| 2 | Enhanced catalytic performance of Cu-and/or Mn-loaded Fe-Sep catalysts for the oxidation of CO and ethyl acetate显示文摘The Fe-modi fied sepiolite-supported Mn–Cu mixed oxide(Cux Mny/Fe-Sep) catalysts were prepared using the co-precipitation method.These materials were characterized by means of the XRD,N_2 adsorption–desorption,XPS,H_2-TPR,and O_2-TPD techniques,and their catalytic activities for CO and ethyl acetate oxidation were evaluated.The results show that catalytic activities of the Cux Mny/Fe-Sep samples were higher than those of the Cu1/Fe-Sep and Mn2/Fe-Sep samples,and the Mn/Cu molar ratio had a distinct in fluence on catalytic activity of the sample.Among the Cux Mny/Fe-Sep and Cu1Mn2/Sep samples,Cu1Mn2/Fe-Sep performed the best for CO and ethyl acetate oxidation,showing the highest reaction rate and the lowest T50 and T90 of 4.4×10^(-6) mmol·g-1·s-1,110,and 140 °C for CO oxidation,and 1.9×10^(-6) mmol·g-1·s-1,170,and210 °C for ethyl acetate oxidation,respectively.Moreover,the Cu1Mn2/Fe-Sep sample possessed the best lowtemperature reducibility and the lowest temperature of oxygen desorption as well as the highest surface Mn^(4+)/Mn^(3+) and Cu^(2+)/CuO atomic ratios.It is concluded that factors,such as the strong interaction between the Cu or Mn and the Fe-Sep support,good low-temperature reducibility,and good mobility of chemisorbed oxygen species,might account for the excellent catalytic activity of Cu1Mn2/Fe-Sep. | Lisha Liu Yong Song Zhidan Fu Qing Ye Shuiyuan Cheng Tianfang Kang Hongxing Dai | 2017 | Chinese Journal of Chemical Engineering2017，25，10： | 2 |
| 3 | Medium-low temperature hydrothermal hydrolysis kinetic characteristics of concentrated wet microalgae biomass显示文摘To improve microalgae biomass utilization efficiency during biofuel production process,medium-low temperature hydrothermal hydrolysis pretreatment was adopted in this study.The pretreatment kinetic characteristics of concentrated wet microalgae Chlorella vulgaris biomass(50 g/L)under medium-low temperature hydrolysis(100°C-200°C)were experimentally investigated.The hydrothermal hydrolysis kinetics describing the coupled effects of temperature,initial pressure and retention time then were proposed using response surface methodology(RSM).The maximum carbohydrate yield reached 327.3 mg/g dried biomass under initial pressure of 4 MPa at reaction temperature of 150°C for 120 min.The maximum protein yield(321.5 mg/g dried biomass)was obtained under initial pressure of 4 MPa at reaction temperature of 200°C for 60 min.Based on the hydrothermal hydrolysis kinetic models,it was confirmed that temperature was the most important factor affecting both carbohydrate and protein release during hydrothermal hydrolysis process.Hydrothermal initial pressure and retention time were significant to carbohydrate release,but not to protein release.While,lipid was mainly distributed in microalgae residual and almost did not exist in supernatant(about 8.03 mg/g).And with assistance of mixed hexane and methanol(the ratio of hexane to methanol was 7:3),67.69%of microalgae lipid was extracted out from hydrothermal hydrolysed microalgae residual(123.3 mg/g dried biomass). | Ding Xiaojian Huang Yun Liao Qiang Fu Qian Xia Ao Xiao Chao Zhu Xun Reungsang Alissara Liu Zhidan | 2017 | International Journal of Agricultural and Biological Engineering2017，10，1： | 1 |

| 5 | Maize-soybean relay cropping increases soybean yield synergistically by extending the post-anthesis leaf stay-green period and accelerating grain filling显示文摘Relay cropping of Poaceae and Fabaceae promotes high yield and land-use efficiency by allowing a double harvest.However,it is difficult to increase yield synergistically because of the reduced photosynthetic abilities of legume leaves under the shade of graminoids.Leaf photosynthetic capacity in relay cropping systems is associated with ecological niche differentiation and photosynthetic compensation after restoration of normal light.We conducted a field experiment in southwest China in 2020–2021 to evaluate the effects of three cropping patterns:maize–soybean relay cropping(IMS),monoculture maize(MM),and monoculture soybean(SS),and N application levels:no N application(NN:0 kg N ha^(−1)),reduced N(RN:180 kg N ha^(−1)),and conventional N(CN:240 kg N ha^(−1)).Compared to monocropping,relay cropping increased the stay-green traits of maize and soybean by 13%and 89%,respectively.Relay cropping prolonged the leaf stay-green duration in the maize and soybean lag phase by almost 4 and 8 days,respectively.Relay cropping maize(IM)increased the leaf area index(LAI)by 79.4%to 88.5%under NN and 55.5%to 148%under RN.Relay cropping soybean(IS)increased the LAI from 115%to 437%at days 40 to 50 after anthesis.IM increased yield by 65.6%.IS increased yield by 9.7%.HI and system yield were at their highest values under RN.In the relay cropping system,reduced N application extended green leaf duration,increased photosynthesis inside the canopy at multiple levels,ultimately increases soybean yield synergistically. | Yiling Li Ping Chen Zhidan Fu Kai Luo Ping Lin Chao Gao Shanshan Liu Tian Pu Taiwen Yong Wenyu Yang | 2023 | The Crop Journal2023，11，6： | 0 |
