中国作为全球最大的煤化工产品生产国，面临着巨大的碳减排压力。因此，有必要准确量化中国煤化工行业的二氧化碳（CO2）排放量。但由于煤化工产品的多样性以及CO2排放因子的限制，煤化工行业的CO2排放总量尚未确定。本研究根据23家煤化工企业的第一手数据，公布了中国当地煤化工产品的CO2排放因子，并推断出中国煤化工行业的CO2排放总量。提出省级煤化工CO2排放空间分布，协助政府确定重点减排区域。此外，还对2020年中国现代煤化工行业CO2排放进行了情景分析，以确定现代煤化工行业的发展是否会对未来CO2排放产生显着影响，以及碳捕集、利用和封存技术对碳排放减排的效果。测算显示，2015年煤化工行业二氧化碳排放总量为6.07亿吨，约占中国二氧化碳排放总量的5.71%。这个数字高于加拿大（555 公吨）或巴西（486 公吨）等国家的年二氧化碳排放总量。因此，量化煤化工行业的排放对于了解全球碳预算至关重要。从空间分布来看，山东、内蒙古、山西三省的煤化工CO2排放量占全国三分之一。考虑到现代煤化工的发展，预计2020年其CO2排放量将高达41652万吨。而当碳捕集、利用和封存同时应用于工艺和能源系统时，CO2排放量可减少31798万吨。本文首次量化了我国煤化工行业的CO2排放量，识别了重点化工产品及其生产省份，通过情景分析探讨了碳减排潜力，为评估有效的CO2减排政策提供了具体数据支撑。
As the largest producer of coal chemical products in the world, China faces tremendous pressure to reduce its carbon emission. An accurate quantification of the carbon dioxide (CO2) emission of coal chemical industry in China is therefore necessary. However, due to the variety of coal chemical products and limitations of CO2emission factors, the total CO2emission of coal chemical industry has yet to be determined. In this study, local CO2emission factors of coal chemical products in China are published based on first hand data from twenty-three coal chemical enterprises and the total CO2emission of China's coal chemical industry is extrapolated. The provincial-level spatial distribution of the CO2emission of coal chemical industry is presented to assist the government in identifying key emission reduction areas. Additionally, scenario analysis of CO2emission for China’s modern coal chemical industry in 2020 is conducted to determine whether the development of the modern coal chemical industry will have a significant impact on future CO2emission, as well as the effect of carbon capture, utilization and storage technologies on the reduction in carbon emission. The estimate shows that the total CO2emission of the coal chemical industry in 2015 was 607 million tonnes (Mt), accounting for approximately 5.71% of China’s total CO2emission. The figure is higher than the total annual CO2emission of a country such as Canada (555 Mt) or Brazil (486 Mt). Quantifying the emission of the coal chemical industry is therefore critical to understand the global carbon budget. The spatial distribution shows that Shandong, Inner Mongolia and Shanxi release one-third of the coal chemical industry’s total CO2emission. Considering the development of the modern coal chemical industry, its CO2emission is predicted to be as high as 416.52 million tonnes in 2020. However, the CO2emission could be reduced by 317.98 million tonnes when carbon capture, utilization and storage are applied to process and energy systems simultaneously. This paper quantifies the CO2emission of the coal chemical industry in China for the first time, identifies key chemical products and the provinces in which they are produced, explores the carbon reduction potential by scenario analysis, and provides specific data to support the assessment of effective CO2reduction policy.
