| 1 | Motion behavior of particles in air-solid magnetically stabilized fluidized beds for separation显示文摘In order to study the settling mechanism of particles in an air-solid magnetically stabilized fluidized bed(MSFB) for separation,we carried out free settling and quasi-zero settling tests on the tracing particles.The results show that the main resistance forces as the tracing particles settled in an air-solid MSFB were motion resistance force and yield force.The motion resistance and yield forces greatly hindered the free settling of the particles by greatly decreasing the acceleration for settling process of the particles.The acceleration decreased from 3022.62 cm/s 2 to zero in 0.1 s,and in the end,the particles stopped in the air-solid MSFB.The yield force on particles increased with increasing the magnetic field intensity,resulting in decrease of the quasi-zero settling displacement.However,the yield force on particles decreased with increasing the fluidized air velocity,leading to increase of the quasi-zero settling displacement.When the structure and operating parameters of the air-solid MSFB were set up,the yield stress on particles stopped in an air-solid MSFB was a function of diameter and density of particles.The settling displacements of equal diameter particles increased with increasing their densities,and the settling displacements of equal density particles increased with increasing their diameters. | Song Shulei a,,Zhao Yuemin a,Luo Zhenfu a,Tang Ligang b a School of Chemical Engineering and Technology,China University of Mining & Technology,Xuzhou 221116,China b Coal Mining and Designing Department,Tiandi Science & Technology Company Co.Ltd.,Beijing 100013,China | 2012 | International Journal of Mining Science and Technology2012，22，5： | 13 |
| 2 | New progress in the processing and efficient utilization of coal显示文摘Coal accounts for about 70% of the primary energy sources in China.The environmental pollution and resources waste involved with coal processing and utilization are serious.It is therefore urgent to develop highly-efficient coal resources utilization theory and methods with low-carbon discharge.Based on our long-term basic research and technology development,the progress in beneficiation,cleaning,and transformation of coal,which includes dense phase fluidized bed dry beneficiation,deep screening of wet fine coal,micro-bubble fiotation column separation,molecular coal chemistry,and transformation and separation of coal and its derivatives into value-added chemicals under mild conditions,is discussed. | Zhao Yuemin Liu Jiongtian wei xianyong Luo Zhenfu Chen Qingru Song Shulei | 2011 | Mining Science and Technology2011，21，4： | 9 |
| 3 | Development of a multiplex one-step real-time RT-PCR assay for the simultaneous detection of eight viruses associated with febrile rash illnesses显示文摘Fever and rash illnesses(FRIs)are a series of common diseaseswith fever and rashes as clinicalmanifestations,most of which are caused by viral infection.The rashes of FRIs are generally nonspecific;therefore it is difficult to identify FRIassociated viruses solely based on clinical symptoms.To achieve rapid and accurate identification of FRI pathogens,a multiplex one-step real-time reverse transcription-polymerase chain reaction(RT-PCR)assay was developed and evaluated in this study.Primers and probes were selected for the detection of measles virus(MeV),rubella virus(RV),human enterovirus(EV),varicella-zoster virus(VZV),dengue virus(DENV),human parvovirus B19(B19),Epstein-Barr virus(EBV),and human herpes virus 6(HHV-6),which cover the most common pathogenic viruses of FRIs.Detection of the eight FRI-associated viruses,which was divided into two groups/tubes,was simultaneously performed under universal optimized reaction conditions in multiplex one-step real-time RT-PCR assay.The multiplex realtime RT-PCR showed high sensitivity and specificity in detecting the eight FRI-associated viruses.The limits of detection(LODs)for the eight viruses were in the range of 47–177 copies/reaction,and no cross reactions for the eight FRIassociated viruses were found in the multiplex assay.In addition,the results of the multiplex real-time RT-PCR assay were consistent with the results of a monoplex real-time RT-PCR assay and sequencing for clinical specimens obtained from FRI patients.With its advantages of high efficiency and rapid and accurate diagnosis,multiplex real-time RT-PCR was very feasible for the early diagnosis of FRI pathogenic viruses and would be of great help for the proper treatment,monitoring,and initiation of preventive measures for FRI cases. | Aili Cui Shulei Wang Qiang Zhang Huiling Wang Zhen Zhu Aqian Li Qinqin Song Yanzhe Hao Jilan He Wenbo Xu Yan Zhang | 2020 | Biosafety and Health2020，2，2： | 5 |
| 4 | Effects of sintered metal distributor on fluidization quality of the air dense medium fluidized bed显示文摘Dry coal beneficiation using an air dense medium fluidized bed (ADMFB) requires the formation of a sta- ble and uniform bed from the dense medium. Others have shown that the structure and geometric parameters of the air distributor have a significant influence on the experimentally observed fluidization quality. In this study we used a sintered metal distributor (SMD) in the ADMFB separator and study its effect on the fluidization quality. The results show that for the same open area ratio (OAR), a smaller aper- ture in the SMD will provide improved fluidization quality. If aperture size is held constant bigger open area ratios result in improved fluidization quality. And, the fluidization quality also improves when the pressure drop across the SMD increases. A model relating distributor pressure drop and the geometric parameters of the SMD is also proposed. | Yang Xuliang Zhao Yuemin Luo Zhenfu Chen Zengqiang Song Shulei | 2011 | Mining Science and Technology2011，21，5： | 4 |
| 5 | Progress in developments of dry coal beneficiation显示文摘China’s energy supply heavily relies on coal and China’s coal resource and water resource has a reverse distribution.The problem of water shortages restricts the applications of wet coal beneficiation technologies in drought regions.The present situation highlights the significance and urgency of developing dry beneficiation technologies of coal.Besides,other countries that produce large amounts of coal also encounter serious problem of lack of water for coal beneficiation,such as American,Australia,Canada,South Africa,Turkey and India.Thus,dry coal beneficiation becomes the research hot-points in the field of coal cleaning worldwide in recent years.This paper systematically reviewed the promising research efforts on dry coal beneficiation reported in literature in last 5 years and discussed the progress in developments of dry coal beneficiation worldwide.Finally,we also elaborated the prospects and the challenges of the development of dry coal beneficiation. | Yuemin Zhao Xuliang Yang Zhenfu Luo Chenlong Duan Shulei Song | 2014 | International Journal of Coal Science & Technology2014，1，1： | 3 |
| 6 | Eutectic effect during mesophase formation in co-carbonization of ethylene tar pitch and polystyrene显示文摘Ethylene tar pitch was co-carbonized with waste polystyrene to prepare mesophase pitch.The characteristics of mesophase pitches were examined using polarized light optical microscopy,apparent viscometry,Fourier transform infrared spectrometry,1H nuclear magnetic resonance spectrometry,and X-ray diffractometry.The properties of the mesophase pitch were greatly improved because of the eutectic effect.The soluble content increased from 5% to 56%,the mesophase itself increased from 32% to 100%,and the optical texture was changed from a coarse mosaic into a flow domain after the waste polystyrene was added to the ethylene tar pitch.The apparent viscosity showed that the mesophase pitch changed from thixotropic to Newtonian suggesting improved rheological behavior during co-carbonization.The increased number of alkyl groups,which are mainly methylene groups,altered the molecular structure of the mesophase pitch in a way that resulted in the eutectic effect. | Cheng Xianglin Song Shulei | 2012 | International Journal of Mining Science and Technology2012，22，2： | 2 |

| 8 | Occurrence characteristics of mercury in high-mercury coal and distribution rule of mercury in products of an air dense medium fluidized bed显示文摘Mercury emitted from direct combustion of high-mercury coal does great harm to the environment. To make good use of high-mercury coal, it is necessary to study the occurrence characteristics of mercury in coal and high-efficient methods of mercury removal. In this paper, high-mercury coal of Guizhou Province of China was taken as an object to study the nature of mercury in coal and the rule of mercury removal by dry preparation method. Mercury mainly distributes in the medium and high density fractions, and has a good affinity with silicon, aluminum, iron, titanium, potassium, calcium, zinc, sodium and magnesium. It exists in minerals formed by these elements and presents significant correlation with ash in coal. After the high-mercury coal is separated by air dense medium fluidized bed, mercury content of clean coal is reduced to 1/10 of raw coal, while mercury content of gangue is increased to 3 times that of raw coal. This indicates that mercury in raw coal is rejected greatly by ADMFB and enriched in highdensity fractions. The rates of ash removal and mercury removal decrease with the density and present a very high correlation. | Guilin Zhang Shulei Song Weiqiao Yang Bo Zhang Jianqing Wang | 2018 | International Journal of Mining Science and Technology2018，28，6： | 1 |
