| 关于数据集的一般性意见 | 通常，铝电解是通过霍尔-埃鲁过程在电解槽中进行的，这一过程涉及在高温下通过电解熔融铝土矿（氧化铝）来制造金属铝。Life cycle inventory data in operation processes (including energy and raw material consumption) undertaken in Tongchuanxinguang aluminum production site of Tongchuan City in China were mainly collected from reference. Also, coal based electricity generation was used in this study. In addition, in case that China data were not available, data and relevant background data from European were used, including data on infrastructure, anode, and chemicals production. The life time of building and equipment considered in this study is 40 and 8 years, respectively. |
