Effect of Biochar as Reductant on Magnetizing-roasting Behavior of Pyrite Cinder

引用

Journal of Iron and Steel Research International 2015年第5期22卷 371-376页

作者： Xiao-hui FAN Qiong DENG Min GAN hai-bo wang School of Minerals Processing and Bioengineering Central South University

The effect of biochar substituted for anthracite as reductant on magnetizing-roasting pyrite cinder was in- vestigated. The key of magnetizing-roasting is the gasification reaction between reductants and CO2. Since biochar could react with CO2 more rapidly at lower temperature, the reactivity of biochar is better than that of anthracite. The gasification of biochar could produce reducing condition of φco/（φco--φco2 ） about 10 %- 20 % between 700-- 800 ℃, which is in accord with the atmosphere and temperature of Fe2 O3 reduction. So it is beneficial to the reduc- tion of iron mineral of pyrite cinder. Compared with anthracite, bioehar could decrease the roasting temperature from 825 to 750 ℃ and roasting time from 20 to 15 min, which shows that a better effect of magnetization could be ob- tained in the condition of lower temperature and shorter time. Using biochar as reductant, iron concentrate extracted from pyrite cinder as about 64% iron grade could be produced, and the recovery is over 90% under the condition of above 90% grinding particle less than 0. 045 mm and magnetic intensity of 0. 124--0. 194 T.

ab initio Studies on Molecular Conductor (BEDSe-TTF)2[Fe(CN)5NO]

Communications in Theoretical Physics 2001年第12期36卷 729-732页

作者： YAO Kai-Lun TU hai-bo wang Wei-Zhong Physics Department and State Key Laboratory of Laser Technology Huazhong University of Science and Technology Wuhan 430074 China International Center for Materials Physics The Chinese Academy of Sciences Shenyang 110015 China Physics Department and State Key Laboratory of Laser Technology Huazhong University of Science and Technology Wuhan 430074 China Physics Department and State Key Laboratory of Laser Technology Huazhong University of Science and Technology Wuhan 430074 China

In this paper the ab initio study using pseudopotential plane wave method with the local spin density functional approximation is presented for the molecular conductor (BEDSe-TTF)2[Fe(CN)5NO]. The mean electronic density distributions are obtained, and we find that the extended π orbital of the selenium does not affect the properties of material as assumed in other papers and the "side-by-side" type S...S interaction is the primary interaction between donors. From band structure calculations we analyze the influence of the NO groups on the electronic structure and magnetic properties of molecule. It is shown that the itinerant electrons important to electronic properties in these types of hybrids are delocalized electrons contributed by NO groups, instead of by the 3d electrons of Fe. Additionally, we have found that the localized magnetic moment is also contributed by the NO groups in this molecular conductor. From total energy calculations the molecular structure with the lowest energy is found due to the interaction between split spins, and the particular positions of the NO groups are obtained.

Preparation of SiC_p/Al_2O_3-Al Composites by Directed Metal Oxidation

引用

Chinese Journal of Aeronautics 2006年第B12期19卷 47-50页

作者： LIN Ying YANG hai-bo wang Fen ZHU Jian-feng School of Materials Science and Engineering Shaanxi University of Science ＆ Technology Xianyang 712081 China

SiCp/Al2O3-Al composites were synthesized by means of direct metal oxidation method. The composition and microstructures of the composites were investigated using X-ray diffraction （XRD）, scanning electron microscopy （SEM） and metallurgical microscope. The effects of technical parameters on the properties of the product were analyzed. The results indicate that the composite possesses a dense microstructure, composed of three interpenetrated phases. Of them, SiO2 layer prohibits the powdering of the composites; Mg promotes the wetting and infiltration of the system and Si restricts the interfacial reaction while improving the wetting ability between reinforcement and matrix.

作者： hai bo wang Ping An wang Quan Jun wang Xiao Li Sun Lin Lin Jing Department of Chemistry School of Pharmacy Fourth Military Medical University Xi＇an 710032 China

An efficient synthesis of cinchona alkaloid-derived ligands based on solvent-free microwave-assisted reaction was described. The coupling of 1,4-dichlorophthalazine or 3,6-dichloropyridazine with quinine, cinchonine or cinchonidine provide bis-or monocinchona alkaloid-derived ligands in moderate to good yields （52-89%） within 15 min under optimum microwave conditions.

Influence of aluminium nitride as a foaming agent on the preparation of foam glass-ceramics from high-titanium blast furnace slag

引用

International Journal of Minerals,Metallurgy and Materials 2016年第5期23卷 595-600页

作者： Huan Shi Ke-qin Feng hai-bo wang Chang-hong Chen Hong-ling Zhou School of Manufacturing Science and Engineering Sichuan University Chengdu 610065 China School of Materials Engineering Panzhihua College Panzhihua 617000 China

To effectively reuse high-titanium blast furnace slag （TS）, foam glass-ceramics were successfully prepared by powder sintering at 1000℃. TS and waste glass were used as the main raw materials, aluminium nitride （AIN） as the foaming agent, and borax as the fluxing agent. The influence of the amount of A1N added （lwt%-5wt%） on the crystalline phases, microstructure, and properties of the produced foam glass-ceramics was studied. The results showed that the main crystal phases were perovskite, diopside, and augite. With increasing A1N content, a transformation from diopside to augite occurred and the crystallinity of the pyroxene phases slightly decreased. Initially, the aver- age pore size and porosity of the foam glass-ceramics increased and subsequently decreased; similarly, their bulk density and compressive strength decreased and subsequently increased. The optimal properties were obtained when the foam glass-ceramics were prepared by adding 4wt% AIN.

Comparison of the Contributions of Tetrahydrofurfuryl Alcohol and PEG to a-Chymotrypsin Renaturation with High Performance Hydrophobic Interaction Chromatography

引用

Chinese Chemical Letters 2003年第3期14卷 294-297页

作者： Ye Hua SHEN hai bo wang Quan BAI Xin Du GENG 中国人民解放军85医院，上海200052

The contributions of tetrahydrofurfuryl alcohol (THFA) and polyethylene glycol (PEG) to the renatured efficiency of a-chymotrypsin were investigated and compared with each other. The maximum increments of bioactivity recovery of a-Chy were found to be 25.1% for THFA, 10.4% for PEG, respectively. The experimental results indicated that the denaturant solution containing THFA contributed more to the renaturation of a-Chy in high performance hydrophobic interaction chromatography (HPHIC) than that containing PEG, when the concentration of THFA was 3.2%, the bioactivity recovery of a-Chy is the highest.
