我国甲烷排放控制的中长期挑战与应对

张博,郭金玲,高俊莲,张国生,刘合

《中国工程科学》 2024年 第26卷 第2期   页码 185-197 doi: 10.15302/J-SSCAE-2024.07.007

摘要：

甲烷（CH4）是全球第二大温室气体，控制CH4排放兼具气候、环境、安全与经济效益；我国的CH4排放量较大，开展中长期CH4控排战略研究是强化我国温室气体减排能力体系建设的重要环节。本文从CH4排放控制的科学基础出发，辨识了我国CH4排放特征并剖析了CH4排放控制面临的中长期挑战；从总体管控思路、各领域CH4排放控制行动方向、减排技术与措施体系架构等方面阐明了我国中长期CH4排放控制的行动逻辑，进而提出了我国中长期CH4排放管控对策。研究认为，我国中长期CH4控排行动将面临排放总量大且部门及区域间迥异、排放演变趋势及具体路径不确定、技术减排与措施减排的潜力不明晰、减排风险量化及目标设定能力不足等问题。建议着眼长远，从设定全口径目标、责任分配与落实、筑牢减排能力、增强管控合力出发，战略谋划CH4排放控制工作，协同推进制度创新、科技创新、模式创新，加速实现我国从控制CH4排放向减少CH4排放的进程转变。

Analysis on carbon emission reduction intensity of fuel cell vehicles from a life-cycle perspective

《能源前沿（英文）》 2024年 第18卷 第1期   页码 16-27 doi: 10.1007/s11708-023-0909-1

摘要： The hydrogen fuel cell vehicle is rapidly developing in China for carbon reduction and neutrality. This paper evaluated the life-cycle cost and carbon emission of hydrogen energy via lots of field surveys, including hydrogen production and packing in chlor-alkali plants, transport by tube trailers, storage and refueling in hydrogen refueling stations (HRSs), and application for use in two different cities. It also conducted a comparative study for battery electric vehicles (BEVs) and internal combustion engine vehicles (ICEVs). The result indicates that hydrogen fuel cell vehicle (FCV) has the best environmental performance but the highest energy cost. However, a sufficient hydrogen supply can significantly reduce the carbon intensity and FCV energy cost of the current system. The carbon emission for FCV application has the potential to decrease by 73.1% in City A and 43.8% in City B. It only takes 11.0%–20.1% of the BEV emission and 8.2%–9.8% of the ICEV emission. The cost of FCV driving can be reduced by 39.1% in City A. Further improvement can be obtained with an economical and “greener” hydrogen production pathway.

Nitrous oxide formation and emission in selective non-catalytic reduction process

YANG Weijuan, ZHOU Junhu, ZHOU Zhijun, CEN Kefa

《能源前沿（英文）》 2007年 第1卷 第2期   页码 228-232 doi: 10.1007/s11708-007-0031-9

摘要： Pulverized coal-fired boilers are not nitrous oxide sources because of high temperature combustion. But selective non-catalytic reduction may produce NO by NO reduction reactions. Chemical kinetics calculation and experimental research were used to find out the mechanism between NO and N-agent species, N-agent/NO nitrogen stoichiometric ratio (NSR), reaction temperature, reaction time, etc. The results show that NO emission decreases with increasing reaction temperature and NSR decreases when reaction time is enough. NO concentration first increases then decreases as SNCR reactions keep on occuring. Ammonia SNCR tests indicated that NO emission was 0 7 μmol/mol. About 8.7% of NO was transformed to NO, and NO emission was 27.8 μmol/mol at urea-SNCR test. Urea-SNCR is likely to bring NO emission problem.

PCDD/Fs emission, risk characterization, and reduction in China’s secondary copper production industry

Haiqian LI, Yonglong LU, Li LI

《环境科学与工程前沿（英文）》 2013年 第7卷 第4期   页码 589-597 doi: 10.1007/s11783-013-0495-2

摘要： Secondary copper production is one of the key polychlorinated dibenzo- -dioxins and dibenzofurans (PCDD/Fs) emission sources in China, but research and data on this issue are rare. In 2004, when the Stockholm Convention entered into force in China, PCDD/Fs emissions from secondary copper production contributed to 32.2% of the total release. In this paper, PCDD/Fs emission dynamics from secondary copper industry were discussed and cumulative risks were characterized. From 2004 to 2009, industrial policies played an indirect role in PCDD/Fs reduction, but its effects are still limited. The Yangtze River Delta, Pearl River Delta and central regions were among the top three of dioxin emissions from secondary copper production in China. Shanghai, Shandong, Zhejiang, and Jiangxi had comparatively higher accumulated risk and were recommended as the priority regions for promoting PCDD/Fs emission control in China. From 2009 to 2015, the PCDD/Fs emission dynamics in the secondary copper industry were presented through simulation. PCDD/Fs emission equations were established, resulting in the recommendation of control technology conversion rate at 30% for small scale smelters and 51%–57% for large and medium-sized enterprises in 2015. In conclusion, both indirect policy and direct control technology retrofitting should be integrated for more effective PCDD/Fs emission reduction in secondary copper industry.

Manufacturer encroachment and carbon reduction decisions considering cap-and-trade policy and retailer

《工程管理前沿（英文）》 2024年 第11卷 第2期   页码 326-344 doi: 10.1007/s42524-024-0301-9

摘要： Low-carbon regulation and market competition present new opportunities and challenges for supply chain firms, emphasizing the significance of carbon reduction and channel encroachment in enhancing competitiveness. This study formulates various game models to evaluate manufacturers’ encroachment strategies (with or without encroachment) under different conditions of low-carbon investment by retailers. It investigates the operational decisions and carbon abatement strategies of firms under various scenarios. The findings reveal that encroachment elevates unit abatement levels but decreases wholesale prices and retailer profits when unit encroachment costs are below certain thresholds. In contrast, the manufacturer consistently benefits from channel encroachment. Retailer-initiated low-carbon investments can motivate manufacturers to reduce emissions. A lower carbon price potentially offers financial advantages to retailer engaging in such investments. Additionally, the likelihood of reduced environmental damage postchannel encroachment, compared to preprofessional encroachment, increases when the retailer invests in low-carbon initiatives. The retailer’s profit is inversely related to the carbon price, and a higher carbon price can strengthen the incentive effect of low-carbon investment on the manufacturer’s abatement endeavors.
