| Abstract: |
| Carbon materials for aluminum are one of the indispensable and important materials in the production process of aluminum smelting using molten alumina-cryolite salts. They are divided into carbon anode materials for aluminum and carbon cathode materials for aluminum, which cause a large amount of carbon dioxide emissions during the production process, including carbon dioxide emissions caused by physical and chemical reactions, carbon dioxide emissions caused by fuel combustion, and carbon dioxide emissions caused by energy consumption. However, there is little specific accounting for carbon emissions from the aluminum carbon industry in the existing literature, and there is no accounting for carbon emissions from the aluminum carbon industry in the IPCC National Greenhouse Gas Inventory Guidelines. Based on the material balance calculation in the specific production process of carbon materials for aluminum, this article focuses on the material balance accounting method, accounting for carbon emissions in the production process of aluminum prebaked anode and aluminum graphitized carbon cathode, clarifying relevant accounting formulas, and selecting relevant typical data for actual accounting. |
