| 1 | Reactive dividing wall column for hydrolysis of methyl acetate:Design and control显示文摘Reactive distillation and dividing wall column distillation are two kinds of effective separation technologies,and their integrated configuration,reactive dividing wall column(RDWC),presents attractive advantages.In this study,the rigorous simulation of RDWC for methyl acetate hydrolysis is performed,and sensitivity analysis is conducted to obtain the minimum reboiler duty.Then a comparison is made between the conventional process and RDWC process,and it shows that 20.1% energy savings can be achieved by RDWC process.In addition,the dynamic characteristic of RDWC is studied and an effective control strategy is proposed.The simple PI control scheme with three temperature loops can obtain reasonable control performance and maintain products at desired purities.It is proved that this RDWC process is an energy efficiency alternative with good controllability. | Lumin Li Lanyi Sun Delian Yang Wang Zhong Yi Zhu Yuanyu Tian | 2016 | Chinese Journal of Chemical Engineering2016，24，10： | 11 |
| 2 | Applicability and Generality of the Modified Grübler-Kutzbach Criterion显示文摘A generally applicable criterion for all mechanism mobility has been an active domain in mechanism theory lasting more than 150 years. It is stated that the Modified Grübler-Kutzbach criterion for mobility has been successfully used to solve the mobility of many more kinds of mechanisms, but never before has anyone proven the applicability and generality of the Modified Grübler-Kutzbach criterion in theory. In order to fill the gap, the applicability and generality of the Modified Grübler-Kutzbach Criterion of mechanism mobility is systematically demonstrated. Firstly, the mobility research background and the Modified Grübler-Kutzbach criterion are introduced. Secondly, some new definitions, such as half local freedom, non-common constraint space of a mechanism and common motion space of a mechanism, etc, are given to demonstrate the correctness and broad applicability of the Modified Grübler-Kutzbach criterion. Thirdly, the general applicability of the Modified Grübler-Kutzbach criterion is demonstrated based on screw theory. The mobilities of the classical DELASSUS mechanisms and a modern planar parallel mechanism, are determined through the Modified Grübler-Kutzbach criterion, which are as examples to show the practical application of the Modified Grübler-Kutzbach criterion. | LI Yanwen WANG Lumin LIU Jingfang HUANG Zhen | 2013 | Chinese Journal of Mechanical Engineering2013，26，2： | 6 |
| 3 | Optimization and Control of Extractive Distillation with Heat Integration for Separating Benzene/Cyclohexane Mixtures显示文摘In this work, the extractive distillation with heat integration process is extended to separate the pressure-insensitive benzene-cyclohexane azeotrope by using furfural as the entrainer. The optimal design of extractive distillation process is established to achieve minimum energy requirement using the multi-objective genetic algorithm, and the results show that energy saving for this heat integration process is 15.7%. Finally, the control design is performed to investigate the system's dynamic performance, and three control structures are studied. The pressure-compensated temperature control scheme is proposed based on the first two control structures, and the dynamic responses reveal that the feed disturbances in both flow rate and benzene composition can be mitigated well. | Li Lumin Tu Yangqin Guo Lianjie Sun Lanyi Tian Yuanyu | 2016 | China Petroleum Processing & Petrochemical Technology2016，18，4： | 3 |
| 4 | Design and Control of Self-Heat Recuperative Distillation Process for Separation of Close-Boiling Mixtures: n-Butanol and iso-Butanol显示文摘In order to explore the advantages of self-heat recuperative distillation(SHRD) process, the design and control of the SHRD process was studied for the separation of n-butanol and iso-butanol mixtures. The economic superiority of SHRD process is presented when a comparison on the total annual cost(TAC) of the conventional distillation process, the vapor recompression distillation process and the SHRD process was made. For the SHRD process, 37.74% and 11.35% savings of TAC can be achieved as compared to the conventional distillation process and vapor recompression distillation process, respectively. The dynamic characteristics of this promising SHRD sequence had been studied, and the dynamic responses demonstrated that 10% changes in both feed flow rate and feed composition can be well handled by the control strategy with dual-temperature control. It is proven that the SHRD system not only can provide economical savings but also can operate normally with good controllability. | Li Lumin Liu Yuliang Zhai Jian Sun Lanyi Tian Yuanyu | 2015 | China Petroleum Processing & Petrochemical Technology2015，17，4： | 3 |
| 5 | Design and Control of Thermally Coupled Reactive Distillation Sequence for Biodiesel Production显示文摘Decreasing petroleum reserves and growing alternative fuels requirements have promoted the study of biodiesel production. In this work, two thermally coupled reactive distillation designs for biodiesel production were investigated, and the sensitivity analysis was conducted to obtain the appropriate design values. The thermodynamic analysis and economics evaluation were performed to estimate the superiority of the thermally coupled designs over the base case. The proposed biodiesel production processes were simulated using the simulator Aspen Plus, and calculation results show that the exergy loss and economic cost in the two thermally coupled designs can be greatly reduced. It is found that the thermally coupled side-stripper reactive distillation design provides more economic benefits than the side-rectifier one. The dynamic performance of the thermally coupled side-stripper design was investigated and the results showed that the proposed control structure could effectively handle large feed disturbances. | Li Lumin Sun Lanyi Xie Xu Tian Yanan Shang Jianlong Tian Yuanyu | 2016 | China Petroleum Processing & Petrochemical Technology2016，18，2： | 2 |

| 7 | Design, Optimization and Control of Extractive Distillation for Separation of Ethyl Acetate-Ethanol-Water Mixture Using Ionic Liquids显示文摘In this work, the process simulation of pressure-swing distillation(PSD) and extractive distillation(ED) using ionic liquid(IL) 1-butyl-3-methylimidazolium acetate([bmim][OAc]) as the entrainer for separation of ethyl acetateethanol-water mixture is performed. The design parameters of the two distillation processes are optimized with the minimum total annual cost(TAC) serving as the objective function. The results show that the TAC saving of ED process is 35.27% in comparison with that of PSD process in the case of achieving the same purity and yield of ethyl acetate.In addition, the dynamic controllability of ED process is further studied. The traditional two-point temperature control structure is proposed for the ED process, and it works pretty well while taking into account the disturbances in both feed rate and feed composition. | Ma Shoutao Shang Xianyong Li Lumin Xue Changyong Li Jie Sun Lanyi | 2019 | China Petroleum Processing & Petrochemical Technology2019，21，1： | 2 |
| 8 | Isolation and Neuroprotective Activity of Phenolic Derivatives from the Marine-Derived Fungus Penicillium janthinellum显示文摘A new phenolic compound, 6-(2-acetyl-3,5-dihydroxybenzyl)-4-hydroxy-3-methyl-2H-pyran-2-one(1), along with other six known phenolic derivatives(2-7), were isolated from the mangrove rhizosphere fungus Penicillium janthinellum HK1-6 cultured in potato dextrose broth medium containing 30 g L^(-1) of natural sea salt. The structure of the new compound(1) was elucidated by comprehensive analysis of spectroscopic data including 1D and 2D NMR spectra. The proposed biosynthetic pathway of compound 1 was also studied in this research. Interestingly, a brominated phenolic derivative, aryl bromide(compound 8), was obtained from this fungal strain cultured in medium containing 30 g L^-1 of NaBr instead of natural sea salt. Compound 8 is proposed as a new natural product and formed through bromination of compound 7 when the fungus was cultured with NaBr. The neuroprotective effect of compound 1 on oxygen-glucose deprivation(OGD)-induced injury was investigated in rat spinal cord astrocytes. MTT assay demonstrated that compound 1 can attenuate OGD-induced cell viability loss in rat spinal cord astrocytes. | ZHENG Yaoyao CHEN Xu CHEN Lumin SHEN Li FU Xiumei CHEN Qiuxia CHEN Min WANG Changyun | 2020 | Journal of Ocean University of China2020，19，3： | 2 |
| 9 | Ca^(2+)-dependent TaCCD1 cooperates with TaSAUR215 to enhance plasma membrane H^(+)-ATPase activity and alkali stress tolerance by inhibiting PP2C-mediated dephosphorylation of TaHA2 in wheat显示文摘Alkali stress is a major constraint for crop production in many regions of saline-alkali land.However,little is known about the mechanisms through which wheat responds to alkali stress.In this study,we identified a calcium ion-binding protein from wheat,TaCCD1,which is critical for regulating the plasma membrane(PM)H^(+)-ATPase-mediated alkali stress response.PM H+-ATPase activity is closely related to alkali tolerance in the wheat variety Shanrong 4(SR4).We found that two D-clade type 2C protein phosphatases,TaPP2C.D1 and TaPP2C.D8(TaPP2C.D1/8),negatively modulate alkali stress tolerance by dephosphorylating the penultimate threonine residue(Thr926)of TaHA2 and thereby inhibiting PM H+-ATPase activity.Alkali stress induces the expression of TaCCD1 in SR4,and TaCCD1 interacts with TaSAUR215,an early auxin-responsive protein.These responses are both dependent on calcium signaling triggered by alkali stress.TaCCD1 enhances the inhibitory effect of TaSAUR215 on TaPP2C.D1/8 activity,thereby promoting the activity of the PM H^(+)-ATPase TaHA2 and alkali stress tolerance in wheat.Functional and genetic analyses verified the effects of these genes in response to alkali stress,indicating that TaPP2C.D1/8 function downstream of TaSAUR215 and TaCCD1.Collectively,this study uncovers a new signaling pathway that regulates wheat responses to alkali stress,in which Ca^(2+)-dependent TaCCD1 cooperates with TaSAUR215 to enhance PM H+-ATPase activity and alkali stress tolerance by inhibiting TaPP2C.D1/8-mediated dephosphorylation of PM H+-ATPase TaHA2 in wheat. | Minghan Cui Yanping Li Jianhang Li Fengxiang Yin Xiangyu Chen Lumin Qin Lin Wei Guangmin Xia Shuwei Liu | 2023 | Molecular Plant2023，16，3： | 1 |
| 10 | Nature-inspired porous multichannel carbon monolith:Molecular cooperative enables sustainable production and high-performance capacitive energy storage显示文摘The advancement of supercapacitors(SCs)is closely bound up with the breakthrough of rational design of energy materials.Freestanding and thick carbon(FTC)materials with well-organized porous structure is promising SC electrode delivering high areal capacitive performance.However,controllable and sustainable fabrication of such FTC electrode is still of great challenges.Inspired by natural honeycombs with cross-linked multichannel structure,herein,an innovative molecular-cooperative-interaction strategy is elaborately provided to realize honeycomb-like FTC electrodes.The nitrogen-doped porous carbon monolith(N-PCM)is obtained with advantages of interconnect pore structure and abundant nitrogen doping.Such strategy is based on naturally abundant molecular precursors,and free of pore-templates,expensive polymerization catalyst,and dangerous reaction solvent,rendering it a sustainable and cost-effective process.Systematic control experiments reveal that strong interactions among molecular precursors promise the structural stability of N-PCM during carbonization,and rational selection of molecular precursors with chemical blowing features is key step for well-developed honeycomb-like pore structure.Interestingly,the optimized sample exhibits hierarchical pore structure with specific surface area of 626.4 m^(2)g^(-1)and rational N-doping of 7.01 wt%.The derived SC electrode with high mass loading of 40.1 mg cm^(-2)shows an excellent areal capacitance of 3621 mF cm^(-2)at 1 mA cm^(-2)and good rate performance with 2920 mF cm^(-2)at 25 mA cm^(-2).Moreover,the constructed aqueous symmetric SC and quasi-solid-state SC produce high energy densities of 0.32 and 0.27 mWh cm^(-2),respectively.We believe that such a composition/microstructure controllable method can promote the fabrication and development of other thick electrodes for energy storage devices. | Mingquan Liu Feng Wu Lumin Zheng Xin Feng Ying Li Yu Li Ying Bai Chuan Wu | 2021 | InfoMat2021，3，10： | 1 |

| 15 | Bi-salt electrolyte for aqueous rechargeable aluminum battery显示文摘The exertion of superior high-energy density based on multivalent ions transfer of rechargeable aluminum batteries is greatly hindered by limited electrochemical stability window of typical water in salt electrolyte(Wi SE). Recently, it is reported that a second salt addition to the Wi SE can offer further suppression of water activities, and achieves a much wider electrochemical window compared with aqueous Wi SE electrolytes. Hence, we demonstrate a class of water in bi-salt electrolyte containing the trifluoromethanesulfonate(OTF), which exhibits an ultra-wide electrochemical window of 4.35 V and a very low overpotential of 14.6 m V. Moreover, the interface chemistry between cathode and electrolyte is also confirmed via kinetic analysis. Surprisingly, we find the electrolyte can effectively suppress Mn dissolution from the cathode, alleviate self-discharge behavior, and ensure a stable electrode–electrolyte interface based on the interface concentrated-confinement effect. Owing to these unique merits of water in bi-salt electrolyte, the AlxMnO_(2)·nH_(2)O material delivers a high capacity of 364 m Ah g;and superb long-term cycling performance > 150 cycles with a capacity decay rate of 0.37% per cycle with coulombic efficiency at ca. 95%. | Yaning Gao Yu Li Haoyi Yang Lumin Zheng Ying Bai Chuan Wu | 2022 | Journal of Energy Chemistry2022，31，4： | 0 |
| 16 | Surficial modification enabling planar Al growth toward dendrite-free metal anodes for rechargeable aluminum batteries显示文摘Al metal possesses ultrahigh theoretical volumetric capacity of 8,040 m Ah cm^(-3),and gravimetric capacity of 2,980 m Ah g^(-1),and thus is highly attractive for electrochemical energy storage.However,it suffers from several issues,such as the dendrite formation,during Al stripping-deposition cycling,which has been verified to account for the short circuit and limited cyclic performance.Herein,we use a facile and applicable method to in-situ reconstruct the Al anode surface with F-Al-O chemical bonds,which could preferentially induce the planar growth of Al along the interface plane,thus leading to the dendrite-free morphology evolution during the cycling.Benefiting from F-Al-O chemical bonds on the surface of Al anodes,long lifespan of symmetric cells can be realized even under 1 m A cm^(-2)and 1 m Ah cm^(-2).Coupling the F-Al anode with graphite-based cathodes,high-voltage dual-ion Al metal batteries can be achieved with long-term cycle stability up to 1,200 cycles(at 0.5 m A cm^(-2)),surpassing the counterparts using pristine Al metal anode.Furthermore,the effectiveness of this surficial modification strategy is also elucidated with the aid of theoretical calculation.This work provides novel insights on low-cost and facile strategies against the Al dendrite growth in aluminum batteries. | Wenhao Liu Yu Li Bo Long Haoyi Yang Lumin Zheng Ying Bai Feng Wu Chuan Wu | 2024 | Science China Chemistry2024，67，4： | 0 |
