Carbon Reduction Programs and Key Technologies in Global Steel Industry

引用

Journal of Iron and Steel Research International 2014年第3期21卷 275-281页

作者： Jian-xun FU guo-hao TANG Ren-jie Zhao Weng-sing HWANG Key Laboratory of Modern Metallurgy and Materials Processing Shanghai University Department of Materials Science and Engineering Research Center for Energy Technology and StrategyNationalCheng Kung University

Greenhouse gases, particularly the carbon dioxide, cause global warming and extreme weather, which has become a serious threat to human beings. The steel industry creates enormous amounts of carbon emission and has tremendous potential in carbon reduction. Considering the consistently increasing demand of iron and steel, to obtain significant carbon reduction by reducing the steel production is not practical, thus the development and implementa- tion of carbon reduction programs and technologies is important for the steel industry. Despite the significant poten- tial of carbon reduction in the steel industry, ironmaking and steelmaking processes are complex. Therefore, resear- ches and developments for the carbon reduction must focus on key processes. Here, key processes and technologies adopted in ULCOS program in EU, COURSE 50 program in Japan, POSCO program in South Korea, AISI pro- grams in US and other carbon reduction programs are summarized and evaluated, and feasible suggestions for carbon reduction in developing countries are presented. If effective measures can be referred to and taken in developing coun- tries, global carbon emission can be greatly reduced.

Pollen-Ovule Ratio and Gamete Investment in Pedicularis （Orobanchaceae）

引用

Journal of Integrative Plant Biology 2007年第2期49卷 238-245页

作者： Chun-Feng Yang You-hao guo College of Life Sciences Wuhan University Wuhan 430072 China

The Pedicularis species provides ideal materials to study floral evolution because of their substantial flower variation based on a narrow genetic basis, even though they are almost exclusively pollinated by bumblebee. These traits allow us to detect the evolutionary trends of floral parameters without considering genetic background and the difference of pollination vectors. The pollen-ovule ratio is widely used to estimate the pattern of resource investment in two sexual functions in flowering plants. Forty species representing all of the corolla types in Pedicularls were used to study pollen-ovule ratio, gamete investment, and their correlations. Results show that pollen-ovule ratio does not differ among both different corolla types and taxonomic groups. It is therefore suggested that pollen-ovule ratio should be a parallel evolution. The correlations between pollen-ovule ratio and pollen size （-）, and ovule size （＋） can be successfully explained in terms of sex allocation theory. The biological significance of such relationships was also discussed. Additionally, we analyzed the pattern of resource investment into female gamete, which has been somewhat neglected, and found that plants have different patterns of gamete investment between the two sexual functions.

China Particuology 2005年第6期3卷 310-316页

作者： Chen guo hao Wen Huizhou Liu Lahoratory of Separation Science and Engineering State Key Laboratory of Biochemical EngineeringInstitute of Process EngineeringChinese Academy of Sciences.P.O.Box 353Beijing 100080P.R.China

In this paper we review our work on self-assembly of the system, poly（ethylene oxide）-poly（propylene oxide）-poly（elhylene oxide）（PEO-PPO-PEO） block copolymers, which is a kind of macromolecular complex fluids. The control of self-assembly could be obtained by adding inorganic salts or aliphatic alcohols. By self-assembly of amphiphilic block copelymers a microemulsion phase is formed which could be applied in micelle extraction, such as hollow-fiber membrane micelle extraction, magnetic micelle extraction and immobilized micelle extraction.

Effect of occurrence mode of heavy metal elements in a low rank coal on volatility during pyrolysis

引用

International Journal of Coal Science & Technology 2019年第2期6卷 235-246页

作者： Lingmei Zhou hao guo Xiaobing Wang Mo Chu Guanjun Zhang Ligang Zhang China University of Mining and Technology (Beijing) D11 Xueyuan Road Haidian District Beijing 100083 China China Datang Corporation Science and Technology Research Institute Beinong Road 2 Changping District Beijing China School of Materials Science and Engineering Central South University Changsha 410083 Hunan China

The harmful trace elements will be released during coal utilization, which can cause environment pollution and further endangering human health, especially for heavy metal elements. Compared to combustion, the release of heavy metal elements during coal pyrolysis process, as a critical initial reaction stage of combustion, has not received sufficient attention. In the present paper, a low rank coal, from Xinjiang province in China, was pyrolyzed in a fixed bed reactor from room temperature, at atmospheric pressure, with the heating rate of 10 °C/min, and the final pyrolysis temperature was from 400 to 800℃ with the interval of 100℃. The volatility of heavy metal elements (including As, Hg, Cd and Pb) during pyrolysis process was investigated. The results showed the volatility of all heavy metal elements increased obviously with increasing temperature, and followed the sequence as Hg > Cd > As > Pb, which was mainly caused by their thermodynamic property and occurrence modes in coal. The occurrence modes of heavy metals were studied by sink-andfloat test and sequential chemical extraction procedure, and it can be found that the heavy metal elements were mainly in the organic and residual states (clay minerals) in the raw coal. And most of the organic heavy metals escaped during the pyrolysis process, the remaining elements were mainly in the residual state, and the elements in Fe-Mn state also tended to remain in the char.
