| 1 | Simultaneous mineralization of CO_2 and recovery of soluble potassium using earth-abundant potassium feldspar显示文摘CO2 capture and storage(CCS) is an important strategy in combatting anthropogenic climate change.However,commercial application of the CCS technique is currently hampered by its high energy expenditure and costs.To overcome this issue,CO2 capture and utilization(CCU) is a promising CO2 disposal method.We,for the first time,developed a promising method to mineralize CO2 using earth-abundant potassium feldspar in order to effectively reduce CO2 emissions.Our experiments demonstrate that,after adding calcium chloride hexahydrate as an additive,the K-feldspar can be transformed to Ca-silicates at 800 C,which can easily mineralize CO2 to form stable calcium carbonate and recover soluble potassium.The conversion of this process reached 84.7%.With further study,the pretreatment temperature can be reduced to 250 C using hydrothermal method by adding the solution of triethanolamine(TEA).The highest conversion can be reached 40.1%.The process of simultaneous mineralization of CO2 and recovery of soluble potassium can be easily implemented in practice and may provide an economically feasible way to tackle global anthropogenic climate change. | XIE HePing WANG YuFei JU Yang LIANG Bin ZHU JiaHua ZHANG Ru XIE LingZhi LIU Tao ZHOU XiangGe ZENG HongMei LI Chun LU HouFang | 2013 | Chinese Science Bulletin2013，58，1： | 16 |
| 2 | The CO_2 absorption and desorption performance of the triethylenetetramine + N,N-diethylethanolamine + H_2O system显示文摘Post-combustion CO_2 capture(PCC) process faces significant challenge of high regeneration energy consumption.Biphasic absorbent is a promising alternative candidate which could significantly reduce the regeneration energy consumption because only the CO_2-concentrated phase should be regenerated. In this work, aqueous solutions of triethylenetetramine(TETA) and N,N-diethylethanolamine(DEEA) are found to be efficient biphasic absorbents of CO_2. The effects of the solvent composition, total amine concentration, and temperature on the absorption behavior, as well as the effect of temperature on the desorption behavior of TETA–DEEA–H2 O system were investigated. An aqueous solution of 1 mol·L-1 TETA and 4 mol·L-1 DEEA spontaneously separates into two liquid phases after a certain amount of CO_2 is absorbed and it shows high CO_2 absorption/desorption performance.About 99.4% of the absorbed CO_2 is found in the lower phase, which corresponds to a CO_2 absorption capacity of 3.44 mol·kg-1. The appropriate absorption and desorption temperatures are found to be 30 °C and 90 °C,respectively. The thermal analysis indicates that the heat of absorption of the 1 mol·L-1 TETA and 4 mol·L-1 DEEA solution is-84.38 kJ·(mol CO_2)-1 which is 6.92 kJ·(mol CO_2)-1 less than that of aqueous MEA. The reaction heat, sensible heat, and the vaporization heat of the TETA–DEEA–H2 O system are lower than that of the aqueous MEA, while its CO_2 capacity is higher. Thus the TETA–DEEA–H2 O system is potentially a better absorbent for the post-combustion CO_2 capture process. | Yaoyao Li Changjun Liu Richard Parnas Yingying Liu Bin Liang Houfang Lu | 2018 | Chinese Journal of Chemical Engineering2018，26，11： | 6 |
| 3 | DBU-based CO2 absorption-mineralization system: Reaction process,feasibility and process intensification显示文摘Amine-based carbon dioxide(CO2)capture is still limited by high desorption energy consumption.Fixing CO2 into carbonate is a safer and more permanent method.In this work,calcium oxide(CaO)is introduced to perform chemical desorption instead of thermal desorption on 1,8-diazabicyclo[5.4.0]undec-7-ene(DBU)aqueous solution after CO2 absorption.The X-ray diffraction(XRD)patterns of solid products show the formation of calcite calcium carbonate(CaCO3),which prove the feasibility of this method.The effects of reaction temperature,reaction time and Ca2+/CO32-molar ratios on the related reactions in CO2 absorption-mineralization process and CaCO3 precipitation are discussed,and purer CaCO3 is obtained by ultrasonic treatment.The CaCO3 content can be increased to 95.8%and the CO2 desorption ratio can achieve 80%by 30 min ultrasonic dispersion treatment under the conditions(40℃,180 min,Ca2+/CO32-molar ratio=1.0).After five cycles,DBU aqueous solution shows stable CO2 absorption and mineralization ability.Fourier transform infrared spectroscopy(FT-IR)spectra of the reaction process also indicate the regeneration of the solvent.Compared with thermal desorption,this process is exothermic,almost without no additional heat. | Cong Luo Kejing Wu Hairong Yue Yingying Liu Yingming Zhu Wei Jiang Houfang Lu Bin Liang | 2020 | Chinese Journal of Chemical Engineering2020，28，4： | 4 |
| 4 | Cryo-EM structure of full-length α-synuclein amyloid fibril with Parkinson’s disease familial A53T mutation显示文摘Dear Editor,α-Synuclein(α-Syn)forms amyloid fibrils accumulating in Lewy bodies(LB)and Lewy neuritis(LN);which is a common histological hallmark of Parkinson’s disease(PD)and other synudeinopathies.1 Moreover,α-syn amyloid fibrils spread in the patient's brain via cell-to-cell transmission,which accounts for the disease progression.2 Several single amino-acid mutations of αa-syn,including A53T,E46K,H50Q,G51D,A30P and A53E,have been identified from familial PD patients,which are causative to the early-onset pathology with different clinical symptoms. | Yunpeng Sun Shouqiao Hou Kun Zhao Houfang Long Zhenying Liu Jing Gao Yaoyang Zhang Xiao-Dong Su Dan Li Cong Liu | 2020 | Cell Research2020，30，4： | 2 |
| 5 | The quasi-activity coefficients of non-electrolytes in aqueous solution with organic ions and its application on the phase splitting behaviors prediction for CO_(2) absorption显示文摘CO_(2)capture with a low energy consumption is of important application significance for reducing CO_(2)emission.The phase-change absorbent developed in recent years shows its potential for low-energy CO_(2)capture.The unclear phase-splitting rule hinders the efficient development of CO_(2)phase-change absorbents.To predict phase-splitting behaviors of mono/poly-amine-organic solvent-water system with various concentrations,a quasi-activity coefficient was developed based on Debye&Mc Aulay equation and some Density function theory descriptors.Six models based on Debye&Mc Aulay equation were developed with different ion radius,descriptors or poly-amine-CO_(2)products.The phase-splitting boundary was drawn on the model with the best predictability.This quasi-activity coefficient would provide guidance for the phase-splitting systems development,especially for polyamines. | Xiaomeng Zhao Xingyu Li Changjun Liu Shan Zhong Houfang Lu Hairong Yue Kui Ma Lei Song Siyang Tang Bin Liang | 2022 | Chinese Journal of Chemical Engineering2022，35，3： | 1 |

| 7 | Jatropha curcas L. oil extracted by switchable solvent N, N-dimethylcyclohexylamine for biodiesel production显示文摘Biodiesel, which is a renewable and environmentally friendly fuel, has been studied widely to help remedy increasing environmental problems. One of the key processes of biodiesel production is oil extraction from oilseed materials. Switchable solvents can reversibly change from molecular to ionic solvents under atmospheric CO_2,and can be used for oil extraction. N, N-dimethylcyclohexylamine(DMCHA), a switchable solvent, was used to extract oil from Jatropha curcas L. oil seeds to produce biodiesel. The appropriate extraction conditions were:1:2 ratio of seed mass to DMCHA volume, 0.3–1 mm particle size, 200 r·min-1agitation speed, 60 min extraction time, and 30 °C extraction temperature. The extraction ratio was about 83%. This solvent extracted the oil more efficiently than hexane, and is much less volatile. By bubbling CO_2 under 1 atm and 25 °C for 5 h, the oil was separated, and DMCHA was recovered after releasing CO_2 by bubbling N_2 under 1 atm and 60 °C for 2 h. The residual solvent content in oil was about 1.7%. Selectivity of DMCHA was evaluated by detecting the protein and sugar content in oil. Using the oil with residual solvent to conduct transesterification process, the oil conversion ratio was approximately 99.5%. | Shanjin Zeng Chuandong Tao Richard Parnas Wei Jiang Bin Liang Yingying Liu Houfang Lu | 2016 | Chinese Journal of Chemical Engineering2016，24，11： | 1 |

| 10 | Production of glycerol carbonate using crude glycerol from biodiesel production with DBU as a catalyst显示文摘The biodiesel production technology catalyzed by 1,8-diazabicycloundec-7-ene(DBU)is developed in this work.Crude glycerol containing DBU and DBU/glycerol/CO_2(DGC)ionic compounds reacts directly with dimethyl carbonate(DMC)to produce high value-added glycerol carbonate(GC)catalyzed by DBU and DGC.The catalytic performance of DBU and DGC,as well as the kinetics of the reaction catalyzed by DBU,were investigated.The results show that DGC has a weak catalytic effect on the transesterification of glycerol and DMC.When the temperature is higher than 60°C,DGC catalyzes the reaction jointly with DBU,which is produced from the decomposition of DGC.DBU has a good catalytic effect on the reaction between glycerol and DMC,with 90%conversion of glycerol and 84%selectivity to GC under the following conditions:DMC-to-glycerol molar ratio of 3:1,4.0%DBU(based on glycerol mass),reaction time of 60 min,and reaction temperature of 40°C.The apparent kinetics results show that the activation energies are 30.95 kJ·mol^(-1)and 55.16 kJ·mol^(-1)for the forward and reverse GC generation reactions,respectively,and the activation energy of the decomposition reaction of GC to glycidol(GD)is 26.58 kJ·mol^(-1). | Ying Qing Houfang Lu Yingying Liu Changjun Liu Bin Liang Wei Jiang | 2018 | Chinese Journal of Chemical Engineering2018，26，9： | 0 |
| 11 | Biochemical and biophysical characterization of pathological aggregation of amyloid proteins显示文摘Protein amyloid fibrillation, a process of liquid to solid phase transition, is involved in the pathogenesis of a variety of human diseases. Several amyloid proteins including α-synuclein (α-syn), Tau, amyloid β (Aβ) protein, and TAR DNA-binding protein 43 kDa (TDP-43) form pathological fibrils and deposit in patient brains of different neurodegenerative diseases (NDs) such as Parkinson’s disease (PD), Alzheimer’s disease (AD) and Amyotrophic lateral sclerosis (ALS). Preparation and characterization of amyloid fibrils in vitro are essential for studying the molecular mechanism underlying the dynamic amyloid aggregation and its pathogenesis in diseases. In this protocol, we take PD-associated α-syn as an example, and describe amyloid protein purification and fibrillation approaches. We then introduce biochemical and biophysical characterization of amyloid fibrils by Thioflavin-T (ThT) fluorescence kinetics assay, transmission electron microscopy (TEM), atomic force microscopy (AFM) and multiple fibril stability measurement assays. The approaches described here are applicable to different amyloid proteins, and are of importance for further study on the structure determination of amyloid fibrils and their pathological function in cells and animal models. | Houfang Long Shuyi Zeng Yunpeng Sun Cong Liu | 2022 | Biophysics Reports2022，8，1： | 0 |

| 13 | Ball milling promoted direct liquefaction of lignocellulosic biomass in supercritical ethanol显示文摘In the present work,ball milling was applied for the pretreatment of lignocellulose to obtain high conversion and bio-oil yield in supercritical ethanol.Ball milling substantially decreased the crystallinity and particle size of lignocellulose,thereby improving its accessibility in ethanol solvent.An increased bio-oil yield of 59.2%was obtained for the ball milled camphor-wood sawdust at 300℃,compared with 39.6%for the original lignocellulose.Decreased crystallinity signifi-cantly benefited the conversion of the cellulose component from 60.8%to 91.7%,and decreased particle size was beneficial for the conversion of all components.The obtained bio-oil had a high phenolic content,as analyzed by gas chromatography-mass spectrometry.Methoxylation and retro-aldol condensation were observed during alcoholysis,and the reaction pathways of lignocellulose in supercritical ethanol were attributed to the action of free radicals. | Chunyan Yang Xiaoliang Yuan Xueting Wang Kejing Wu Yingying Liu Changjun Liu Houfang Lu Bin Liang | 2020 | Frontiers of Chemical Science and Engineering2020，14，4： | 0 |
