Synergistic utilization of coal and other energy – Key to low carbon economy

Weidou NI, Zhen CHEN

《能源前沿（英文）》 2011年 第5卷 第1期   页码 1-19 doi: 10.1007/s11708-010-0136-4

摘要： In China, coal is a dominant component of energy mix, and it is expected to remain as such over the next 30 to 40 years. Coal is expected to be used even more in power generation. The direct combustion of coal already has been causing severe pollution and ecological degradation, and it is quite difficult to address the need to reduce greenhouse gas (GHG) given the direct combustion of coal. Therefore, the polygeneration system based on coal gasification, which is one of the major examples of synergistic utilization of coal, is proposed. It is a comprehensive solution to meet the energy challenges China is facing. Furthermore, the synergy of fossil fuels (especially coal) with renewable energy, the synergy of different kinds of energy for energy storage, the synergy of centralized and distributed supply of different kinds of energy, and the synergy of different kinds of energy in smart energy grid (power, gas, heat, and water) are the keys to making China a low-carbon economy. Carbon dioxide (CO ) mitigation in China should begin from the coal-chemical industry given their accumulated relevant experiences. The mitigation process should gradually be transformed into the “IGCC+ polygeneration+ CCUS”. The objectives of this paper are to describe the synergistic utilization of coal, and to analyze the synergy of coal with other energy resources, and to propose the scientific and technological problems to achieve these synergies.

Progress in developing an innovative lean burn catalytic turbine technology for fugitive methane mitigationand utilization

Shi SU, Xinxiang YU

《能源前沿（英文）》 2011年 第5卷 第2期   页码 229-235 doi: 10.1007/s11708-011-0147-9

摘要： Approximately 2.8 × 10 m of methane is emitted per year to the atmosphere from coal mining activities around the world. Mitigation and utilization of the fugitive coal mine methane is very difficult because its concentration is very low and varies from 0.1% to1%, and the methane is contained in a large air flow rate of 150–400 m /s. This paper overviews existing and developing technologies for the mitigation and utilization of the fugitive mine methane, and then presents research progress in developing an innovative lean burn catalytic turbine technology for fugitive methane mitigation and utilization. This turbine system can be powered with about 1% methane in air.

Enhanced permeability and biofouling mitigation of forward osmosis membranes via grafting graphene quantum

《化学科学与工程前沿（英文）》 2023年 第17卷 第10期   页码 1470-1483 doi: 10.1007/s11705-023-2329-5

摘要： In this paper, graphene oxide quantum dots with amino groups (NH2-GOQDs) were tailored to the surface of a thin-film composite (TFC) membrane surface for optimizing forward osmosis (FO) membrane performance using the amide coupling reaction. The results jointly demonstrated hydrophilicity and surface roughness of the membrane enhanced after grafting NH2-GOQDs, leading to the optimized affinity and the contact area between the membrane and water molecules. Therefore, grafting of the membrane with a concentration of 100 ppm (TFC-100) exhibited excellent permeability performance (58.32 L·m–2·h–1) compared with TFC membrane (16.94 L·m–2·h–1). In the evaluation of static antibacterial properties of membranes, TFC-100 membrane destroyed the cell morphology of Escherichia coli (E. coli) and reduced the degree of bacterial adsorption. In the dynamic biofouling experiment, TFC-100 membrane showed a lower flux decline than TFC membrane. After the physical cleaning, the flux of TFC-100 membrane could recover to 96% of the initial flux, which was notably better than that of TFC membrane (63%). Additionally, the extended Derjaguin–Landau–Verwey–Overbeek analysis of the affinity between pollutants and membrane surface verified that NH2-GOQDs alleviates E. coli contamination of membrane. This work highlights the potential applications of NH2-GOQDs for optimizing permeability and biofouling mitigation of FO membranes.

Lizhong ZHU, Li LU, Dong ZHANG

《环境科学与工程前沿（英文）》 2010年 第4卷 第4期   页码 373-386 doi: 10.1007/s11783-010-0253-7

摘要： Organic contaminated soils have become a widespread environmental problem, which may lead to a great threat to the quality of agricultural production and to human health. Physical, chemical, and biological technologies have been employed for the mitigation and remediation of organic contaminated soils. This paper reviews the progress of mitigation and remediation technologies for organic contaminated soils and suggests two different strategies for the mitigation of ‘slightly-contaminated’ agricultural soils and the remediation of ‘heavily-contaminated’ soils/sites, respectively. On this basis, directions for future research in this field are suggested.

Necessity of integrated methodology for hazard mitigation of quake lakes: case study of the Wenchuan

Xudong FU, Fan LIU, Guangqian WANG, Wenjie XU, Jianxin ZHANG

《结构与土木工程前沿（英文）》 2011年 第5卷 第1期   页码 1-10 doi: 10.1007/s11709-011-0099-5

摘要： The massive 8.0-magnitude Wenchuan Earthquake triggered huge landslides, avalanches, and debris flows that blocked rivers and created 34 important quake lakes, including the Tangjiashan Quake Lake on the Tongkou River. More than half of these lakes were identified to be of moderate or high hazard levels, so activities needed to be undertaken for hazard mitigation of potential flooding. This paper presents the mitigation processes of quake lake hazards, which involve various techniques such as rapid hazard analysis, scenario-based mitigation planning, and real-time forecasting of outburst flooding for implementation actions. The shortage of hydrologic and geological data and the nature of emergency situations raise substantial challenges in the hazard mitigation of quake lakes. This paper suggests a potential approach in dealing with quake lake hazards, which integrates the automatic monitoring network, hydrologic models, and hydrodynamic models with a comprehensive indicator for hazard levels. The necessity of improving the integrated methodology is highlighted.

Drivers of the development of global climate-change-mitigation technology: a patent-based decomposition

Liying SONG, Jun JING, Kerui DU, Zheming YAN

《能源前沿（英文）》 2021年 第15卷 第2期   页码 487-498 doi: 10.1007/s11708-021-0739-y

摘要： The development of the climate-change-mitigation technology has received widespread attention from both academic and policy studies. Nevertheless, very few studies have explained how and why economies contribute differently to global development. This paper decomposed the development of the global climate-change-mitigation technology, proxied by patent-based indicators, from 1996 to 2015 into several predefined factors. The results show that the worldwide surge of climate-change-mitigation-technology patents from 1996 to 2011 is driven by increased concentration on green invention, improved research intensity, and enlarged economic scale, while the falling of patent counts from 2011 to 2015 is predominantly due to less concentration on green invention. Among different climate-change-mitigation technologies, the type-specific development is attributed to different dominant factors, and the resulting priority change can reflect the shift of both global research and development (R&D) resource and market demand. Regarding regional contributions, the resulting economy-specific contributions to each driving factor can be used to design the policies to promote the development of the global climate-change-mitigation technology.

Advanced purification and comprehensive utilization of yellow phosphorous off gas

Ping NING,Xiangyu WANG

《环境科学与工程前沿（英文）》 2015年 第9卷 第2期   页码 181-189 doi: 10.1007/s11783-014-0698-1

摘要： Yellow phosphorous is an important raw material in the chemical industry. However, during the production of yellow phosphorous, high concentrations of carbon monoxide and other impurities are released. Without appropriate purification and removal, this off gas has potential to cause severe pollution problems once released. Purified yellow phosphorous off gas can be beneficially reused as a raw material in chemical production for synthesis of high value-added chemical reagents. In this paper, the significance of purification and reutilization of yellow phosphorous off gas are explored. The principles, processes, and main characteristics of the technologies for purification and reuse of yellow phosphorus off gas (including technical measurements of impurity reduction, relevant engineering cases, and public acceptance of the technologies) are summarized. In view of the existing problems and scientific development requirements, this paper proposes several recommendations for green production based on the concept of recycle economics. We conclude that advanced purification and comprehensive reutilization can be an effective solution for heavy pollution resulting from yellow phosphorous off gassing.

《工程管理前沿（英文）》 2016年 第3卷 第4期   页码 356-361 doi: 10.15302/J-FEM-2016057

摘要： Deepwater oilfields will become main sources of the world’s oil and gas production. It is characterized with high technology, huge investment, long duration, high risk and high profit. It is a huge system project, including exploration and appraising, field development plan (FDP) design, implementation, reservoir management and optimization. Actually, limited data, international environment and oil price will cause much uncertainty for FDP design and production management. Any unreasonable decision will cause huge loss. Thus, risk foreseeing and mitigation strategies become more important. This paper takes AKPO and EGINA as examples to analyze the main uncertainties, proposes mitigation strategies, and provides valuable experiences for the other deepwater oilfields development.

Aerodynamic interference effects and mitigation measures on vortex-induced vibrations of two adjacent

Xiaoliang MENG, Ledong ZHU, Zhenshan GUO

《结构与土木工程前沿（英文）》 2011年 第5卷 第4期   页码 510-517 doi: 10.1007/s11709-011-0129-3

摘要： By examining the two neighboring Haihe Bridges with semi- and full-closed bridge decks, the aerodynamic interference between the two decks on the vortex-induced vibration (VIV) and the corresponding aerodynamic mitigation measures are investigated via a series of wind tunnel tests with a spring-suspended sectional model aided with computational fluid dynamics (CFD) method. The results show that the VIV responses of both bridges can be significantly affected by the aerodynamic interference and that the extent of the influence varies with the shapes of the windward and leeward decks. The VIV amplitudes of the windward bridge are often fairly close to those of the single bridge. However, those of the leeward bridge are magnified substantially by aerodynamic interference if the same structural and aerodynamic configurations are adopted for the two bridges. Otherwise, the VIV responses are not significantly increased and may even be reduced by the aerodynamic interference if different configurations are employed for the two bridges. Furthermore, an effective combined measure of adding wind barriers and sharpening the wind fairing noses of the two box decks is presented for mitigating both the vertical and torsional VIV responses of the windward and leeward bridges.
