| 1 | Development of Light Cycle Oil(LCO) Hydrocracking Technology over a Commercial W-Ni Based Catalyst显示文摘Because of its high density and low cetane number, the light cycle oil(LCO) containing heavy aromatics(60%—80%) can hardly be transformed through the conventional hydro-upgrading technology. In this report, a novel LCO hydrocracking technology(FD2G) was proposed for the utilization of LCO to manufacture high value-added products. Through the ingenious combination of hydroprocessing catalyst and the hydrocracking process, the high octane gasoline and the ultra-low sulfur diesel(ULSD) blendstocks were produced simultaneously. The influence of catalyst type, reaction temperature, pressure, respectively, on the research octane number(RON) of produced gasoline was studied in a fixed bed hydrogenation reactor. It indicated that high reaction temperature and medium pressure would favor the production of highoctane gasoline through the conversion of bi-aromatic and tri-aromatic hydrocarbons. The typical results of FD2 G technology on commercial units showed that it could produce clean diesel with a sulfur content of less than 10 μg/g and clean gasoline with a research octane number(RON) of up to 92. It would be contributed to the achievement of the maximum profit of a refinery, the FD2 G technology could provide a higher economic efficiency than the other diesel quality upgrading technology under the current gasoline and diesel price system. | Peng Chong Yang Xuejing Fang Xiangchen Huang Xinlu Cheng Zhenmin Zeng Ronghui Guo Rong | 2015 | China Petroleum Processing & Petrochemical Technology2015，17，4： | 9 |
| 2 | Regulating catalyst morphology to boost the stability of Ni–Mo/Al_(2)O_(3) catalyst for ebullated-bed residue hydrotreating显示文摘Hydrotreating of vacuum residue by ebullated-bed shows tremendous significance due to more stringent environmental regulations and growing demand for lighter fuels. However, enhancing the catalyst stability still remains as a challenging task. Herein, two Ni–Mo/Al_(2)O_(3) catalysts with distinct morphologies(i.e., spherical and cylindrical) were first designed, and the morphology effect on deactivation was systematically elucidated employing multi-characterizations, such as HRTEM with EDX mapping, electron microprobe analysis, FT-IR, TGA and Raman. It is found that spherical catalyst exhibits superior hydrotreating stability over 1600 h. The carbonaceous deposits on spherical catalyst with less graphite structure are lighter, and the coke weight is also smaller. In addition, the metal deposits uniformly distribute in the spherical catalyst, which is better than the concentrated distribution near the pore mouth for the cylindrical catalyst. Furthermore, the intrinsic reason for the differences was analyzed by the bed expansion experiment. Higher bed expansion rate together with the better mass transfer ability leads to the enhanced performance. This work sheds new light on the design of more efficient industrial hydrotreating catalyst based on morphology effect. | Huihong Zhu Zhiwei Mao Bin Liu Tao Yang Xiang Feng Hao Jin Chong Peng Chaohe Yang Jifeng Wang Xiangchen Fang | 2021 | Green Energy & Environment2021，6，2： | 4 |

| 4 | Experimental Study of Integrated Ebullated-bed and Fixed-bed for Hydrotreating Mid-Low Temperature Coal Tar to Clean Fuel显示文摘A new hydrotreating technology integrating the ebullated-bed(EB) and the fixed-bed(FB) hydrogenation was proposed to investigate the efficiency for hydrotreating mid- low-temperature coal tar to clean fuel, and multiple tests at the bench scale were carried out. The results showed that the distillates obtained from EB reactors were greatly upgraded and could meet the requirements of FB unit without discarding any tail oil. The naphtha produced from FB reactors could be fed to the catalytic reforming unit, while a high quality diesel was also obtained. The unconverted oil(UCO) could be further hydrocracked to clean fuel. It is found that the removal of impurities from the coal tar oil is related with the molecular aggregation structure and composition of the coal tar. Application of the integrated hydrotreating technology to the hightemperature coal tar processing demonstrated that more than half of heavy components could be effectively upgraded. | Meng Zhaohui Yang Tao Fang Xiangchen | 2016 | China Petroleum Processing & Petrochemical Technology2016，18，3： | 2 |

| 9 | High-performance Ta-doped Li_(7)La_(3)Zr_(2)O_(12) garnet oxides with AlN additive显示文摘Garnet-type oxide is one of the most promising solid-state electrolytes(SSEs)for solid-state lithium-metal batteries(SSLMBs).However,the Li dendrite formation in garnet oxides obstructs the further development of the SSLMBs seriously.Here,we report a high-performance garnet oxide by using AlN as a sintering additive and Li as an anode interface layer.AlN with high thermal conductivity can promote the sintering activity of the garnet oxides,resulting in larger particle size and higher relative density.Moreover,Li3N with high ionic conductivity formed at grain boundaries and interface can also improve Li-ion transport kinetics.As a result,the garnet oxide electrolytes with AlN show enhanced thermal conductivity,improved ionic conductivity,reduced electronic conductivity,and increased critical current density(CCD),compared with the counterpart using Al_(2)O_(3) sintering aid.In addition,Li symmetric cells and Li|LiFePO_(4)(Li|LFP)half cells using the garnet electrolyte with the AlN additive exhibit good electrochemical performances.This work provides a simple and effective strategy for high-performance SSEs. | Chang ZHANG Xiangchen HU Zhiwei NIE Cong WU Nan ZHENG Shaojie CHEN Yihang YANG Ran WEI Jiameng YU Nan YANG Yi YU Wei LIU | 2022 | Journal of Advanced Ceramics2022，11，10： | 1 |

| 12 | 2-4 First Isochronous Mass Measurement in Neutron-rich Region at CSRe显示文摘Mass is one of the fundamental properties of atomic nuclei. Isochronous mass spectrometry (IMS), using astorage ring combined with an in-flight separator, has been shown to be a powerful tool for mass measurementof exotic nuclei[1]. Recently, masses of many proton-rich nuclides were accurately determined at the HIRFL-CSRfacility[2]. In this paper, we described the first isochronous mass measurement of neutron-rich nuclides at CSRe.This experiment was performed at the end of 2011. In the experiment, the primary beam of 86Kr28+ ions wasaccumulated and accelerated to an energy of 460.65 MeV/u in the synchrotron CSRm. The 86Kr28+ ions were fastextracted and focused on a 15 mm thick beryllium target which was placed at the entrance of the RIBLL2 (anin-flight fragment separator). | Xu Xing Wang Meng Zhang Yuhu Xu Hushan Tu Xiaolin Yu.A.Litvinov Zhou Xiaohong Sun Baohua Yuan Youjin Xia Jiawen Yang Jiancheng K.Blaum Chen Ruijiu Chen Xiangchen Fu Chaoyi Ge Zhuang Hu Zhengguo Huang Wenjia Liu Dawei Y.H.Lam Ma Xinwen Mao Ruishi T.Uesaka Xiao Guoqing Xing Yuanming T.Yamaguchi Y.Yamaguchi Zeng Qi Yan Xinliang Zhao Hongwei Zhao Tiecheng Zhang Wei Zhan Wenlong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 13 | Ambipolar two-dimensional bismuth nanostructures in junction with bismuth oxychloride显示文摘Despite the unique properties of bismuth(Bi),there is a lack of two-dimensional(2D)heterostructures between Bi and other functional 2D materials.Here,a coherent strategy is reported to simultaneously synthesize rhombohedral phase Bi nanoflakes and bismuth oxychloride(BiOCI)nanosheets.The delicate balance between several reactions is mediated mainly for the reduction and chlorination in the chemical vapor transport(CVT)process.The Bi-BiOCI lateral heterostructures have been constructed via the coalescence of the two different 2D nanostructures.The characteristics of ambipolar conducting Bi and insulator-like BiOCI are elaborated by scanning microwave impedance microscopy(sMIM).This work demonstrates a way to construct a 2D Bi nanostructure in junction with its oxyhalide. | Xianzhong Yang Shengnan Lu Jun Peng Xiangchen Hu Nan Wu Congcong Wu Chao Zhang Yifan Huang Yi Yu Hung-Ta Wang | 2021 | Nano Research2021，14，4： | 0 |

| 15 | Grain boundary boosting the thermal stability of Pt/CeO_(2)thin films显示文摘Understanding how defect chemistry of oxide material influences the thermal stability of noble metal dopant ions plays an important role in designing high-performance heterogeneous catalytic systems.Here we use in-situ ambient-pressure X-ray photoemission spectroscopy(APXPS)to experimentally determine the role of grain boundary in the thermal stability of platinum doped cerium oxide(Pt/CeO_(2)).The grain boundaries were introduced in Pt/CeO_(2)thin films by pulsed laser deposition without significantly change of the surface microstructure.The defect level was tuned by the strain field obtained using a highly/low mismatched substrate.The Pt/CeO_(2)thin film models having well defined crystallographic properties but different grain boundary structural defect levels provide an ideal platform for exploring the evolution of Pt–O–Ce bond with changing the temperature in reducing conditions.We have direct demonstration and explanation of the role of Ce^(3+)induced by grain boundaries in enhancing Pt2+stability.We observe that the Pt^(2+)–O–Ce^(3+)bond provides an ideal coordinated site for anchoring of Pt^(2+)ions and limits the further formation of oxygen vacancies during the reduction with H_(2).Our findings demonstrate the importance of grain boundary in the atomic-scale design of thermally stable catalytic active sites. | Luyao Wang Xiaobao Li Xiangchen Hu Shuyue Chen Zhehao Qiu Yifan Wang Hui Zhang Yi Yu Bo Yang Yong Yang Pasquale Orgiani Carmela Aruta Nan Yang | 2023 | Nano Research2023，16，2： | 0 |
