Abstract
A method reduces carbon dioxide resulting from a steel production process. The carbon dioxide is reacted with an electropositive metal in combustion to produce carbon monoxide. The resultant carbon monoxide is fed back into the steel production process. In this method, 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.
