The details of the inventory are presented as Table 1. It should be noted that the data for the material transportation assumptions are based on relevant studies, whic h may be slightly different from the actual situation. The life-cycle intensities of each end-use energy type are based on the results of our previous studies.能源输入和物流的清单来自更新的年鉴、发表的论文、官方报告和数据库。清单的详细信息如表1所示。需要注意的是，材料运输假设的数据基于相关研究，可能与实际情况略有不同。每种最终使用能源类型的生命周期强度基于我们之前研究的结果。None无None无Peng, T., Ou, X., Yan, X. & Wang, G. Life-cycle analysis of energy consumption and GHG emissions of aluminium production in China. in Energy Procedia vol. 158 3937–3943 (2019).Peng, T., Ou, X., Yan, X. & Wang, G. Life-cycle analysis of energy consumption and GHG emissions of aluminium production in China. in Energy Procedia vol. 158 3937–3943 (2019).When utilizing this dataset for Life Cycle Assessment (LCA) of aluminum products, users should consider the origin and transportation of bauxite as well as the energy sources used in alumina production. Recycling processes for aluminum should be considered, as they significantly affect the overall environmental impact. It is important to note that transportation assumptions made in this dataset may differ from real-world scenarios and should be updated or verified against current local conditions. Energy intensities for end-use processes should be based on the latest available data to reflect ongoing technological advances and efficiency gains.在使用此数据集进行铝制品生命周期评估（LCA）时，用户应考虑铝土矿的来源和运输以及在氧化铝生产中使用的能源。应考虑铝的回收过程，因为它们显著影响整体环境影响。重要的是要注意，此数据集中的运输假设可能与实际情况不同，应根据当前的当地条件进行更新或验证。终端使用过程的能源强度应基于最新可用数据，以反映持续的技术进步和效率提高。Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044.清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。Tiangong LCI Data Working Group天工LCI数据工作小组Zimeng Cai, caizm6178@163.com蔡梓萌, caizm6178@163.comcaizm6178@163.comcaizm6178@163.com2024-01-10T09:09:36+08:002024-04-20T15:31:14.812854+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=88b2235a-b5cf-4699-89f6-537c30bcd762&version=01.00.000&stock=TianGongTiangong LCI Data Working Group天工LCI数据工作小组falseFree of charge for all users and useshard coal; 26.3 MJ/kgInput15444.6099115444.60991Missing unimportantFuel mix: raw coal (72%), refined NG (13%), residual oil (5%), electricity (9%), coke (1%)natural gas, high pressureInput2788.6101232788.610123Missing unimportantFuel mix: raw coal (72%), refined NG (13%), residual oil (5%), electricity (9%), coke (1%)residual oilInput1072.5423551072.542355Missing unimportantFuel mix: raw coal (72%), refined NG (13%), residual oil (5%), electricity (9%), coke (1%)electricity, high voltage, aluminium industryInput1930.5762391930.576239Missing unimportantFuel mix: raw coal (72%), refined NG (13%), residual oil (5%), electricity (9%), coke (1%)Petroleum CokeInput214.508471214.508471Missing unimportantFuel mix: raw coal (72%), refined NG (13%), residual oil (5%), electricity (9%), coke (1%)quicklime, milled, looseInput280.0280.0Missing unimportantcalcined limeSodium hydroxideInput180.0180.0Missing unimportantcaustic sodabauxiteInput4620.04620.0Missing unimportantbauxitealuminium oxide, metallurgicalOutput1910.01910.0Missing unimportantalumina
