| 1 | Study on Al2O3 Extraction From Activated Coal Gangue under Different Calcination Atmospheres显示文摘Coal gangue was calcinated under air, nitrogen, carbon dioxide, air-hydrogen, and hydrogen atmospheres. The effects of different calcination temperatures and atmospheres on the mineral composition of activated coal gangue were investigated by X-ray diffraction. Moreover, the acid leaching kinetics of aluminum oxide from coal gangue was investigated with sulfuric acid. It showed that the air atmosphere promoted kaolinite decomposition during coal gangue calcination. The hydrogen atmosphere promoted the activation and decomposition of kaolinite at reaction temperatures exceeding 650℃. The carbon dioxide atmosphere eliminated the influence of residual carbon on coal gangue. When the ratio of acid/coal gangue was 1.5 and reaction temperature was 650℃, the sulfuric acid leaching rate under air,air-hydrogen,carbon dioxide,hydrogen and nitrogen atmospheres were 93.66%,90.90%, 84.06%, 81.91% and 77.54% respectively. The acid leaching reaction process conformed to unreacted shrinking core model of particle unchanged, and was controlled by the interfacial chemical reaction. The reaction kinetic equation for the leaching process was 1-(1-x)1/3=kt with an apparent activation energy of 48.97 kJ/mol. | DONG Ling LIANG Xinxing SONG Qiang GAO Gewu SONG Lihua SHU Yuanfeng SHU Xinqian | 2017 | Journal of Thermal Science2017，26，6： | 7 |
| 2 | Non‑Leaching,Rapid Bactericidal and Biocompatible Polyester Fabrics Finished with Benzophenone Terminated N‑halamine显示文摘Pathogenic bacteria can proliferate rapidly on porous fabrics to form bacterial plaques/bioflms,resulting in potential sources of cross-transmissions of diseases and increasing cross-infection in public environments.Many works on antibacterial modifcation of cotton fabrics have been reported,while very few works were reported to endow poly(ethylene terephthalate)(PET)fabrics with non-leaching antibacterial function without compromising their innate physicochemical properties though PET is the most widely used fabric.Therefore,it is urgent to impart the PET fabrics with non-leaching antibacterial activity.Herein,a novel N-halamine compound,1-chloro-3-benzophenone-5,5-dimethylhydantoin(Cl-BPDMH),was developed to be covalently bonded onto PET fabrics,rendering non-leaching antibacterial activity while negligible cytotoxicity based on contact-killing principle.Bacterial was easily adhered to Cl-BPDMH fnished PET fabrics,and then it was inactivated quickly within 10 s.Furthermore,the breaking strength,breaking elongation,tearing strength,water vapor permeability,air permeability and whiteness of Cl-BPDMH fnished PET fabrics were improved obviously compared to raw PET fabrics.Hence,this work developed a facile approach to fabricate multifunctional synthetic textiles to render outstanding and rapid bactericidal activity without compromising their physicochemical properties and biocompatibility. | Shu Wang JianNa Li Yihong Cao JingWei Gu YuanFeng Wang ShiGuo Chen | 2022 | Advanced Fiber Materials2022，4，1： | 1 |
| 3 | An overview of biofuel power generation on policies and finance environment,applied biofuels,device and performance显示文摘The prices of fossil fuels,the gap between energy supply and demand,energy security,environmental issues,and the reduction of greenhouse gas emissions commonly promote the development of biomass power generation in China.Compared to direct biomass combustion power generation and biogas power generation,liquid biofuel power generation has better application potential.Policies and finance environment of countries and organizations have promoted the extensive application of biofuel power generation in recent years,especially in China.Evaluation of internal combustion engine,gas turbine and fuel cell on the stationary power station and mobile generation shows that gas turbine is the main generator-set,the fuel cell is the fastest-growing and future generator-set,while the engine is the first choice in transport and low power generation field.As the second,third and fourth generation biofuels,biomethanol,bioethanol,biodiesel and others have been researched and widely used in power generation.In addition,power generation performance and emissions have been improved to some extent after biofuels supplying.For the future,combined heat and power(CHP)generation and integrated gasification combined cycle(IGCC)is imperative development trends of power generation for higher energy and exergy efficiency.CHP based on the various generating facilities will be the next choice and direction of energy use trends for transport. | Yang Yang Zhilin Tian Yuanfeng Lan Shu Wang Hao Chen | 2021 | Journal of Traffic and Transportation Engineering(English Edition)2021，8，4： | 1 |
