| 1 | Catalytic microwave assisted pyrolysis of aspen显示文摘The effect of catalysts on the microwave pyrolysis of aspen pellets was studied.A range of chlorides,nitrates and metal-oxides were added at 2%of the aspen mass(air dry aspen pellet weight basis).Chlorides in particular were found to favor liquid yield,especially the yield of water phase residue.Average liquid yield with added chlorides was 41%mass of the total biomass input,compared to 35%mass without catalyst.Metal-oxides were found to favor pyrolysis heavy oil,and thus total oil yield,since the yield of light oils seemed to be fairly constant.Nitrates were found to favor pyrolysis gas production.Pure light oils and light oils blended with diesel were found to be a potential diesel fuel substitute. | Johannes Moen Changyan Yang Bo Zhang Hanwu Lei Kevin Hennessy Yiqin Wan Zhiping Le Yuhuan Liu Paul Chen Roger Ruan | 2009 | International Journal of Agricultural and Biological Engineering2009，2，4： | 5 |
| 2 | Effects of reaction temperature,time and particle size on switchgrass microwave pyrolysis and reaction kinetics显示文摘This study investigated microwave pyrolysis of switchgrass with particle sizes from 0.5 mm to 4 mm and determined the effects of reaction temperature and time on the yields of bio-oil,syngas,and bio-char.A prediction model was satisfactorily developed to describe the bio-oil conversion yield as a function of reaction temperature and time.Second-order reaction kinetics was also developed to model the switchgrass pyrolysis.Switchgrass with different particle sizes was found to be similarly pyrolyzed by microwave heating.The research results indicated that thermochemical conversion reactions can take place rapidly in large-sized switchgrass by using microwave pyrolysis.GC-MS analysis indicates that the bio-oil contained a series of important and useful chemical compounds:phenols,aliphatic hydrocarbons,aromatic hydrocarbons,and furan derivatives.These chemical compounds evolved were related to the pyrolysis conditions. | Rui Zhou Hanwu Lei James L.Julson | 2013 | International Journal of Agricultural and Biological Engineering2013，6，1： | 4 |
| 3 | Fractionation and characterization of bio-oil from microwave-assisted pyrolysis of corn stover显示文摘Bio-oil from thermochemical conversion of biomass is a complex mixture of polar and non-polar compounds,and cannot be used directly as a combustion engine fuel due to its low heating value,high viscosity,chemical instability,and incomplete volatility.Mixed-solvent extraction was developed to fractionate bio-oils from microwave-assisted pyrolysis of corn stover to produce light oil(a mixture of light and inflammable fuel oil components from bio-oil)with low viscosity and low combustion residue,and high value chemicals.Different fractions from bio-oil were characterized using GC/MS and TG,and a major chemical(hydroxy-butanedioic acid diethyl ester)was separated. | Changyan Yang Bo Zhang Johannes Moen Kevin Hennessy Yuhuan Liu Xiangyang Lin Yiqin Wan Hanwu Lei Paul Chen Roger Ruan | 2010 | International Journal of Agricultural and Biological Engineering2010，3，3： | 4 |
| 4 | Breakthrough Technologies for the Biorefining of Organic Solid and Liquid Wastes显示文摘有机固液废弃物包含大量能量、养分和水分,不应仅视其为废物。数十年来,人们一直对城市固体废物进行回收、堆制和燃烧,并从中提取能量和有价值的物质。污水的首要管理策略是治理和排放。随着技术的进步,通过新方法使利用固体废物和废水成为可能。考虑到废物特殊的化学、物理和生物性质,需要整合多种技术以使废物的能量和价值回收最大化。为此,生物炼制是完全利用废物中的能量和价值的一个合适的方法。研究证明,不可回收废弃物和生物固体可通过不同方法转化为可利用的热能、电能、燃料和化学品,并且液体废物或能帮助农作物和藻类的成长,为能量回收和食物生产提供不同的选择。本文针对有机固液废物提出新型生物炼制方案,这些废物来源于城市废料、食品和生物加工厂以及动物生产设施。四大新型突破性科技——真空辅助高温厌氧消化、扩展鱼菜共生系统、含油废物经甘油裂解制取生物柴油和微波辅助热化学转化,均可运用于生物炼制方案中,从而成功将废物转化,用以生产化学品、化肥、能量(沼气、合成气、生物柴油和生物油)、食物、饲料,得到干净的水并显著减少污染物的排放。 | Paul Chen Erik Anderson Min Addy Renchuan Zhang Yanling Cheng Peng Peng Yiwei Ma Liangliang Fan Yaning Zhang Qian Lu Shiyu Liu Nan Zhou Xiangyuan Deng Wenguang Zhou Muhammad Omar Richard Griffith Faryal Kabir Hanwu Lei Yunpu Wang Yuhuan Liu Roger Ruan | 2018 | Engineering2018，4，4： | 3 |

| 7 | Color development in an extrusion-cooked model system显示文摘Rice-glucose-lysine blend was extruded using a co-rotating twin-screw extruder.The effects of different extrusion conditions on the browning properties of extrudates were analyzed and compared using the CIE Lab system of measurement.Extrusion process variables included moisture content,screw speed,barrel temperature,and screw geometry.The influence of product temperature on the browning property of extrudates was significant(P<0.05).The color parameters were related to product temperature by a 4th degree polynomial(P<0.05).Hunter color scale values(L*,a*,b*,-L*a*/b*,Whiteness Index,and Yellowness Index)from extruded samples were analyzed to relate to extrusion process variables.Product temperature and browning properties were modeled and tested at various screw configurations and extrusion conditions.Product temperature and browning property models were verified using different screw geometries and other processing conditions with reasonable accuracy. | Hanwu Lei Roger Ruan R.Gary Fulcher Bernhard van Lengerich | 2008 | International Journal of Agricultural and Biological Engineering2008，1，2： | 1 |

| 18 | Processing and properties of rigid polyurethane foams based on bio-oils from microwave-assisted pyrolysis of corn stover显示文摘A new kind of rigid polyurethane(PU)foam was synthesized from the oil phase of bio-oils from microwave-assisted pyrolysis of corn stover.The recipes for the PU foams consisted of polyol-rich bio-oils,water as blowing agent,polyethylene glycol(PEG)as both polyol donor and plasticizer,diphenylmethane-4,4’-diisocyanate(polymeric MDI)as cross-linking agent,silicon-based surfactant,and tin-based catalyst.The mechanical properties of rigid foams were measured with universal testing machine(Instron4206).The effects of individual ingredients on the physical and mechanical properties of the foams were studied.It was found that water content,bio-oil content,and isocyanate dosage were important variables in making PU foams in terms of mechanical strength,density,and cellular structure Under optimal conditions,the compression strength of the prepared PU foams reached 1130 kPa with a density of 152.9 g/L.The results show that bio-oils are potential renewable polyol sources for making rigid PU foams. | Jianping Wu Yuanhua Wang Yiqin Wan Hanwu Lei Fei Yu Yuhuan Liu Paul Chen Lirong Yang Roger Ruan | 2009 | International Journal of Agricultural and Biological Engineering2009，2，1： | 0 |
| 19 | Liquefaction of corn stover using industrial biodiesel glycerol显示文摘Corn stover was liquefied using an industrial biodiesel glycerol as a liquefying agent at atmospheric pressure and low temperature.It was found that the liquefaction yield increased with increasing glycerol-to-corn stover ratios.Sulfuric acid,added as a catalyst,was found to improve liquefaction yield.The hydroxyl number,moisture content,acid number,pH value,viscosity,density,elemental composition,and higher heating value of the liquefied corn stover samples were determined.The liquefied corn stover showed a high hydroxyl number of 270-310 mg KOH/g.Fourier transform infrared spectroscopy(FTIR)results revealed the functional groups and confirmed the existence of the OH group in the liquefied corn stover,indicating that the liquefied corn stover is indeed a source of polyols and a potential chemical stock for the synthesis of polymers. | Yuanhua Wang Jianping Wu Yiqin Wan Hanwu Lei Fei Yu Paul Chen Xiangyang Lin Yuhuan Liu Roger Ruan | 2009 | International Journal of Agricultural and Biological Engineering2009，2，2： | 0 |
| 20 | Optimization of modified clean fractionation of prairie cordgrass显示文摘In this study,modified clean fractionation process was optimized for prairie cordgrass,with usage of alternative organic constituent-ethyl acetate.Other constituents of the solvent mixture included ethanol and water.Clean fractionation solvent was used in different proportions of the constituents.Process efficiency was determined by lignin recovery,solvent composition,as well as time and temperature applied to each sequential process.Glucose yield during enzymatic hydrolysis and overall pretreatment were calculated.Optimal conditions(125℃,37 min,with the solvent composition of ester:ethanol:water=32.5:22.5:45)yielded a 20%lignin recovery,38%glucose yield during enzymatic hydrolysis and 26%xylose recovery in aqueous fraction. | Iwona Cybulska Hanwu Lei James Julson Grzegorz Brudecki | 2012 | International Journal of Agricultural and Biological Engineering2012，5，2： | 0 |
