摘要：
The implementation of carbon neutralization target will have a profound impact on the development of coal chemical industry and technology in China. This paper analyzes the overall CO2 emission of coal consumption and coal chemical industry and the role of coal chemical industry in the national economy, proposes that the coupling of carbon emission reduction technology and coal chemical process is the key to realize the carbon emission reduction and sustainable development of coal chemical industry and realistically choosing measures to optimize industrial structure and improve energy efficiency can significantly but limited reduce CO2 emission. In order to achieve CO2 emission reduction in 100 million ton scale, these technologies of green electricity and green hydrogen, CCS/CCUS and CO2 resource utilization must be adopted. The paper reviews the main progress on the technologies of green electricity and green hydrogen, CCS/CCUS and CO2 resource utilization in recent years, and points out that in the 10 years before the carbon peak in 2030, these carbon emission reduction technologies will be in the key demonstration test period. Whether they are mature and reliable will determine the development trend of coal chemical industry after the carbon peak. It is predicted that the demonstration application of hydrogen metallurgy and green ammonia synthesis will possibly lead to significant changes in the structure of coal chemical industry. Finally, the paper prospects and outlines the possible zero carbon chemical industry system based on the research progress of air direct capture CO2 technology and photo/electro-catalytic CO2 conversion or simulated photosynthetic reaction via CO2 and water. © 2022, Chemical Industry Press Co., Ltd.
