1Economic feasibility of large-scale hydro–solar hybrid power including long distance transmission显示文摘Solar PV is expected to become the most cost-competitive renewable energy owing to the rapidly decreasing cost of the system. On the other hand, hydropower is a high-quality and reliable regulating power source that can be bundled with solar PV to improve the economic feasibility of long-distance transmitted power. In this paper, a quantification model is established taking into account the regulating capacity of the reservoir, the characteristics of solar generation, and cost of hydro and solar PV with long-distance transmission based on the installed capacity ratio of hydro–solar hybrid power. Results indicate that for hydropower stations with high regulating capacity and generation factor of approximately 0.5, a hydro–solar installed capacity ratio of 1:1 will yield overall optimal economic performance, whereas for hydropower stations with daily regulating capacity reservoir and capacity factor of approximately 0.65, the optimal hydro–solar installed capacity ratio is approximately 1:0.3. In addition, the accuracy of the approach used in this study is verified through operation simulation of a hydro–solar hybrid system including ultra high-voltage direct current(UHVDC) transmission using two case studies in Africa.Zhenchen Deng Jinyu Xiao Shikun Zhang Yuetao Xie Yue Rong Yuanbing Zhou 2019Global Energy Interconnection2019,2,4:6
2Optimal design on the high-temperature mechanical properties of porous alumina ceramics based on fractal dimension analysis显示文摘Fractal theory and regression analysis were employed for the first time to investigate the effect of pore size and pore distribution on high-temperature mechanical properties of porous alumina ceramics(PAC). In the present work, PAC with the comparable porosity, different pore sizes and pore distributions were prepared using carbon black as the pore-forming agent. Particular emphasis in this study was placed on the establishment of correlation between the thermal shock resistance and pore properties. The relationship between fractal dimension(D_f) and thermal shock resistance parameter(R_(st)) in specimens presented the negative power function, indicating that low D_f could benefit the improvement of thermal shock resistance in specimens. The results showed that the increase of pore size and pore sphericity leads to a reduced D_f, the enhanced hot modulus of rupture(HMOR) and R_(st). The decrease of proportion of micro-pores below 2 μm, the increase of mean pore size and pore sphericity could result in the decrease of D_f, and then improve R_(st) and HMOR of specimens. Based on the correlation between R_(st) and pore characteristics, PAC with improved thermal shock resistance could be achieved when their pore structure meets the above features.Jingjing LIU Wenlong HUO Xiaoyan ZHANG Bo REN Yuanbing Li Zaijuan ZHANG Jinlong YANG 2018Journal of Advanced Ceramics2018,7,2:4
3The atlas of cytoophidia in Drosophila larvae显示文摘In 2010,cytidine 50-triphosphate synthase(CTPS)was reported to form the filamentous or serpentine structure in Drosophila,which we termed the cytoophidium.In the last decade,CTPS filaments/cytoophidia have been found in bacteria,budding yeast,human cells,mice,fission yeast,plants,and archaea,indicating that this mechanism is highly conserved in evolution.In addition to CTPS,other metabolic enzymes have been identified to have the characteristics of forming cytoophidia or similar advanced structures,demonstrating that this is a basic strategy of cells.Nevertheless,our understanding of the physiological function of the cytoophidium remains incomplete and elusive.Here,we took the larva of Drosophila melanogaster as a model to systematically describe the localization and distribution of cytoophidia in different tissues during larval development.We found that the distribution pattern of CTPS cytoophidia is dynamic and heterogenic in larval tissues.Our study provides a road map for further understanding of the function and regulatory mechanism of cytoophidia.Yuanbing Zhang Jingnan Liu Ji-Long Liu 2020Journal of Genetics and Genomics2020,47,6:2
4Development of RSDS-III Technology for Ultra-Low-Sulfur Gasoline Production显示文摘The 3rd generation catalytic cracking naphtha selective hydrodesulfurization(RSDS-III) technology developed by RIPP included the catalysts selective adjusting(RSAT) technology, the development of new catalysts and optimized process conditions. The pilot plant test results showed that the RSDS-III technology could be adapted to different feedstocks. The sulfur content dropped from 600 μg/g and 631 μg/g to 7 μg/g and 9 μg/g, respectively, by RSDS-III technology when feed A and feed B were processed to meet China national V gasoline standard, with the RON loss of products equating to 0.9 units and 1.0 unit, respectively. While the feed C with a medium sulfur content was processed according to the full-range naphtha hydrotreating technology, the sulfur content dropped from 357 μg/g in the feed to 10 μg/g in gasoline, with the RON loss of product decreased by only 0.6 units. Thanks to the high HDS activity and good selectivity of RSDS-III technology, the ultra-low-sulfur gasoline meeting China V standard could be produced by the RSDS-III technology with little RON loss.Xi Yuanbing Zhang Dengqian Chu Yang Gao Xiaodong 2015China Petroleum Processing & Petrochemical Technology2015,17,2:2
5Kinetic Model of LCO Selective Hydrogenation on NiMoW/Al_(2)O_(3) Catalyst显示文摘In order to investigate the hydrofining process of LCO for producing aromatics and gasoline,the selective hydrogenation of polycyclic aromatic hydrocarbons(PAHs),a major component of light cycle oil(LCO),was studied using a NiMoW/Al_(2)O_(3)catalyst.Based on the study of the reversible hydrogenation reaction,PAHs in the selective hydrogenation process could be effectively simulated by the modeled CH and CH_(2) groups,and the hydrodesulfurization and hydrodenitrogenation kinetic models could be further established in this process.The results showed that the kinetic models developed could fit the experimental data effectively and predict the content of S,N,and aromatics in the selective hydrogenation products of LCO.Ju Xueyan Zhang Kui Xi Yuanbing Wang Zhe Nie Hong 2022China Petroleum Processing & Petrochemical Technology2022,24,3:2

7Process Optimization of RTS Technology for Ultra-Low Sulfur Diesel显示文摘The RTS technology can produce ultra-low sulfur diesel at lower costs using available hydrogenation catalyst and device.However,with the increase of the mixing proportion of secondary processed diesel fuel in the feed,the content of nitrogen compounds and polycyclic aromatic hydrocarbons in the feed increased,leading to the acceleration of the deactivation rate of the primary catalyst and the shortening of the service cycle.In order to fully understand the reason of catalyst deactivation,the effect of mixing secondary processed diesel fuel oil on the operating stability of the catalyst in the first reactor was investigated in a medium-sized fixed-bed hydrogenation unit.The results showed that the nitrogen compounds mainly affected the initial activity of the catalyst,but had little effect on the stability of the catalyst.The PAHs had little effect on the initial activity of the catalyst,but could significantly accelerate the deactivation of the catalyst.Combined with the analysis of the reason of catalyst deactivation and the study of RTS technology,the direction of RTS technology process optimization was put forward,and the stability of catalyst was improved obviously after process optimization.Ge Panzhu Ding Shi Xi Yuanbing Zhang Le Nie Hong Li Dadong 2021China Petroleum Processing & Petrochemical Technology2021,23,3:1
8Effect of Polycyclic Aromatic Hydrocarbons on the Stability of Hydrogenation Catalyst for Producing Ultra-Low Sulfur Diesel显示文摘The effect of polycyclic aromatic hydrocarbons(PAHs)on the stability of the hydrogenation catalyst for production of ultra-low sulfur diesel was studied in a pilot plant using Ni-Mo-W/γ-Al_(2)O_(3)catalyst.The mechanisms of catalyst deactivation were analyzed by the methods of elemental analysis,nitrogen adsorption-desorption,thermogravimetry-mass spectrometry(TG-MS)technology,X-ray photoelectron spectroscopy(XPS)and high resolution transmission electron microscopy(HRTEM).The results demonstrated that PAHs had little effect on the activity of catalyst at the beginning of operation,during which the reaction temperature was increased by only 1-4℃.However,the existence of PAHs significantly accelerated the deactivation of catalyst and weakened the stability of catalyst.This phenomenon could be explained by the reason that the catalyst deactivation is not only related to the formation of carbon deposit,but is also closely related to the loss of pore volume and the decrease of Ni-W-S phase ratio after adding PAHs.Ding Shi Ge Panzhu Zhang Rui Xi Yuanbing Zhang Le Li Dadong Nie Hong 2022China Petroleum Processing & Petrochemical Technology2022,24,1:0
9Adjustable robust low-carbon dispatch for interconnected power systems in Northeast Asian countries显示文摘Interconnected power systems that link several countries and fully utilize their individual resources in a complementary manner are becoming increasingly important.As these systems enhanee accommodation of renewable energy,they also represent a move toward low-carbon and low-emissi on power systems.In this paper,a low-carb on dispatch model is proposed to coo rd i nate the gen erati on output betwee n several coun tries where the carb on emissi on constraint is a priority.An adjustable robust optimization approach is used to find the optimal solution under the worst-case scenario to address the uncertainties associated with renewable energy resources.A specific constraint is that the area control error for each country should be self-balanced.Furthermore,a reformation using participation factors is presented to simplify the proposed robust dispatch model.Simulation results for practical interconnected power systems in northeast Asian countries verify the effectiveness of the proposed model.Ming Qu Tao Ding Qingrun Yang Yuanbing Zhou Yun Zhang Ya Wen 2020Global Energy Interconnection2020,3,6:0
10Effects of Different Carbon Sources and NaBr-KCl on Synthesis of Ti(C,N)显示文摘Ti(C,N)was synthesized with the starting materials of 76.9% titania white and 23.1% carbon black(graphite or activated carbon),or 40% titania white and 60% amylum,with or without 10% NaBr-KCl,dry moulding and carbon embedded firing at 1 300 ℃ and 1 400 ℃ for 3 h,respectively.Phase composition and microstructure of the synthesized Ti(C,N)were analyzed by XRD,SEM and EPMA.Effects of different carbon sources and NaBr-KCl on the synthesis of Ti(C,N)were investigated.The results show that:(1)Ti(C,N)can be synthesized by using carbon black,graphite,activated carbon or amylum as carbon source separately;(2)Additive NaBr-KCl is more favorable for accelerating the carbothermal reduction reaction using carbon black or amylum as carbon source;(3)In the presence of NaBr-KCl,particle size of the synthesized Ti(C,N)is 5-8 μm using carbon black as carbon source fired at 1 300 ℃ for 3 h,while that is only 1-3 μm using graphite,activated carbon or amylum fired at 1 400 ℃ for 3 h.CHEN Xilai LI Yuanbing ZHANG Renhua LI Yawei LI Jun 2008China's Refractories2008,17,4:0
