Change in Carbon Dioxide (CO2) Emissions From Energy Use in China’s Iron and Steel Industry

Magnesia-stabilised zirconia solid electrolyte assisted electrochemical investigation of iron ions in a SiO2–CaO–MgO–Al2O3molten slag at 1723 K

“…Specifically, it is estimated that the carbothermic reduction process that is dominant in the current industry for the production of iron and steel contributes to about 5% of the total global anthropogenic CO2 emissions. 1 Hence, the current steelmaking industry faces difficult environmental challenges. For this reason, the ultra-low CO2 steelmaking (ULCOS) program has been set up in Europe with the aim to develop four breakthrough technologies that are expected to drastically reduce greenhouse gas emissions.…”

Effect of Applied Voltage on Electroreduction with Controlled Oxygen Flow of Molten Slag Containing FeO at 1723 K

“…1,2) Production of metallic iron through the molten oxide electrolysis (MOE) process using inert electrode is an alternative route of ironmaking to eliminate CO 2 emissions. [3][4][5][6][7] However, it causes such problems as low efficiency of electrolysis (to 30%), 5) difficulty in the selection of candidate anode materials 6) and controlling side reaction and so on.…”

Engineering Management Based on the Reduction of Carbon Dioxide Emissions: a Review

“…As the often used approach in carbon emission factors, logarithmic mean Division index (LMDI) play an important role in the research of CO 2 emissions in iron and steel Industry. For example, by LMDI technique, Sun et al (2011) decompose total change in CO 2 emissions into four factors: emission factor effect, energy structure effect, energy consumption effect, and steel production effect. And prove that steel production effect is the major factor which is responsible for the rise in CO 2 emissions; whereas the energy consumption effect contributes most to the reduction in CO 2 emissions.…”
