CARBON DIOXIDE REDUCTION IN STEELWORKS

摘要

In the method according to the invention for reducing carbon dioxide during the production of steel, carbon dioxide resulting from the steel production process is reacted with an electropositive metal in a combustion step and the resultant carbon monoxide is fed back into the steel production process. In said process, the carbon monoxide can be used in a direct reduction method as a reduction gas or can be fed to a blast furnace process. The reacted metal can also be recovered by electrochemical conversion from its oxides or salts. In particular, a form of regenerative energy can be used to recycle the electropositive metal.
