| 3 | Research on Optimized Utilization of Naphtha Resources Based on Adsorptive Separation with Zeolite显示文摘By means of molecular scale management, the technology of separating normal paraffins from naphtha through adsorption using 5A molecular sieves was studied with the purpose of optimizing the utilization of naphtha. The raw materials used in steam cracking and catalytic reforming processes could be allocated properly. During the adsorption process, the separation efficiency of the normal paraffins was above 99.9% with the purity of normal paraffins in the desorption oil exceeding 98.2%. With the use of the desorption oil as the feedstock of steam cracking, the ethylene yield increased from 29.7%-35.0% to 41.4%- 49.2% compared to that of the naphtha in the existing plant under similar operation conditions. The potential aromatic content of the raffinate oil rose from 30.6% to 43.5% compared to that in naphtha. The research octane number of the raffinate oil reached more than 85 with an increase of 20 units compared to that of naphtha, so the raffinate oil is more suitable for use as a blending component for high-octane clean gasoline. | Shen Benxian Liu Jichang, Wang Zhenxian (Petroleum Processing Research Center, East China University of Science and Technology, Shanghai 200237) | 2005 | China Petroleum Processing & Petrochemical Technology2005,7,1: | 8 |
| 4 | Simultaneous Removal of H_2S and Organosulfur Compounds from Liquefied Petroleum Gas Using Formulated Solvents: Solubility Parameter Investigation and Industrial Test显示文摘The performance of four formulated solvents(labeled as UDS-I, UDS-II, UDS-III, and UDS-IV) for removing methyl mercaptan from liquefied petroleum gas was predicted based on a two-dimensional solubility parameter theory. The calculation results show that UDS-IV has the closest solubility parameter to that of methyl mercaptan as compared with other tested solvents, indicating the strongest affinity and the highest solubility for methyl mercaptan. The industrial tests at a plant for desulfurization of LPG produced from the delayed coker have shown that the UDS solvents have the excellent performance for removal of organosulfur compounds(mainly methyl mercaptan). Although the sulfur loading dramatically increases, the total sulfur content of LPG treated with UDS-IV can be reduced by about 50% in comparison with N-methyl diethanolamine. In addition, UDS-IV has superior regeneration performance and selectivity for sulfur compounds over hydrocarbons. The industrial test and the solubility parameter calculation results are in good agreement with each other. | Zhang Feng Shen Benxian Sun Hui Liu Jichang Shang Jianfeng | 2015 | China Petroleum Processing & Petrochemical Technology2015,17,1: | 6 |
| 5 | Rheological properties and viscosity reduction of South China Sea crude oil显示文摘The rheological properties of South China Sea(SCS) crude oil were studied. A group of synthetic long-chain polymers, including octadecyl acrylate-maleic anhydride bidodecyl amide copolymer(VR-D),octadecyl acrylate-maleic anhydride bioctadecyl amide copolymer(VR-O) and octadecyl acrylate-maleic anhydride phenly amide copolymer(VR-A), were employed to serve as viscosity reducers(VRs). Their performance was evaluated by both experimental and computational methodologies. The results suggest that the SCS crude oil has low wax content yet high resin and asphaltene contents, which lead to high viscosity through formation of association structures. Additionally, the SCS crude oil appears to be a pseudoplastic fluid showing linear shear stress-shear rate dependence at low temperature. Interestingly, it gradually evolves into a Newtonian fluid with exponential relationship between shear stress and shear rate at higher temperature. Synthetic VRs demonstrate desirable and effective performance on improvement of the rheological properties of SCS crude oil. Upon the introduction of 1000 ppm VR-O,which is synthesized by using octadecylamine in the aminolysis reaction, the viscosity of SCS crude oil is decreased by 44.2% at 15 °C and 40.2% at 40 °C. The computational study suggests significant energy level increase and shear stress decrease for VR-containing crude oil systems. | Hui Sun Xingxing Lei Benxian Shen Huiran Zhang Jichang Liu Gengnan Li Di Wu | 2018 | Journal of Energy Chemistry2018,27,4: | 5 |
| 6 | Baicalin inhibits colistin sulfate-induced apoptosis of PC12 cells显示文摘Baicalin,a type of flavonoid extracted from the dried root of Scutellaria baicalensis georgi,has been shown to effectively inhibit cell apoptosis.Therefore,we assumed that baicalin would suppress colistin sulfate-induced neuronal apoptosis.PC12 cells exposed to colistin sulfate(62.5–500μg/mL)for 24 hours resulted in PC12 cell apoptosis.In addition,caspase-3 activity,lactate dehydrogenase level and free radical content increased in a dose-dependent manner.Subsequently,PC12 cells were pretreated with baicalin(25,50 and 100μg/mL),and exposed to 125μg/mL colistin sulfate.Cell morphology markedly changed,and cell viability increased.Moreover,caspase-3 activity,lactate dehydrogenase level and free radical content decreased.Results indicated that baicalin inhibited colistin sulfate-induced PC12 cell apoptosis by suppressing free radical injury,and reducing caspase-3 activity and lactate dehydrogenase activity. | Hong Jiang Pengfei Lv Jichang Li Hongjun Wang Tiezhong Zhou Yingzi Liu Wei Lin | 2013 | Neural Regeneration Research2013,8,28: | 4 |
| 7 | Recent progress in Mg-based alloys as a novel bioabsorbable biomaterials for orthopedic applications显示文摘Traditional orthopedic metal implants,such as titanium(Ti),Ti alloys,and cobalt-chromium(Co-Cr)alloys,cannot be degraded in vivo.Fracture patients is must always suffer a second operation to remove the implants.Moreover,stress shielding,or stress protection occurs when traditional orthopedic metal implants are applied in fractures surgery.The mechanical shunt produced by traditional orthopedic metal implants can cause bone loss over time,resulting in decreased bone strength and delayed fracture healing.Biodegradable metals that‘biocorrode’are currently attracting significant interest in the orthopedics field due to their suitability as temporary implants.As one of the biodegradable metals,magnesium(Mg)and Mg alloys have gained interest in the field of medicine due to their low density,excellent biocompatibility,high bioresorbability,and proper mechanical properties.Additionally,Mg ions released from the metal implants can promote osteogenesis and angiogenesis during the degradation process in vivo,which is substantially better for orthopedic fixation than other bioinert metal materials.Therefore,this review focuses on the properties,fabrication,biological functions,and surface modification of Mg-based alloys as novel bioabsorbable biomaterials for orthopedic applications. | Fei Xing Shang Li Dongdi Yin Jichang Xie Pol Maria Rommens Zhou Xiang Ming Liu Ulrike Ritz | 2022 | Journal of Magnesium and Alloys2022,10,6: | 3 |
| 8 | Comparison on Adsorptive Separation of n-Paraffins Based on Binderless and Binder-containing Zeolite 5A Pellets显示文摘Binderless zeolite is considered to be a potential alternative for binder-containing zeolite in the industrial applications of adsorptive separation process. Synthesized binderless zeolite and commercial binder-containing product were used in adsorptive separation of n-paraffins from a model oil, with their performance compared. It is indicated that the binderless zeolite exhibits by 25%-35% higher in saturated adsorption capacity and by 115%-130% more adsorption amount at the breakthrough point with much shorter length of mass-transfer zone. Adsorptive separation of n-paraffins from naphtha was carried out in a fixed-bed adsorber containing the synthesized binderless zeolite 5 A under the operating conditions covering a feed space velocity of 90 h-1 and an adsorption temperature of 573 K. As compared to original naphtha, the raffinate shows by 34 units more in research octane number and by around 10% more of potential aromatic content, while the desorption oil exhibits by 13.3% more ethylene yield and by 11.7% higher in total olefins yield. | Kong Ruiqi Jiang Hao Wang Dan Tan Jialun Ren Danni Sun Hui Shen Benxian Liu Jichang Tang Sheng Zhao Deyin Chang Xiaohu | 2019 | China Petroleum Processing & Petrochemical Technology2019,21,4: | 2 |
| 9 | The Productive Service Industry and Modern Economic Growth显示文摘Productive services refers to market-ized non-ultimate consumption services, i.e., services as intermediate inputs of other products or service production, taking place continuously in various stages of production. The productive service industry is knowledge- and technology-intensive and changes the contents and nature of service products and their position and role in the national economy. Serving as an economic 'bonding agent,' the productive service industry becomes a driver of modern economic growth and boosts economic competitiveness. Services are increasingly entering the productive field as a soft means of production and play an important role in raising economic efficiency and competitiveness. | Zheng Jichang, Professor, Zhejiang Shuren University Liu Qingyun | 2006 | Social Sciences in China2006,27,1: | 2 |
