The R&D of Flue Gas Pollutants Deep-Removal Technology for Coal-fired Power Plants

Xiao-lu Zhang

《工程管理前沿（英文）》 2015年 第2卷 第4期   页码 359-363 doi: 10.15302/J-FEM-2015057

摘要： The flue gas pollutants deep-removal technology (DRT) focusing on PM removal is the prime method of further reducing pollutants emission from coal-fired power plants. In view of the four key technological challenges in developing the DRT, studies were conducted on a series of purification technologies and the DRT was developed and successfully applied in 660 MW and 1000 MW coal-fired units. This paper analyzes the application results of the demonstration project, and proposes a roadmap for the follow-up researches and optimizations.

Efficient elimination of environmental pollutants through sorption-reduction and photocatalytic degradation

Njud S. Alharbi, Baowei Hu, Tasawar Hayat, Samar Omar Rabah, Ahmed Alsaedi, Li Zhuang, Xiangke Wang

《化学科学与工程前沿（英文）》 2020年 第14卷 第6期   页码 1124-1135 doi: 10.1007/s11705-020-1923-z

摘要： With the rapid development of industrial, large amounts of different inorganic and organic pollutants are released into the natural environments. The efficient elimination of environmental pollutants, i.e., photocatalytic degradation of persistent organic pollutants into nontoxic organic/inorganic chemicals, solidification or sorption-reduction of heavy metal ions, is crucial to protect the environment. Nanomaterials with large surface area, active sites and abundant functional groups could form strong surface complexes with different kinds of pollutants and thereby could efficiently eliminate the pollutants from the aqueous solutions. In this review, we mainly focused on the recent works about the synthesis of nanomaterials and their applications in the efficient elimination of different organic and inorganic pollutants from wastewater and discussed the interaction mechanism from batch experimental results, the advanced spectroscopy techniques and theoretical calculations. The adsorption and the photocatalytic reduction of organic pollutants and the sorption/reduction of heavy metal ions are generally considered as the main methods to decrease the concentration of pollutants in the natural environment. This review highlights a new way for the real applications of novel nanomaterials in environmental pollution management, especially for the undergraduate students to understand the recent works in the elimination of different kinds of inorganic and organic chemicals in the natural environmental pollution management.

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

《能源前沿（英文）》 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.

《环境科学与工程前沿（英文）》 2013年 第7卷 第3期   页码 302-325 doi: 10.1007/s11783-013-0511-6

摘要： This review reports the research progress in the abatement of major pollutants in air and water by environmental catalysis. For air pollution control, the selective catalytic reduction of NO (SCR) by ammonia and hydrocarbons on metal oxide and zeolite catalysts are reviewed and discussed, as is the removal of Hg from flue gas by catalysis. The oxidation of Volatile organic compounds (VOCs) by photo- and thermal- catalysis for indoor air quality improvement is reviewed. For wastewater treatment, the catalytic elimination of inorganic and organic pollutants in wastewater is presented. In addition, the mechanism for the procedure of abatement of air and water pollutants by catalysis is discussed in this review. Finally, a research orientation on environment catalysis for the treatment of air pollutants and wastewater is proposed.

Permitted emissions of major air pollutants from coal-fired power plants in China based on best available

Xiaohui Song, Chunlai Jiang, Yu Lei, Yuezhi Zhong, Yanchao Wang

《环境科学与工程前沿（英文）》 2018年 第12卷 第5期 doi: 10.1007/s11783-018-1065-4

摘要：

We proposed the SO2 and NOx emission performance standards for coal-fired power plants based on the best available control technology.

The CFPGUs’ SO2 emission performance reference values should be 0.34 g/kWh for active units in general areas and 0.13 g/kWh for newly built units and active units in key areas.

The CFPGUs’ NOx emission performance standard reference values should be 0.35 g/kWh for active units in general areas and 0.175 g/kWh for new units and active units in key areas.

关键词： Coal-fired power-generating units (CFPGU)     Emission performance     Best available control technology
