| 1 | Multi-objective regulation in autohydrolysis process of corn stover by liquid hot water pretreatment显示文摘Increasing reducing sugars(xylose and glucose) yield for bioethanol from corn stover depends strongly on optimization of pretreatment conditions. The optimum reaction conditions of two-stage liquid hot water(LHW) pretreatment based on total sugars yield were investigated. Under optimal conditions, the recovery of glucose of corn stover after two-stage LHW pretreatment and 72 h enzymatic digestion, reached 89.55%. In addition, acetic acid-rich spent liquor pretreatment and one-stage LHW pretreatment have been carried out to make comparisons with two-stage LHW treatment. Glucose yield 89.55% is superior to the recovery 83.38% using acetic acidrich spent liquor pretreatment or 80.58% using one-stage LHW pretreatment. The production of total sugars was increased by 7.8% when compared with one-stage pretreatment. Moreover, the structural features of the treated corn stover solid residues were also investigated by XRD and SEM technology in order to clarify the effects of the reaction on corn stover. The results indicated that the two-stage LHW pretreatment was an effective pretreatment method of corn stover to get most massive resource utilization, and it could be successfully applied to corn stover. | Huisheng Lü Xingfang Shi Yonghui Li Fanmei Meng Shuangyan Liu Li Yan | 2017 | Chinese Journal of Chemical Engineering2017，25，4： | 6 |
| 2 | Adsorption equilibrium for Z-ligustilide on C18-bonded silica from supercritical carbon dioxide显示文摘Adsorption equilibrium is of great importance for the preparative supercritical fluid chromatography(pre-SFC) in defining supercritical adsorption behavior and the industrial amplification.This paper presents adsorption isotherms of Z-ligustilide from supercritical carbon dioxide(SC-CO_2) on C18-bonded silica.Adsorption behavior was studied at 305.15 K,313.15 K and 323.15 K with SC-CO_2 density varying from 0.687 g·cm^(-3) to0.863 g·cm^(-3) with the elution by characteristic points(ECP) method.The adsorption amount of Z-ligustilide from SC-CO_2 on C18-bonded silica decreased with the increasing density of the mobile phase as well as the increasing temperature.Adsorption equilibrium data were fitted by Langmuir and Freundlich isotherm models,and the Langmuir isotherm model performed better for describing the whole adsorption process on the column.The monolayer saturation adsorption capacity of Z-ligustilide is in the range of 3.0 × 10^(-4) mg·cm^(-3) to5.5 × 10^(-4) mg·cm^(-3) with an average value of 4.0 × 10^(-4) mg·cm^(-3). | Huisheng Lü Shuangyan Liu Yonghui Li Fanmei Meng Dawei Yao Xufei Mo | 2016 | Chinese Journal of Chemical Engineering2016，24，12： | 1 |

| 9 | 4-27 Study the Rectification Effect of Single Graphene/PET Nanopore显示文摘Solid state nanopores or nanochannels prepared in polymer[1;2]and semiconductor films[3]have shown interesting transport phenomena,because of their diameters at the nanoscale and positive or negative charges on their walls.Graphene is an ideal material for developing solid state nanopores not only due to its atomic scale thickness,high mechanical strength and chemical stabilities but also because of the impermeability of the pristine single layer graphene to all atoms and molecules except protons[4].As the single Graphene/PET(G/PET)nanopore is the elementary building block for nanoporous membrane,the understanding and control of its individual ionic transport properties are also crucial in protein separation,water desalination,and bio-molecule detection using arrays of identical nanopores.Here,the single G/PET nanopore was successfully prepared by using ion irradiation technology and asymmetric etching method[5]and the corresponding ionic transport properties were investigated in detail. | Yao Huijun Xie Lu Cheng Yaxiong Duan Jinglai Chen Yonghui Lü Shuangbao Sun Youmei Liu Jie | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 10 | 4-28 Surface Modification and Damage of MeV-Energy Heavy Ion Irradiation on Gold Nanowires显示文摘Recently,the irradiation effects in nanomaterials have been a hot topic in nanoscience.Although irradiationinduced damages have been studying for a long time,very limited research has been performed on the damages induced by MeV-energy heavy ions in gold nanowires(NWs).In this work,we report a study of the irradiation effects on single crystalline gold NWs,which are fabricated electrochemically in the etched ion track templates.The as-prepared gold NWs on the Au/Cu substrate were characterized by SEM after dissolving the polycarbonate(PC)template,as shown in Fig.1(a).Gold NWs with diameters from 20 to 90 nm were fabricated to study the size dependence of irradiation damage induced by the heavy ions.To guarantee that the different NWs could obtain the same irradiation fluence,the NWs with different diameters were mixed together and transferred to the TEM grid,as shown in Fig.1(b). | Cheng Yaxiong Yao Huijun Duan Jinglai Xu Lijun Zhai Pengfei Lü Shuangbao Chen Yonghui Khan Maaz Mo Dan Sun Youmei Liu Jie | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 11 | Adsorption equilibria of paeoniflorin and albiflorin on cyano-silica column from supercritical carbon dioxide/ethanol显示文摘Adsorption equilibria of paeoniflorin and albiflorin on a cyano-silica column(CN column) from the solution of supercritical carbon dioxide(scCO2) modified with ethanol were studied. The adsorption capacity at 308.15 K,313.15 K, 318.15 K and 323.15 K under pressures corresponding to carbon dioxide/ethanol densities from0.347 g·cm^-3 to 0.662 g·cm^-3 were determined using the elution by characteristic point method(ECP). The effects of temperature and pressure on the solute loading were investigated. The results showed that the lower the temperature, the higher the adsorption capacity. With the decrease of density of scCO2, the adsorption capacity strengthens. The maximum adsorption capacity of paeoniflorin(albiflorin) on the CN column was15.24 mg·ml^-1(31.14 mg·ml^-1) in the range of 0–1.84 mg·ml^-1(0–1.67 mg·ml^-1) of paeoniflorin(albiflorin)standard solution. The adsorption capacity of albiflorin was twice as much as that of paeoniflorin under the same conditions. Adsorption data of paeoniflorin and albiflorin could be well described by the Langmuir model and Freundlich model. Compared with the two model fitting results, the adsorption of paeoniflorin and albiflorin belonged to the monolayer adsorption under conditions of 308.15–323.15 K and 10–17 MPa. | Huisheng Lü Zhi Wang Zhongfeng Geng Yonghui Li Shuangyan Liu Jiatao Liu | 2019 | Chinese Journal of Chemical Engineering2019，27，4： | 0 |
| 12 | Optimization of hydrothermal pretreatment for co-utilization of xylose and glucose of cassava anaerobic residue for producing ethanol显示文摘The development of a process that could recover biofuel from industrial cellulose waste can not only reduce the negative environmental impacts by using fossil fuels, but also bring a green idea for the waste’s disposing. In this study, hydrothermal pretreatment was optimized for cassava anaerobic residue, a cellulosic waste from cassava ethanol industry, to co-utilize xylose and glucose for producing bioethanol. The effect of the main pretreatment conditions, namely, temperature, solid content and time, was explored for the highest recovery of xylose in prehydrolysate and glucose in enzymatic hydrolysate. The single factor experiment results showed that the conditions for maximum xylose recovery in prehydrolysate and glucose recovery in enzymatic hydrolysate were 60℃, 75 min, 10% solids and 160℃, 75 min, 10% solids, respectively. Whereafter, response surface methodology(RSM) was applied to further optimize the pretreatment conditions for the maximum theoretical ethanol production through utilizing both xylose and glucose. A treatment at 163℃, for 59 min and with 9.5%solids was found optimal, with the highest ethanol production of 20.2 mg·g^-1 raw material. Furthermore, in order to assess the impacts of the pretreatment on cassava anaerobic residue, the changes in crystallinity and morphology for untreated and pretreated solids were investigated. | Huisheng Lü Jinyi Zhou Jiatao Liu Chunliu Lü Feng Lian Yonghui Li | 2019 | Chinese Journal of Chemical Engineering2019，27，4： | 0 |
