared with injection of hot reducing gas generated by coal or waste gasification or top gas recycling combined with injection of fine solid fuels. Results of injection of prepared plastics (Duales System Deutschland), shredder-light-fraction from car-recycling and unburned carbon of power-station-ashes are discussed. Beside production of direct-reducediron by H₂ fluidized reactor results of the reduction behavior ore/coal or dust/coal pellets or briquettes for the use in rotary hearth or modem shaft furnaces are shown
