| 1 | Study on the recovery of hydrogen from refinery (hydrogen+methane) gas mixtures using hydrate technology显示文摘A novel technique for separating hydrogen from (H2 + CH4) gas mixtures through hydrate formation/dissociation was proposed. In this work, a systematic experimental study was performed on the separation of hydrogen from (H2 + CH4) feed mixtures with various hydrogen contents (mole fraction x = 40%-90%). The experimental results showed that the hydrogen content could be enriched to as high as ~94% for various feed mixtures using the proposed hydrate technology under a temperature slightly above 0℃ and a pressure below 5.0 MPa. With the addition of a small amount of suitable additives, the rate of hydrate formation could be increased significantly. Anti-agglomeration was used to disperse hydrate particles into the condensate phase. Instead of preventing hydrate growth (as in the kinetic inhibitor tests), hydrates were allowed to form, but only as small dispersed particles. Anti-agglomeration could keep hydrate particles suspended in a range of condensate types at 1℃ and 5 MPa in the water-in-oil emulsion. | WANG XiuLin CHEN GuangJin YANG LanYing ZHANG LinWei | 2008 | Science China Chemistry2008，51，2： | 17 |
| 2 | Relationship between petroleum hydrocarbon and plankton in a mesocosm experiment显示文摘A mesocosm experiment was carried out from May 26 to June 1, 1998 at the location of 30’52’N, 122’36’E, the Changjiang Estuary, in order to measure the influence of petroleum hydrocar- bon to the ecosystem, furthermore, to estimate the environmental capacity. In the experiment, it is found that the petroleum hydrocarbon can, in some degree, enhance the growth of diatom, but inhibit the growth of dinoflagellate. In general, the petroleum hydrocarbon can inhibit the growth of both Phytoplankton and zooplankton, and can the inhibit the growth of total plankton (including phytoplankton and zooplankton) as well. A kinetic model was presented to estimate the uptake/release rate constants of petroleum hydrocarbon by plankton, and thereafter, the uptake and release rate constants (k1, k2), bioconcentration factor (BCF) as well as the petroleum bydrocarbon influenced influenced uptake and release rate constants of nutrients by phytoplankton (kup, krel) were obtained. The results imply that the bioconcentration of petroleum hydrocarbon by plankton is fairly large and petroleum hydrocarbon caused no significant influence on the uptake of N- NO3, but significant influence on that of P -PO4. In addition, the application of kinetic model for the bioconcentration of volatile organic toxic compound by organism suggests that the uptake of petroleum hydrocarbon by plankton was an important process for the environmental capacity of petroleum hydrocarbon. | Shi Xiaoyong, Wang Xiulin, Han Xiurong, Jiang Yu Zhu Mingyuan, Chen Shang, Koshikawa Hiroshi (1.

| 3 | Nutrient composition and distributions in coastal waters impacted by the Changjiang plume显示文摘Four cruises were conducted during 2002-2003 in the Changjiang Estuary and adjacent coastal areas. The data presented show a clear coast to open sea gradient in nutrients related to the river inputs. Maximum values of chlorophyll a were typically observed at intermediate salinities at surface water and coincided with non-conservative decreases in nutrients along the salinity gradient,indicating that removal of nutrients was related to phytoplankton uptake. The seasonal variations of nutrient concentrations were just opposite to those of chlorophyll a,indicating that the seasonal variations of nutrients were mainly controlled by phytoplankton uptake,whereas riverine inputs merely weakened or balanced its extent. During the estuarine mixing,phosphate demonstrated some remobilization during all the four cruises; whereas both conservative and non-conservative behaviors for dissolved inorganic nitrogen and silicate were observed in the study area,indicating that both biotic and abiotic events may affect their behaviors during the estuarine mixing. Under the influence of freshwater inputs with high value of ratio of nitrogen to phosphorus,the estuarine and coastal waters impacted by the Changjiang plume were high (>30) in ratio of nitrogen to phosphorus,but rates of primary production were apparently not constrained by any kind of nutrient elements. However,the low (<1) ratio of silicate to nitrogen in most of the study area might be linked with the rapidly increasing frequency of harmful algal bloom(HAB) incidents in recent years in the coastal waters impacted by the Changjiang plume. | WANG Xiulin WANG Baodong ZHANG Chuansong SHI Xiaoyong ZHU Chenjian XIE Linping HAN Xiurong XIN Yu WANG Jiangtao | 2008 | Acta Oceanologica Sinica2008，27，5： | 7 |
| 4 | Seasonal Changes in Phytoplankton Biomass and Dominant Species in the Changjiang River Estuary and Adjacent Seas:General Trends Based on Field Survey Data 1959-2009显示文摘The characteristics of seasonal variation in phytoplankton biomass and dominant species in the Changjiang River Estuary and adjacent seas were discussed based on field investigation data from 1959 to 2009. The field data from 1981 to 2004 showed that the Chlorophyll-a concentration in surface seawater was between 0.4 and 8.5 μg dm-3. The seasonal changes generally presented a bimodal trend, with the biomass peaks occurring in May and August, and Chlorophyll-a concentration was the lowest in winter. Seasonal biomass changes were mainly controlled by temperature and nutrient levels. From the end of autumn to the next early spring, phytoplankton biomass was mainly influenced by temperature, and in other seasons, nutrient level(including the nutrient supply from the terrestrial runoffs) was the major influence factor. Field investigation data from 1959 to 2009 demonstrated that diatoms were the main phytoplankton in this area, and Skeletonema costatum, Pseudo-nitzschia pungens, Coscinodiscus oculus-iridis, Thalassinoema nitzschioides, Paralia sulcata, Chaetoceros lorenzianus, Chaetoceros curvisetus, and Prorocentrum donghaiense Lu were common dominant species. The seasonal variations in major dominant phytoplankton species presented the following trends: 1) Skeletonema(mainly S. costatum) was dominant throughout the year; and 2) seasonal succession trends were Coscinodiscus(spring) →Chaetoceros(summer and autumn) → Coscinodiscus(winter). The annual dominance of S. costatum was attributed to its environmental eurytopicity and long standing time in surface waters. The seasonal succession of Coscinodiscus and Chaetoceros was associated with the seasonal variation in water stability and nutrient level in this area. On the other hand, long-term field data also indicated obvious interannual variation of phytoplankton biomass and community structure in the Changjiang River Estuary and adjacent seas: average annual phytoplankton biomass and dinoflagellate proportion both presented increased trends during the 1950 s-2000 s. | YANG Shu HAN Xiurong ZHANG Chuansong SUN Baiye WANG Xiulin SHI Xiaoyong | 2014 | Journal of Ocean University of China2014，13，6： | 7 |
| 5 | Calculation methodology of marine environmental capacity for heavy metal:A case study in Jiaozhou Bay,China显示文摘Results from past pollution control practices show that environmental quality can be ensured by controlling the actual amount of pollutants formed in the environment.Therefore,the marine environmental capacity for heavy metals was introduced.Marine environmental capacity for heavy metals is defined as the maximum amount of heavy metals permitted in the marine environment system to preserve the benign cycle of materials in the oceansphere,and to limit the adverse effects of heavy metals on the biosphere,hydrosphere,atmosphere,and lithosphere.Based on the box or three-dimensional model in the target coastal region,including the self-purification and output of heavy metals,the marine environmental capacity for heavy metals can be calculated within a given criterion and time.In this study,a method was proposed to calculate the marine environmental capacity for heavy metals which includes four steps:(1) gathering the basis information of target coastal ecosystem,(2) selection of water control points and water quality criteria for these points,(3) development of numerical models for the biogeochemical cycling of heavy metals in target coastal region,and(4) calculation of environmental capacity using the developed model.According to the proposed method,the marine environmental capacity for lead is approximately 60 tons per year if Grade I seawater quality is set as the control criterion in Jiaozhou Bay.An effective seawater quality management plan can also be framed based on the environmental capacity for metals. | LI KeQiang WANG XiuLin | 2013 | Chinese Science Bulletin2013，58，2： | 7 |
| 6 | Influential factors and control of water inrush in a coal seam as the main aquifer显示文摘In this paper, a combination of field measurement, theoretical analysis and numerical simulation were used to study the main control factors of coal mine water inrush in a main aquifer coal seam and its control scheme. On the basis of revealing and analyzing the coal seam as the main aquifer in western coal mine of Xiao Jihan coal mine, the simulation software of PHASE-2D was applied to analyze the water inflow under different influencing factors. The results showed that water inflow increases logarithmically with the coal seam thickness, increases as a power function with the permeability coefficient of the coal seam, and increases linearly with the coal seam burial depth and the head pressure; The evaluation model for the factors of coal seam water inrush was gained by using nonlinear regression analysis with SPSS. The mine water inrush risk evaluation partition within the scope of the mining field was obtained,through the engineering application in Xiao Jihan coal mine. To ensure the safe and efficient production of the mine, we studied the coal mine water disaster prevention and control measures of a main aquifer coal seam in aspects of roadway driving and coal seam mining. | Gao Rui Yan Hao Ju Feng Mei Xianchen Wang Xiulin | 2018 | International Journal of Mining Science and Technology2018，28，2： | 6 |
| 7 | Strata behavior investigation for high-intensity mining in the water-rich coal seam显示文摘This paper describes a specific case of mining in a water-rich coal seam in western China. Water inrushes,roof caving and other disasters induced by intensive mining operation could pose great threats to the safety of coal mines. The strata behavior during the high-intensity extraction in the water-rich coal seam is analyzed by employing the numerical simulation method and in situ monitoring. The results show that about 10 m ahead of the workface, the front abutment pressure peaks is at 34.13 MPa, while the peak of the side abutment pressure is located about 8 m away from the gateway with the value of 12.41 MPa; the height of the fracture zone, the first weighting step and the cycle weighting step are calculated to be 45,50 and 20.8 m, respectively; pressure distribution in the workface is characterized by that the vertical pressure in the center occurs earlier and is stronger than those on both ends. Then, the results above are verified by in situ measurement, which may provide a basis for safe mining under similar conditions. | Ding Huande Miao Xiexing Ju Feng Wang Xiulin Wang Qingcang | 2014 | International Journal of Mining Science and Technology2014，24，3： | 6 |
| 8 | A nitrogen and phosphorus dynamic model of mesocosm pelagic ecosystem in the Jiaozhou Bay in China显示文摘A nitrogen and phosphorus dynamic model of mesocosm pelagic ecosystem was established according to the summary and synthesis of the models available,in which seven state variables (DIN,PO4-P,DON,DOP,phytoplankton,zooplankton and detritus) were included. Logically it had five modules-phytoplankton,zooplankton,dissolved inorganic nutrients,dissolved organic nutrients and detritus. The results showed that this model could simulate the variations of DIN,PO4-P,DON,DOP,POC and phytoplankton biomass in pelagic ecosystem in mesocosm properly,based on the site experiment data in the Jiaozhou Bay in the autumn of 1999 and the summer of 2000. Not only the logical structure but also the model parameters were feasible,and about 20 parameters were made to fit for the Jiaozhou Bay during the simulation. All of these are necessary to study the control mechanism of nutrients biogeochemical cycling in the Jiaozhou Bay and other China's coastal waters. | LI Keqiang WANG Xiulin LIANG Shengkang SHI Xiaoyong ZHU Chenjian CHEN Hu | 2008 | Acta Oceanologica Sinica2008，27，5： | 4 |
| 9 | Bohai crude oil identification by gas chromatogram fingerprinting quantitative analysis coupled with cluster analysis显示文摘By gas chromatogram, six crude oils fingerprinting distributed in four oilfields and four oil platforms were analyzed and the corresponding normal paraffin hydrocarbon (including pristane and phytane) concentration was obtained by the internal standard method. The normal paraffin hydrocarbon distribution patterns of six crude oils were built and compared. The cluster analysis on the normal paraffin hydrocarbon concentration was conducted for classification and some ratios of oils were used for oils comparison. The results indicated: there was a clear difference within different crude oils in different oil fields and a small difference between the crude oils in the same oil platform. The normal paraffin hydrocarbon distribution pattern and ratios, as well as the cluster analysis on the normal paraffin hydrocarbon concentration can have a better differentiation result for the crude oils with small difference than the original gas chromatogram. | SUN Peiyan BAO Mutai GAO Zhenhui LI Mei ZHAO Yuhui WANG Xinping ZHOU Qing WANG Xiulin | 2006 | Acta Oceanologica Sinica2006，25，5： | 4 |
| 10 | Environmental Capacity of Petroleum Hydrocarbon Pollutants in Jiaozhou Bay, China: Modeling and Calculation显示文摘An environmental capacity model for the petroleum hydrocarbon pollutions (PHs) in Jiaozhou Bay is constructed based on field surveys, mesocosm, and parallel laboratory experiments. Simulated results of PHs seasonal successions in 2003 match the field surveys of Jiaozhou Bay resaonably well with a highest value in July. The Monte Carlo analysis confirms that the variation of PHs concentration significantly correlates with the river input. The water body in the bay is reasonably subjected to self-purification processes, such as volatilization to the atmosphere, biodegradation by microorganism, and transport to the Yellow Sea by water exchange. The environmental capacity of PHs in Jiaozhou Bay is 1500 tons per year IF the seawater quality criterion (Grade Ⅰ/Ⅱ, 0.05 mgL-1) in the region is to be satisfied. The contribution to self-purification by volatilization, biodegradation, and transport to the Yellow Sea accounts for 48%, 28%, and 23%, respectively, which make these three processes the main ways of PHs purification in Jiaozhou Bay. | LI Keqiang SU Ying YING Jun WANG Xiulin MU Jinbo | 2013 | Journal of Ocean University of China2013，12，1： | 3 |
| 11 | Characterization of chromophoric dissolved organic matter(CDOM) in the East China Sea in autumn using excitationemission matrix(EEM) fluorescence and parallel factor analysis(PARAFAC)显示文摘Samples of chromophoric dissolved organic matter(CDOM)in the East China Sea in autumn(October in 2011)were analyzed by excitation emission matrix(EEM)fluorescence spectroscopy combined with parallel factor analysis(PARAFAC).Three terrestrial humic-like components(C1,C2 and C3)and one protein-like component(C4)were identified.Based on spatial distributions,as well as relationships with salinity,the following assignments were made.The three humic-like components(C1,C2 and C3)showed conservative mixing behavior and came mainly from riverine input.The protein-like component(C4)was considered a combination of autochthonous production and terrestrial inputs and a biologically labile component.Path analysis of samples from the middle and bottom layers revealed that the causal effects on C1 were 78.46%for salinity,and 21.54%for apparent oxygen utilization(AOU);those on C2 were 76.43%for salinity,and 23.57%for AOU;those on C3 were70.49%for salinity,7.01%for Chl-a,and 22.50%for AOU;those on C4 were 55.54%for salinity,14.6%for Chl-a,and29.86%for AOU in middle layer;and those on C4 were 57.37%for salinity,29.02%for Chl-a,and 13.61%for AOU in bottom layer.Results indicated that CDOM in the East China Sea was mainly affected by terrestrial inputs,and microbial activities also played a key role in biogeochemical processes of CDOM.The application of the EEM-PARAFAC model presented a unique opportunity to observe compositional changes in CDOM in the East China Sea.In addition,the humification index(HIX)suggested that CDOM from the East China Sea was less stable and stayed shorter in the environment. | BAI Ying SU RongGuo YAN LiHong YAO Peng SHI XiaoYong WANG XiuLin | 2013 | Science China Chemistry2013，56，12： | 3 |
| 12 | Modelling Nitrogen and Phosphorus Dynamics in a Mesocosm Pelagic Ecosystem in Laizhou Bay in China显示文摘A model of nitrogen and phosphorus dynamics in mesocosm experiments was established on the basis of a summary and synthesis of the existing models. The established model comprised seven state variables(DIN,PO4-P,DON,DOP,phytoplankton,zooplankton and detritus) and five modules - phytoplankton,zooplankton,dissolved inorganic nutrients,dissolved organic nutrients and detritus. Comparison with the in situ experimental data in Laizhou Bay at the end of August 2002 showed that this model could properly simulate the variations of DIN,PO4-P,and phytoplankton biomass in a mesocosm pelagic ecosystem. It was found that not only the model structure but also the parameters adopted were fit for simulation. The sensitivity of the main state variables to the parameter change was assessed by sensitivity analysis. All these results are useful for studying the control mechanism of biogeochemical cycling of nutrients in Laizhou Bay and other Chinese coastal waters. | LI Keqiang WANG Xiulin HAN Xiurong SHI Xiaoyong CHEN Hu | 2009 | Journal of Ocean University of China2009，8，2： | 3 |
| 13 | Electron-transfer enhanced MoO2-Ni heterostructures as a highly efficient pH-universal catalyst for hydrogen evolution显示文摘Hydrogen is one of the most promising energy carriers to replace fossil fuels and electrolyzing water to produce hydrogen is a very effective method.However,designing highly active and stable non-precious metal hydrogen evolution electrocatalysts that can be used in universal pH is a huge challenge.Here,we have reported a simple strategy to develop a highly active and durable non-precious MoO2-Ni electrocatalyst for hydrogen evolution reaction(HER)in a wide pH range.The MoO2-Ni catalyst exhibits a superior electrocatalytic performance with low overpotentials of 46,69,and 84 mV to reach-10 mA cm-2 in 1.0 M KOH,0.5 M H2SO4,and 1.0 M PBS electrolytes,respectively.At the same time,the catalyst also shows outstanding stability over a wide pH range.It is particularly noted that the catalytic performance of MoO2-Ni in alkaline solution is comparable to the highest performing catalysts reported.The outstanding HER performance is mainly attributed to the collective effect of the rational morphological design,electronic structure engineering,and strong interfacial coupling between MoO2 and Ni in heterojunctions.This work provides a viable method for the synthesis of inexpensive and efficient HER electrocatalysts for the use in wide pH ranges. | Benzhi Wang Hexiu Huang Meilin Huang Puxuan Yan Tayirjan Taylor Isimjan Xiulin Yang | 2020 | Science China Chemistry2020，63，6： | 3 |
| 14 | Temporal and spatial distribution of dissolved copper,lead,zinc and cadmium in the Changjiang Estuary and its adjacent waters显示文摘Heavy metal concentrations were measured in the Changjiang Estuary and its adjacent waters.Results from a systematic survey in April 2002 to March 2003 indicate that the ranges of the concentrations of dissolved copper,lead,zinc and cadmium in the study waters are 1.01~6.86,0.10~0.39,3.17~9.12 and 0.011~0.049 μg/dm3,respectively.Similar to zinc,the behavior of dissolved copper was essentially conservative,but high scatter has been observed for high salinity samples,which can be attributed to the decomposition or mineralization of organic matter by bacteria.Dissolved lead may have active behavior with an addition at high salinity.Overall concentrations of dissolved cadmium increase with salinity.The mean values of these dissolved metals calculated for the surface waters were higher than those for the middle and bottom ones.External inputs of dissolved heavy metals to the surface waters were the likely explanation for these higher values.The maximum seasonal average values of dissolved copper and zinc were found in summer,reflecting higher amounts of riverine input in this season.In contrast,the maximum seasonal average values of dissolved lead and copper were found in winter and the lowest ones in summer,respectively,which might be associated with a combination of low concentration with heterogeneous scavenging.Concentrations of these dissolved metals found for the Changjiang Estuary fall in the range observed for the other estuaries but are noticeably higher than those from uncontaminated rivers,except for cadmium.Compared with observations for the Changjiang Estuary in the last two decades,it is clear that the Changjiang estuarine waters has been contaminated with copper,lead,zinc and cadmium during China's industrialization,but concentrations of them have decreased in the last few years. | WANG Changyou WANG Xiulin WANG Baodong ZHANG Chuansong SHI Xiaoyong ZHU Chenjian | 2008 | Acta Oceanologica Sinica2008，27，4： | 2 |

| 17 | Three-Dimensional Water Quality Model Based on FVCOM for Total Load Control Management in Guan River Estuary,Northern Jiangsu Province显示文摘Guan River Estuary and adjacent coastal area(GREC) suffer from serious pollution and eutrophicational problems over the recent years.Thus,reducing the land-based load through the national pollutant total load control program and developing hydrodynamic and water quality models that can simulate the complex circulation and water quality kinetics within the system,including longitudinal and lateral variations in nutrient and COD concentrations,is a matter of urgency.In this study,a three-dimensional,hydrodynamic,water quality model was developed in GREC,Northern Jiangsu Province.The complex three-dimensional hydrodynamics of GREC were modeled using the unstructured-grid,finite-volume,free-surface,primitive equation coastal ocean circulation model(FVCOM).The water quality model was adapted from the mesocosm nutrients dynamic model in the south Yellow Sea and considers eight compartments:dissolved inorganic nitrogen,soluble reactive phosphorus(SRP),phytoplankton,zooplankton,detritus,dissolved organic nitrogen(DON),dissolved organic phosphorus(DOP),and chemical oxygen demand.The hydrodynamic and water quality models were calibrated and confirmed for 2012 and 2013.A comparison of the model simulations with extensive dataset shows that the models accurately simulate the longitudinal distribution of the hydrodynamics and water quality.The model can be used for total load control management to improve water quality in this area. | ZHANG Li LIN Weibo LI Keqiang SHENG Jianming WEI Aihong LUO Feng WANG Yan WANG Xiulin ZHANG Longjun | 2016 | Journal of Ocean University of China2016，15，2： | 1 |
