Carbothermal reaction
WebAs a clean energy carrier, hydrogen energy has become part of the global clean energy strategy and one of the necessary routes to achieve global carbon neutrality. Driven by renewable electricity, water electrolysis promises to be an ideal long-term hydrogen production method that can realize net zero carbon emissions. Compared with … WebJun 9, 2007 · Under the nitrogen atmosphere, carbothermal reactions of calcium oxide and magnetite began at about 900 and 820 °C, respectively. Above about 1200 °C, CaO reacted with carbon to form CaC 2, and the interaction between carbon and CaO was dominant. At the temperature range of 820−920 °C, Fe 3 O 4 was reduced quickly to Fe.
