| 1 | Coupling non-isothermal trickle-bed reactor with catalyst pellet models to understand the reaction and diffusion in gas oil hydrodesulfurization显示文摘In this work,a trickle-bed reactor coupled with catalyst pellet model is employed to understand the effects of the temperature and catalyst pellet structures on the reaction-diffusion behaviors in gas oil hydrodesulfurization(HDS).The non-isothermal reactor model is determined to be reasonable due to non-negligible temperature variation caused by the reaction heat.The reaction rate along the reactor is mainly dominated by the temperature,and the sulfur concentration gradient in the catalyst pellet decreases gradually along the reactor,leading to the increased internal effectiveness factor.For the fixed catalyst bed volume,there exists a compromise between the catalyst reaction rate and effectiveness factor.Under commonly studied catalyst pellet size of 0.8-3 mm and porosity of 0.4-0.8,an optimization of the temperature and catalyst pellet structures is carried out,and the optimized outlet sulfur content decreases to 7.6 wppm better than the commercial level at 0.96 mm of the catalyst pellet size and 0.40 of the catalyst porosity. | Xingqiang Zhao Changfeng Yang Mengke Lu Yao Shi Gang Qian Xinggui Zhou Xuezhi Duan | 2020 | Chinese Journal of Chemical Engineering2020，28，4： | 1 |
| 2 | Transgenic rice homozygous lines expressing GNA showed enhanced resistance to rice brown planthopper显示文摘Mature seed-derived callo from two elite Chinese japonica rice (Oryza saliva L.) cultivars Eyi 105 and Ewan 5 were co-transformed with two plasmids, pWRG1515 and pRSSGNAl, containing the selectable marker hygromy-cin phosphotransferase gene (hpt), the reporter β-glu-curonidase gene (gusA) and the snowdrop (Galanthus nivalis) lectin gene (gna) via particle bombardment. 61 independent transgenic rice plants were regenerated from 329 bombarded calli. 79% transgenic plants contained all the three genes, revealed by PCR/Southern blot analysis. Western blot analysis revealed that 36 out of 48 gna-containing transgenic plants expressed GNA (75%) at various levels with the highest expression being approximately 0.5% of total soluble protein. Genetic analysis confirmed Mendelian segregation of transgenes in progeny. From the R2 generations whose R1 parent plants showing 3:1 Mendelian segregation patterns, we identified five independent homozygous lines containing and expressing all the three transgenes.

| 7 | Variation of rate of exserted stigma in P(T) GMS lines of rice显示文摘Rate of exserted stigmas(RES),ie.the ratio ofglumes with exserted stigmas to the total glumes isone of the most important characteristics which af-fects the out-crossing rate of its combinations.Six-teen P(T)GMS lines with different ecotypes wereused to study the variations of RES during their sta-ble sterile period in Wuhan from 1992-1993.Tenhealthy panicles were randomly selected at full an- | ZHANG Xiangguang and LU Xinggui,Food Grops Research Institute ,Hubei Academy of Agriculiutral,Sciences Wuhan 430064,China | 1995 | Chinese Rice Research Newsletter1995，3，3： | 0 |
| 8 | Understanding the effects of electrode meso-macropore structure and solvent polarity on electric double layer capacitors based on a continuum model显示文摘The structures of electrode meso-macropore and the solvent polarity are the crucial factors dominating the performance of the electric double layer capacitors(EDLCs),but their impacts are usually tangled and difficult to decouple and quantitate.Here the effects of electrode meso-macropore structure and solvent polarity on the specific capacitance of an EDLC are quantitatively investigated using a steady-state continuum model.The simulation results indicate the specific capacitances are significantly affected by the meso-macropore surface structure.The specific capacitances significantly decrease for both convex surface structures but obviously increase for both concave surface structures,with the increase of curvature radius from 1 to 20 nm.As for solvents,the polar solvent with high saturated dielectric permittivity improves the capacitance performance.Moreover,the electrode meso-macropore structure is of more concern compared with solvent polarity when aiming at enhancing the specific capacitance.These results provide fundamentals for the rational design of porous electrodes and polar electrolytes for EDLCs. | Haotian Lu Jinghong Zhou Yueqiang Cao Tongxin Shang Guanghua Ye Quan-Hong Yang Xinggui Zhou | 2022 | Chinese Journal of Chemical Engineering2022，，10： | 0 |
