| 1 | Simultaneous oxidation of NO,SO_2 and Hg^0 from flue gas by pulsed corona discharge显示文摘A process capable of simultaneously oxidizing NO,SO2,and Hg0 was proposed,using a high-voltage and short-duration positive pulsed corona discharge.By focusing on NO,SO2,and Hg0 oxidation effciencies,the influences of pulse peak voltage,pulse frequency,initial concentration,electrode number,residence time and water vapor addition were investigated.The results indicate that NO,SO2 and Hg0 oxidation effciencies depend primarily on the radicals(OH,HO2,O) and the active species(O3,H2O2,etc.) produced by the pulsed corona discharge.The NO,SO2 and Hg0 oxidation effciencies could be improved as pulse peak voltage,pulse frequency,electrode number and residence time increased,but they were reduced with increasing initial concentrations.By adding water vapor,the SO2 oxidation effciency was improved remarkably,while the NO oxidation effciency decreased slightly.In our experiments,the simultaneous NO,SO2,and Hg0 oxidation effciencies reached to 40%,98%,and 55% with the initial concentrations 479 mg/m3,1040 mg/m3,and 15.0 μg/m3,respectively. | XU Fei,LUO Zhongyang,CAO Wei,WANG Peng,WEI Bo,GAO Xiang,FANG Mengxiang,CEN Kefa State key Laboratory of Clean Energy Utilization,Zhejiang University,Hangzhou 310027,China. | 2009 | Journal of Environmental Sciences2009，21，3： | 22 |
| 2 | Emission characteristics of dioxins,furans and polycyclic aromatic hydrocarbons during fluidized-bed combustion of sewage sludge显示文摘Pre-dried sewage sludge with high sulfur content was combusted in an electrically heated lab-scale fluidized-bed incinerator. The emission characteristics of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polycyclic aromatic hydrocarbons (PAHs) were studied. Coal and calcium oxide (CaO) were added during the sewage sludge combustion tests to optimize combustion conditions and control SO2 emission. The results indicated that the flue gases emitted during mono-combustion of sewage sludge were characterized by relatively high concentrations of SO2, NOx and organic pollutants, due to the high sulfur, nitrogen, and volatile matter content of sewage sludge. The total 16 USEPA priority PAHs and 2,3,7,8-substituted PCDD/Fs produced from sewage sludge combustion were found to be 106.14 μg/m3 and 8955.93 pg/m3 in the flue gas, respectively. In the case of co- combustion with coal (msludge/mcoal = 1:1), the 16 PAHs and 2,3,7,8-substituted PCDD/Fs concentrations were markedly lower than those found during mono-combustion of sewage sludge. During co-combustion, a suppressant effect of CaO on PCDD/Fs formation was observed. | DENG Wenyi, YAN Jianhua, LI Xiaodong, WANG Fei, CHI Yong, LU ShengyongState Key Laboratory of Clean Energy Utilization, Institute for Thermal Power Engineering, Zhejiang University, Hangzhou 310027, China. | 2009 | Journal of Environmental Sciences2009，21，12： | 17 |
| 3 | Effect of temperature and oxygen on the formation of chlorobenzene as the indicator of PCDD/Fs显示文摘Sampling and analysis of polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs) are both time-consuming and expensive. In principle,real-time monitoring of chlorobenzene(CBz) as an indicator for PCDD/Fs could be useful to control and optimize incinerator operating conditions.To test this strategy,CBz was analyzed together with PCDD/Fs in flue gas samples collected from a hospital waste incinerator.Moreover,lab experiments were conducted to investigate the eect of temperature and oxygen on CBz formation from fly ash from the same incinerator.The experimental results demonstrate that chlorobenzene(in particular PeCBz) correlate well with PCDD/Fs,in line with previous research.The optimum temperature of CBz formation is in a range of 350 to 400°C and CBz yield increases significantly with oxygen,in line with PCDD/Fs formation.This study is useful for confirming the de novo mechanism and defining correlations between CBz and PCDD/Fs. | Mi Yan,Xiaodong LiTong Chen,Shengyong Lu,Jianhua Yan,Kefa Cen State Key Laboratory of Clean Energy Utilization,Zhejiang University,Hangzhou 310027,China | 2010 | Journal of Environmental Sciences2010，22，10： | 16 |
| 4 | Mechanochemical decomposition of pentachlorophenol by ball milling显示文摘The mechanochemical dechlorination of pentachlorophenol (PCP) was studied using CaO and SiO2 powder as additives. The effects of the milling time and additives on the dechlorination rate were investigated. The resulting product was characterized by X-ray diffraction (XRD), Fourier transform infrared spectra (FT-IR), thermogravimetric analysis (TG) and ion chromatography (IC). It is found that grinding operation could dechlorinate PCP, with the formation of inorganic chloride and amorphous carbon. The addition of quartz to the grinding mixture facilitated dechlorination. On the basis of the experimental results, the decomposition mechanism was proposed. Decomposition predominantly proceeds through rupture of C-Cl bond in PCP molecule, followed by the formation of inorganic chlorides. | WEI Yinglei, YAN Jianhua, LU Shengyong, LI XiaodongState Key Laboratory of Clean Energy Utilization, Zhejiang University, Hangzhou 310027, China. | 2009 | Journal of Environmental Sciences2009，21，12： | 11 |
| 5 | Estimation of methane and nitrous oxide emissions from biomass waste in China:A case study in Hebei Province显示文摘Crop residue,animal manure and MSW are selected as representative biomass waste.Greenhouse gas emissions from treatment and disposal process of biomass waste in Hebei province are estimated for the period from 2002 to 2007,using the methodologies recommended by the Intergovernmental Panel on Climate Change.Greenhouse gas emission was about 10 Mt CO2-equivalent annually.About 6% of greenhouse gas emission came from open burning of crop residue,74% from management system of animal manure,and 20% from MSW disposal.Among all the greenhouse gas sources,landfill is the most concentrated one,and has significant potential of emission reduction. | LUO YuXiang1,WANG Wei1,WAN Xiao2,DENG Zhou2 & ZHU CuiPing2 1 Department of Environmental Science and Engineering,Tsinghua University,Beijing 10084,China 2 J&K China Cleaning Energy Technology Company Limited,Beijing 100085,China | 2010 | Science China(Technological Sciences)2010，53，1： | 6 |

| 8 | Numerical investigation of the effect of sub-grid scale eddies on the dispersed particles by LES/FDF model显示文摘An LES/FDF model was developed by the authors to investigate the SGS effect on the particle motion in the gas-particle two-phase plane wake flow.The simulation results of dispersion rate for different particles were compared with the results without using the FDF model.It was shown that the large eddy structure is the dominant factor influencing the particle diffu-sion in space for small particles(small Stokes-number particles),but for intermediate or large diameter particles,the influence of the sub-grid scale eddies on the dispersion rate is in the same order as that of the large eddies.The sub-grid scale eddies increase the particle dispersion rate in most time,but sometimes they decrease the dispersion rate.The sub-grid scale particle dispersion rate is decided not only by the intensity of sub-grid scale eddies and the Stokes number of the particles,but also by the large eddy structure of the flow field.For the particles in isotropic turbulence,the dispersion rate decreases as the particle diameter increases. | JIN HanHui1,CHEN SuTao1,CHEN LiHua1 & FAN JianRen2 1 School of Aeronautics and Astronautics,Zhejiang University,Hangzhou 310027,China 2 State Key Lab of Clean Energy Utilization,Zhejiang University,Hangzhou 310027,China | 2010 | Science China(Technological Sciences)2010，53，5： | 3 |
| 9 | Catalytic Performance and Texture of TEOS Based Cu/SiO_2 Catalysts for Hydrogenation of Dimethyl Oxalate to Ethylene Glycol显示文摘Highly active and selective Cu/SiO2 catalysts for hydrogenation of dimethyl oxalate(DMO) to ethylene glycol(EG) were successfully prepared by means of a convenient one-pot synthetic method with tetraethoxysi lane(TEOS) as the source of silica. XRD, H2-TPR, SEM, TEM, XRF and N2 physisorption measurements were performed to characterize the texture and structure of Cu/SiO2 catalysts with different copper loadings. The active components were highly dispersed on SiO2 supports. Furthermore, the coexistence of Cu0 and Cu+ contributed a lot to the excellent performance of Cu-TEOS catalysts. The DMO conversion reached 100% and the EG selectivity reached 95% at 498 K and 2 MPa with a high liquid hourly space velocity over the 27-Cu-TEOS catalyst with an actual cop per loading of 19.0%(mass fraction). | WANG Shu-rong, YIN Qian-qian and LI Xin-bao State Key Laboratory of Clean Energy Utilization, Zhejiang University, Hangzhou 310027, P.

| 10 | Research of the Gas-solid Flow Character Based on the DEM Method显示文摘Numerical simulation of gas-solid flow behaviors in a rectangular fluidized bed is carried out three dimensionally by the discrete element method (DEM).Euler method and Lagrange method are employed to deal with the gas phase and solid phase respectively.The collided force among particles,striking force between particle and wall,drag force,gravity,Magnus lift force and Saffman lift force are considered when establishing the mathematic models.Soft-sphere model is used to describe the collision of particles.In addition,the Euler method is also used for modeling the solid phase to compare with the results of DEM.The flow patterns,particle mean velocities,particles' diffusion and pressure drop of the bed under typical operating conditions are obtained.The results show that the DEM method can describe the detailed information among particles,while the Euler-Euler method cannot capture the micro-scale character.No matter which method is used,the diffusion of particles increases with the increase of gas velocity.But the gathering and crushing of particles cannot be simulated,so the energy loss of particles' collision cannot be calculated and the diffusion by using the Euler-Euler method is larger.In addition,it is shown by DEM method,with strengthening of the carrying capacity,more and more particles can be schlepped upward and the dense suspension upflow pattern can be formed.However,the results given by the Euler-Euler method are not consistent with the real situation. | Xueyao Wang and Yunhan Xiao Research Center for Clean Energy and Power,Chinese Academy of Sciences Key Laboratory of Advanced Energy and Power,Chinese Academy of Sciences (Institute of Engineering Thermophysics),Beijing,100190,China | 2011 | Journal of Thermal Science2011，20，6： | 2 |
| 11 | Method for determining effective flame emissivity in a rotary kiln incinerator burning solid waste显示文摘Temperature is the most important parameter for the improvement of combustion efficiency and the control of pollutants.In order to obtain accurate flame temperatures in a rotary kiln incinerator using non-intrusive thermographic method,the effective flame emissivity was studied.A combined narrow-and wide-band model and Mie scattering method were used to calculate the radiative properties for gases and fly-ash particles under different combustion conditions.The effects of the air/waste ratio and fly-ash particles on the effective flame emissivity were discussed.The results of numerical calculations showed that the effective emissivity decreased from 0.90 to 0.80 when the air/waste ratio increased from 1.0 to 1.8,and the effect of the fly-ash particles was ignorable under the conditions discussed in this paper.Experimental measurement results indicated that the accuracy of the thermographic temperature measurements improved significantly if the setting of the flame emissivity was adjusted according to the air/waste ratio. | Jin-cai DU1,2,Qun-xing HUANG1,Jian-hua YAN1 (1State Key Laboratory of Clean Energy Utilization,Zhejiang University,Hangzhou 310027,China) (2School of Aeronautics and Astronautics,Zhejiang University,Hangzhou 310027,China) | 2012 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2012，13，12： | 2 |
| 12 | Energy recovery and abatement potential of CO_2 emissions for an integrated iron and steel making enterprise显示文摘The typical features for an integrated iron & steelmaking industry are high energy consumption and CO2 emission.The traditional BF-BOF process in an integrated Iron and steelmaking enterprise produces a large amount of residual heat and energy,which has great potential for recovery and abatement potential of CO2 emissions.In this paper,for an integrated Iron & steelmaking enterprise of 10 million tons per year in capacity,the residual heat and energy recovery analysis was conducted.It is indicateded that the residual heat and energy can be recovered as electric power by using present advanced process technology.By means of the distributed power generation,the residual heat and energy can be recovered,with a power generation capacity of 419.5 kWh per ton steel product.Accordingly,the abatement potential of CO2 emissions for an integrated iron & steel making enterprise was also evaluated,which indicated that about 398.5 kg CO2 could be reduced per ton steel product. | LI HongFu1,2,BAO WeiJun3,LI HuiQuan3 & CANG DaQiang1 1 Ecology and Recycling Metallurgy Laboratory,Ministry of Education,School of Metallurgical and Ecological Engineering,University of Science and Technology Beijing,Beijing 10083,China 2 Jinan iron & Steel Group Ltd.,Jinan 250101,China 3 National Engineering Laboratory for Clean Production Technology of Hydrometallurgy,Institute of Process Engineering,Chinese Academy of Sciences,Beijing 100190,China | 2010 | Science China(Technological Sciences)2010，53，1： | 2 |

| 14 | Biogas recovery from microwave heated sludge by anaerobic digestion显示文摘Biogas generated from sewage sludge,livestock waste,and food waste by anaerobic digestion is a valuable renewable energy resource.However,conventional anaerobic digestion is not an efficient process.A long hydraulic retention time and low biogas recovery rate hinder the applications of those resources.An effective pretreatment method to destroy sludge microbial cells has been one of the major concerns regarding improvement of the biogas production.This article focuses on the effects of microwave heating on sludge anaerobic digestion.Volatile suspended solid(VSS) and chemical organic demand solubilization of heated sludge were investigated.Microwave heating was found to be a rapid and efficient process for releasing organic substrates from sludge.The increase of organic dissolution ratio was not obvious when holding time was over 5 min with microwave heating.The effect of the VSS solubilization was primarily dependent on heating temperature.The highest value of VSS dissolving ratio,36.4%,was obtained at 170°C for 30 min.The COD dissolving ratio was about 25% at 170°C.Total organic carbon of treated sludge liquor was 1.98 and 2.73 g/L at 150°C and 170°C for 5 min,respectively.A biochemical methane potential(BMP) test of excess sludge and a mixture of primary and excess sludge demonstrated an increase in biogas production.The total biogas from microwave treated mixture sludge increased by 12.9% to 20.2% over control after 30 days of digestion.Biogas production was 11.1% to 25.9% higher for excess sludge than for untreated sludge.The VS removal ratios of mixture sludge and excess sludge were 12% and 11% higher,respectively,compared to the untreated sludge. | QIAO Wei1,WANG Wei2,ZHU CuiPing3 & ZHANG ZhongZhi1 1 College of Chemical Science and Engineering,China University of Petroleum,Beijing 102249,China 2 Department of Environmental Science and Engineering,Tsinghua University,Beijing 10084,China 3 J & K China Cleaning Energy Technology Co.Ltd.,Beijing 100085,China | 2010 | Science China(Technological Sciences)2010，53，1： | 1 |
