数据集使用建议 | 用户应注意,该数据集代表从‘摇篮到大门’的预焙阳极生产,包括原材料运输和所有生产阶段直到完成品,但不包括使用和处置阶段。由于预焙阳极公司未提供石油焦和煤沥青的具体生产数据,故采用了通用数据。原材料运输数据基于地区平均值,且未考虑对环境影响不大的其他要素。用户在将这些数据外推到不同地理或技术背景时应小心谨慎,应考虑运输、供应链和排放因子的地区变异性。 |
产品或过程的技术目的 | 此数据代表预焙碳阳极生产过程的生命周期评估,主要用于铝电解。预焙阳极是铝冶炼炉中的关键组成部分,对于铝土矿电解还原为铝金属至关重要。该过程涉及使用石油焦、煤沥青等材料,并经历粗碎、焙烧、模old、烘焙等过程制造阳极。 |

数据选择和组合原则 | 石油焦和煤沥青由多家供应商提供,预焙阳极公司无法提供生产数据。因此,本研究采用了数据库中的石油焦和煤沥青数据,而不是具体的生产数据。烧碱的数据来自文献,石油焦的数据和电力的 LCI 数据来自文献。在预焙阳极生产过程中,焙烧环节的天然气供应来自济南当地的天然气管道。根据实地调查,本研究使用的石油焦、沥青和冶金焦的运输距离分别为 150 公里、120 公里和 200 公里。本研究假设每辆运输车的载重量为 20 吨,平均功率为 220 千瓦时,运输阶段的主要能耗为燃油消耗,单位公路运输能耗为 1836 KJ/(吨/公里)。本研究以单位油耗的平均排放系数作为原材料运输车辆尾气排放的标准。 | ||||

采样程序 | A company in Jinan was selected as the research subject in this study. Currently, half of the world's prebaked anode products are produced in China. The production of the commercial prebaked anode in Shandong Province was 5.21 million tons in 2016, which accounts for 59% of the total production in China. As one of the large company in Shandong Province, the company chosen for case study can produce 400 thousand tons of prebaked anode annually. The production process is also typical for prebaked anode production in China. | ||||
