| 中文摘要 | 随着全球气候变化加剧，CO2排放问题已成为当前国际政治和环境的重要议题。2009年在哥本哈根气候变化会议上，我国承诺2020年单位GDP CO2排放量比2005年下降40%-45%。钢铁生产消耗大量煤焦类化石能源，我国钢铁工业CO2排放占我国总排放的15%左右，CO2减排已成为钢铁工业一个亟待解决的问题。目前我国针对钢铁生产CO2排放计算的研究仍处于起步阶段，本文采用物质流分析法对钢铁生产工序层次进行碳素流分析，建立钢铁生产各工序CO2排放计算方法，并结合对钢铁企业的实地调研，计算各工序CO2排放量；在碳素流分析的基础上，估算了钢铁行业煤炭氧化因子，并结合行业统计数据，计算我国钢铁行业CO2排放量。论文取得的创新性成果包括：（1）构建了材料含碳量数据集。选取典型钢铁企业，对钢铁生产涉及的含碳材料进行实地取样，进行材料含碳量检测和数据处理，建立材料含碳量数据集。（2）建立了钢铁生产工序层次CO2排放计算方法。采用物质流分析法，对高炉-转炉和废钢-电炉工艺生产涉及的炼焦、烧结、造球、高炉炼铁、转炉炼钢、电炉炼钢、精炼、铸造和轧钢工序进行碳素流分析，建立各工序层次CO2排放计算方法，并选取9家钢铁企业进行实证研究，计算各工序CO2的排放量。（3）计算钢铁行业CO2排放量。基于工序层次碳素流分析，建立氧化因子估算方法，并结合我国钢铁行业统计数据，计算我国钢铁行业CO2排放量。本论文的研究工作为钢铁生产CO2排放核算提供工序层次的方法指导，为钢铁行业CO2减排方法和技术的选择及减排策略的制定提供数据参考。 |
| 英文摘要 | CO2 emission has been an international political and environmental issue, due to its high contribution to the global climate change. China has promised to reduce the intensity of CO2 emissions per unit of GDP in 2020 by 40 to 45 percent compared with the level of 2005 in Copenhagen Climate Change Conference held in 2009. Iron and steel industry which consumes lots of fossil fuels accounts for about 15% of total CO2 emissions in China. So it is an urgent problem of CO2 emission reduction of iron and steel industry in China. Research about analysis of CO2 emissions from iron and steel making in China is few. In this work, the CO2 emissions in different steel production process and coal oxidation factor were discussed based on the Material Flow Analysis of carbon. The amount of CO2 emission from iron and steel industry in China was calculated based on the data from National Bureau of Statistics of China and field investigation of 9 enterprises. The following innovative results are obtained: (1) The data set of materials’ carbon content was established by field sampling and sample testing of carbonaceous materials involved in iron and steel production. And the data set could provide parameters for calculation of CO2 emissions in iron and steel making. (2) Based on material flow analysis of carbon in iron and steel production, the calculation model of CO2 emissions in different production processes was created, involving coking, sintering, pelletizing, blast furnace iron making, oxygen furnace steelmaking, EAF steelmaking, refining, casting and rolling in blast furnace - oxygen furnace and steel scrap - EAF. And the calculation model was applied in the analysis of CO2 emissions for 9 iron and steel enterprises in China. (3) The amount of CO2 emissions from iron and steel industry in China was calculated in this work. The oxidation factors in iron and steel production were calculated based on carbon flows of production processes. Further more, the amount of CO2 emissions from iron and steel industry in China was calculated by the data from National Bureau of Statistics of China and oxidation factors. The calculation model and data in this study are significant for further depth analysis of CO2 emissions, as well as for the choice of emission reduction technologies and formulation of emission reduction strategy. |
