数据集使用建议 | 使用此聚丙烯(PP)生产数据集的用户需要考虑,数据主要来源于中国,当中国数据无法获取时,会使用欧洲的过程数据。在电力输入计算中正确应用此数据集至关重要,需要遵守中国国家电网结构。环境影响评估应使用ReCiPe方法(欧洲H/H),以确保与聚丙烯产量1公斤作为功能单元的数据一致性。当将这些数据迁移到其他地区,或在评估具有不同电网结构的场景时,应特别注意电力混合和技术适用性。 |
产品或过程的技术目的 | 聚丙烯(PP)生产是工业过程,其特点是通过前期原油精炼得到乙烯和丙烯,然后分别聚合成PE和PP。聚丙烯广泛应用于包装、纺织品、汽车部件和消费品等多种用途,得益于其多功能性、耐用性及可回收性。 |

时间代表性描述 | Process-based data from China were used, yet if not available, data from Europe were applied instead. The electricity input was developed based on the national grid structure in China (Table S3), which was obtained from the share of the electric power structure in 2020 (National Bureau Statistics of China, 2020). |
