| 1 | Biomass gasification technology:The state of the art overview显示文摘In the last decades the interest in the biomass gasification process has increased due to the growing attention to the use of sustainable energy. Biomass is a renewable energy source and represents a valid alternative to fossil fuels. Gasification is the thermochemical conversion of an organic material into a valuable gaseous product, called syngas, and a solid product, called char. The biomass gasification represents an efficient process for the production of power and heat and the production of hydrogen and second-generation biofuels.This paper deals with the state of the art biomass gasification technologies, evaluating advantages and disadvantages, the potential use of the syngas and the application of the biomass gasification. Syngas cleaning though fundamental to evaluate any gasification technology is not included in this paper since; in the authors' opinion, a dedicated review is necessary. | Antonio Molino Simeone Chianese Dino Musmarra | 2016 | Journal of Energy Chemistry2016，25，1： | 28 |

| 3 | Review of the biological and engineering aspects of algae to fuels approach显示文摘Current biofuel production relies on limited arable lands on the earth,and is impossible to meet the biofuel demands.Oil producing algae are alternative biofuel feedstock with potential to meet the world’s ambitious goal to replace fossil fuels.This review provides an overview of the biological and engineering aspects in the production and processing technologies and recent advances in research and development in the algae to fuels approach.The article covers biology,selection and genetic modification of algae species and strains,production systems design,culture media and light management,harvest and dewatering,downstream processing,and environment and economic assessment.Despite the many advances made over several decades,commercialization of algal fuels remains challenging chiefly because of the techno-economic constraints.Technological breakthroughs in all major aspects must take place before commercial production of algal fuels becomes economically viable. | Paul Chen Min Min Yifeng Chen Liang Wang Yecong Li Qin Chen Chenguang Wang Yiqin Wan Xiaoquan Wang Yanling Cheng Shaobo Deng Kevin Hennessy Xiangyang Lin Yuhuan Liu Yingkuan Wang Blanca Martinez Roger Ruan | 2009 | International Journal of Agricultural and Biological Engineering2009，2，4： | 9 |
| 4 | Clean coal technologies in Japan: A review显示文摘Coal is the primary fossil fuel most used in the world for the electricity generation, iron making, and cement/concrete and chemical production. However, utilization of coal also results in emissions of CO_2, SO_x, NO_x and other noxious compounds. The development of clean coal technology(CCT) is a main issue to maintain a clean environment. CCT in Japan is considered the highest level in the world. In this review, the developing CCTs in Japan including high efficiency combustion technologies, advanced gasification technologies, CO_2 recovery and utilization technologies, and flue gas cleaning technologies are introduced and discussed. It is expected to provide some new view-of-points for CCT development. | Guoqing Guan | 2017 | Chinese Journal of Chemical Engineering2017，25，6： | 9 |
| 5 | Effect of CO_2 and H_2O on gasification dissolution and deep reaction of coke显示文摘To more comprehensively analyze the effect of CO_2 and H_2O on the gasification dissolution reaction and deep reaction of coke, the reactions of coke with CO_2 and H_2O using high temperature gas–solid reaction apparatus over the range of 950–1250°C were studied, and the thermodynamic and kinetic analyses were also performed. The results show that the average reaction rate of coke with H_2O is about 1.3–6.5 times that with CO_2 in the experimental temperature range. At the same temperature, the endothermic effect of coke with H_2O is less than that with CO_2. As the pressure increases, the gasification dissolution reaction of coke shifts to the high-temperature zone. The use of hydrogen-rich fuels is conducive to decreasing the energy consumed inside the blast furnace, and a corresponding high-pressure operation will help to suppress the gasification dissolution reaction of coke and reduce its deterioration. The interfacial chemical reaction is the main rate-limiting step over the experimental temperature range. The activation energies of the reaction of coke with CO_2 and H_2O are 169.23 kJ ·mol-1 and 87.13 kJ·mol^(-1), respectively. Additionally, water vapor is more likely to diffuse into the coke interior at a lower temperature and thus aggravates the deterioration of coke in the middle upper part of blast furnace. | Zhi-yu Chang Ping Wang Jian-liang Zhang Ke-xin Jiao Yue-qiang Zhang Zheng-jian Liu | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，12： | 9 |
| 6 | Gasification kinetics of bulk coke in the CO2/CO/H2/H2O/N2 system simulating the atmosphere in the industrial blast furnace显示文摘The gasification characteristics and gasification kinetics of coke in complex CO2/CO/H2/H2O/N2 systems similar to the gas system of industrial blast furnace (BF) were studied by the method of isothermal thermogravimetric analysis. The experimental gas compositions and the corresponding temperature were chosen according to data reported for industrial BFs. The gasification behavior of coke was described by the Random Pore Model (RPM), Volumetric Model (VM), and Grain Model (GM). Results showed that the gas composition of the coke gasification zone in BF changes slightly and that the temperature is the most important factor affecting coke gasification. The lower activation energy of coke samples (Coke Reaction Index (CRI)>50) is due to the high Fe2O3 in the ash, lower degree of graphitization, and larger pore structure. In addition, the choice of kinetic model does not differ substantially in describing the gasification mechanism of coke in a BF. | Min-min Sun Jian-liang Zhang Ke-jiang Li Ke Guo Zi-ming Wang Chun-he Jiang | 2019 | International Journal of Minerals,Metallurgy and Materials2019，26，10： | 8 |
| 7 | Simulation of coal char gasification using O_(2)/CO_(2)显示文摘The authors proposed an integrated gasification fuel cell zero-emission system.The coal char gasification is discussed using high temperature and concentration of CO_(2) produced by solid oxide fuel cells and oxy-fuel combustion.The gasification is simulated by Aspen plus based on Gibbs free energy minimization method.Gasification model of pulverized coal char is computed and analyzed.Effects of gas flow rate,pressure,preheating temperature,heat losses on syngas composition,reaction temperature,lower heating value and carbon conversion are studied.Results and parameters are determined as following.The optimum O_(2) flow rate is 20 kg/h.The reaction temperature decreases from 1645 to 1329℃when the CO_(2)flow rate increases from 0 to 5 kg/h,the CO_(2) flow rate should be operated reasonably;lower heating value reduces and reaction temperature increases as the pressure increases;compared to the CO_(2) preheating,O_(2) preheating has greater influence on reaction temperature and lower heating value. | Haibin Li Yu Yu Minfang Han Ze Lei | 2014 | International Journal of Coal Science & Technology2014，1，1： | 7 |

| 9 | Kinetic study on catalytic gasification of a modified sludge fuel显示文摘A new type of mixture fuel, sludge-oil-coal agglomerate (SOCA), was catalytically gasified with steam in a thermobalance reactor under atmospheric pressure. All the four catalysts studied (K2CO3, CaO, NiO and Fe2O3) were found capable of enhancing the steam gasification rate and significantly increasing the conversion of carbon. The ranking of catalytic activity was found to be K2CO3 CaO > NiO > Fe2O3. A modified volumetric-reaction model in the literature was used to describe the conversion behavior of the steam gasification studied by evaluating the kinetic parameters. Expressions of the apparent gasification rates for SOCA were presented for the design of catalytic gasification processes. | Byungho Song Dookie Kim Seungjae Lee Seokku Jeon Youngtai Choi Yoonseop Byoun Woonsig Moon Joonghee Lee Honggun Kim Hongki Lee Joongpyo Shim | 2008 | Particuology2008，6，4： | 4 |
| 10 | Soot formation and oxidation during bio-oil gasification:experiments and modeling显示文摘A model is proposed to describe soot formation and oxidation during bio-oil gasification.It is based on the description of bio-oil heating,devolatilization,reforming of gases and conversion of both char and soot solids.Detailed chemistry (159 species and 773 reactions) is used in the gas phase.Soot production is described by a single reaction based on C2H2species concentration and three heterogeneous soot oxidation reactions.To support the validation of the model,three sets of experiments were carried out in a lab-scale Entrained Flow Reactor (EFR) equipped with soot quantification device.The temperature was varied from 1000 to 1400 C and three gaseous atmospheres were considered:default of steam,large excess of steam(H2O/C=8),and the presence of oxygen in the O/C range of 0.075–0.5.The model is shown to accurately describe the evolution of the concentration of the main gas species and to satisfactorily describe the soot concentration under the three atmospheres using a single set of identified kinetic parameters.Thanks to this model the contribution of different mechanisms involved in soot formation and oxidation in various situations can be assessed. | Younes Chhiti Marine Peyrot Sylvain Salvador | 2013 | Journal of Energy Chemistry2013，22，5： | 3 |

| 12 | Improvement Effect of Bioaugmentation with Phenol Degrading Bacteria on Lurgi Coal Gasification Wastewater Treatment显示文摘The improvement effect of bioaugmentation with phenol degrading bacteria( PDB) on pollutants removal and chemicals consumption was investigated in a full-scale Lurgi coal gasification wastewater( LCGW)treatment plant. Bioaugmentation with PDB applied in biological contact oxidation tank( BCOT) was carried out in summer to prevent the limitation of low temperature on the bacteria activity. After augmentation,the removal of COD and total phenol(TPh) was significantly enhanced,with efficiencies from 78.5% and 80% to 82.3% and 86.6% in BCOT,respectively. The improvement could also be detected in further processes,including anoxic-oxic,coagulation sedimentation and biological aerated filter,with COD and TPh removal efficiencies increment from 70.1%,24. 7% and 53. 4% to 73. 9%,29. 1% and 55. 9%,from 67. 1%,20% and 25% to 72.5%,25% and 32%, respectively. In addition, chemicals used for denitrification and coagulation sedimentation showed considerable reduction after bioaugmentation,with methanol,coagulant,coagulant aid and bleaching dosage from 100. 0,100. 0,80. 0 and 60. 0 mg/L to 85. 0,70. 6,57. 8 and 45.7 mg/L,respectively. Therefore,bioaugmentation with PDB can be a viable alternative for LCGW treatment plant in pollutants removal and chemicals saving. | Fang Fang Gang Wu Hongjun Han Mingnin Ma | 2017 | Journal of Harbin Institute of Technology(New Series)2017，24，6： | 3 |
| 13 | Thermophoresis effects on gas-particle phases flow behaviors in entrained flow coal gasifier using Eulerian model显示文摘A numerical model based on the Eulerian–Eulerian two-fluid approach is used to simulate the gasification of coal char inside an entrained flow gasifier. In this model, effects of thermophoresis of coal char particles are thoroughly investigated. The thermophoresis is due to the gas temperature gradient caused by absorpted heat of coal char gasification. This work, firstly, calculates the gas temperature gradient and thermophoretic force at1100 °C,1200 °C,1300 °C and 1400 °C wall temperatures. Then, the changes of particle volume fraction and velocity in the gasifier are studied in the simulation with thermophoresis or not. The results indicate that considering the particle thermophoresis has some effects on the calculation of particle volume fraction in the gasifier, especially at wall temperature of 1400 °C, and the maximum particle volume fraction variance ratio reaches up to 1.38% on wall surface of the gasifier. These effects are mainly caused by large gas temperature gradient along the radial direction of the gasifier. For the particle velocity, the changes are small but can be observable along radial direction of the gasifier, which has good agreement with the distributions of radial gas temperature gradient and thermophoretic force. These changes above may have certain effects on gasification reaction rates in this Eulerian model. So the change of gasification reaction rates in the simulation with thermophoresis or not is studied finally. | Chao Dai Fan Gu | 2017 | Chinese Journal of Chemical Engineering2017，25，6： | 3 |
| 14 | Simulation analysis of municipal solid waste pyrolysis and gasification based on Aspen plus显示文摘To predict and analyze the municipal solid waste(MSW)pyrolysis and gasification process in an updraft fixed bed more veritably and appropriately,numerical modeling based on Gibbs energy minimization was executed using the Aspen plus software.The RYield module was combined with the RGibbs module to describe the pyrolysis section,while the RGibbs module was used for the gasification section individually.The proposed model was used to forecast and analyze the target performance parameters including syngas composition,lower heating value(LHV)and carbon conversion rate under different conditions of the gasification temperatures,and ratios and types of gasifying agents.The results indicate that there is a good agreement between the experimental data and the simulated data obtained using this model.The predicted optimum gasification temperature is approximately 750°C,and the best ratio of water vapor as gasifying agent is around 0.4.The mixture of flue gas and water vapor has an economical and recycled prospect among four commonly used gasifying agents. | Na DENG Dongyan LI Qiang ZHANG Awen ZHANG Rongchang CAI Biting ZHANG | 2019 | Frontiers in Energy2019，13，1： | 3 |
| 15 | A O-dimensional cavity growth submodel for use in reactor models of underground coal gasification显示文摘Modelling of the underground coal gasification process is dependent upon a range of sub-models. One of the most important is the calculation of the cavity growth rate as a function of various operating conditions and coal properties. While detailed 1-dimensional models of coal block gasification are available, it is not easy to couple them directly with reactor models, which aim to simulate the complete process. In this paper, a O-dimensional cavity growth sub-model is presented. The model is based on the concept of a surface reaction and incorporates physics to account for moisture evaporation, water influx, coal pyrolysis, coal thermo-mechanical fragmentation and the build up of an ash layer on the char. The model is validated using measurements from laboratory experiments on coal cores and coal blocks. A comparison of calculated results from several UCG field trials shows that the model can provide good estimates of cavity growth rate for reasonable input parameters. Finally, simulation results of cavity growth in the combustion and gasification zones as a function of the bulk gas temperature, gas pressure, water influx rate, ash layer thickness and coal fragmentation behaviour are presented. | Greg Perkins | 2019 | International Journal of Coal Science & Technology2019，6，3： | 2 |
| 16 | Chemical looping gasification of maceral from low-rank coal: Products distribution and kinetic analysis on vitrinite显示文摘The product distribution and kinetic analysis of low-rank coal vitrinite were investigated during the chemical looping gasification(CLG)process.The acid washing method was used to treat low-rank coal,and the density gradient centrifugation method was adopted to obtain the coal macerals.By combining thermogravimetric analysis and online mass spectrometry,the influence of the heating rate and oxygen carrier(Fe2O3)blending ratio on product distribution was discussed.The macroscopic kinetic parameters were solved by the Kissinger-Akahira-Sunose(KAS)method,and the main gaseous product formation kinetic parameters were solved by the iso-conversion method.The results of vitrinite during slow heating chemical looping gasification showed that the main weight loss interval was 400–600℃,and the solid yield of sample vitrinite-Fe-10 at different heating rates was 64.30%–69.67%.When b=20℃·min^(-1),the maximum decomposition rate of vitrinite-Fe-10 was 0.312%min1.The addition of Fe2O_(3)reduced the maximum decomposition rate,but by comparing the chemical looping conversion characteristic index,it could be inferred that the chemical looping gasification of vitrinite might produce volatile substances higher than the pyrolysis process of vitrinite alone.The average activation energy of the reaction was significantly reduced during chemical looping gasification of vitrinite,which was lower than the average activation energy of 448.69 kJ·mol^(-1) during the pyrolysis process of vitrinite alone.The gaseous products were mainly CO and CO_(2).When the heating rate was 10℃·min^(-1),the highest activation energy for CH4 formation was 21.353 kJ·mol^(-1),and the lowest activation energy for CO formation was 9.7333 kJ·mol^(-1).This study provides basic data for exploring coal chemical looping gasification mechanism and reactor design by studying the chemical looping gasification process of coal macerals。 | Bo Zhang Bolun Yang Wei Guo Song Wu Jie Zhang Zhiqiang Wu | 2021 | Chinese Journal of Chemical Engineering2021，34，8： | 2 |
| 17 | Influence of coal properties on coal conversion processes-coal carbonization,carbon fiber production,gasification and liquefaction technologies:a review显示文摘Coal due to its relatively large quantities and wide distribution worldwide has generated renewed interest in research and development with the aim of establishing coal conversion technologies that are technically reliable,envi-ronmentally and economically feasible.It has proved to be a prominent energy source in emerging markets with increasing energy demand by accounting for the largest increase in the demand of energy amongst all other energy sources.Fur-thermore,with its higher mesophase content,coal tar is an appropriate raw material for precursors in the production of carbon fiber.However,whenever a material is put to use,it is important to be able to associate its properties to the behavioral characteristics during a conversion process so as to have a basis for opting for the material in a given process or adjusting the operating conditions in order to optimize the material utilization.Therefore,as with any other material,it is important to be able to relate the properties of coal to its utilization.A review was carried out on the influence of coal properties on four main utilization technologies:gasification,carbonization,liquefaction and carbon fibre production.Among several properties rank,type,mineral matter content,distribution of trace elements,structural composition and pore structure were found to be most influential on the behavior of coal during conversion processes. | K.P.Keboletse F.Ntuli O.P.Oladijo | 2021 | International Journal of Coal Science & Technology2021，8，5： | 2 |
| 18 | Systematic comparison of hydrogen production from fossil fuels and biomass resources显示文摘Fossil fuels are the main energy source to satisfy the worldwide energy demands.However,the energy demands are increasing and the supply of fossil fuels is decreasing,thus many countries are looking for other fuel sources.Differing from the traditional fuels,hydrogen is considered as one of the most promising energy sources due to its intrinsic features such as clean,efficient,safe and sustainable.Developing novel technologies for hydrogen production from renewable sources(such as biomass)becomes a core area for the investigation of hydrogen industry.Within this work,different pathways for hydrogen production including steam reforming,electrolysis,and biomass gasification have been systematically compared in terms of yield and cost.This comparison is unique since the systematic evaluation was conducted from many aspects for all the hydrogen production pathways,especially those by involving the biomass gasification that still lack of available literatures.The assessment methods involved energy analysis,exergy analysis and economic analysis.It was concluded that steam reforming remains the cheapest method of hydrogen production at 1.748$/kg,however,steam reforming is not an ideal process currently or for the future,gasification and electrolysis remains competitive with high yield but requires relatively high initial and annual expenditure.For biomass gasification,though its energy efficiency is lower than steam reforming,it has relatively higher mass yield,demonstrating the feasibility of this process for hydrogen production.Further for biomass gasification,the selection of correct feedstock is a key to maximize its yield,i.e.a yield of 82.47%is possible with corn stover fed gasification. | Kang Peng Gary Morrow Zhang Xiaolei Wang Tipeng Tan Zhongfu Jayant Agarwal | 2017 | International Journal of Agricultural and Biological Engineering2017，10，6： | 2 |
| 19 | Opposed multi-burner gasification technology:Recent process of fundamental research and industrial application显示文摘Opposed multi-burner(OMB)gasification technology is the first large-scale gasification technology developed in China with completely independent intellectual property rights.It has been widely used around the world,involving synthetic ammonia,methanol,ethylene glycol,coal liquefaction,hydrogen production and other fields.This paper summarizes the research and development process of OMB gasification technology from the perspective of the cold model experiment and process simulation,pilotscale study and industrial demonstration.The latest progress of fundamental research in nozzle atomization and dispersion,mixing enhancement of impinging flow,multiscale reaction of different carbonaceous feedstocks,spectral characteristic of impinging flame and particle characteristics inside gasifier,and comprehensive gasification model are reviewed.The latest industrial application progress of ultralarge-scale OMB gasifier and radiant syngas cooler(RSC)combined with quenching chamber OMB gasifier are introduced,and the prospects for the future technical development are proposed as well. | Fuchen Wang Guangsuo Yu Haifeng Liu Weifeng Li Qinghua Guo Jianliang Xu Yan Gong Hui Zhao Haifeng Lu Zhongjie Shen | 2021 | Chinese Journal of Chemical Engineering2021，34，7： | 2 |
| 20 | Effects of inherent alkali and alkaline earth metals on nitrogen transformation during steam gasification of Shengli lignite显示文摘This work evaluated the effects of inherent alkali and alkaline earth metals on nitrogen transformation during steam gasification of Shengli lignite at the temperature of 873-1173 K in a fluidized-bed/fixed-bed quartz reactor. The results indicated that the alkali metal Na and alkaline earth metals Ca, Mg in coal have different effects on inherent nitrogen transformation to NH3, HCN and char-N during the lignite steam gasification. Specifically during the steam gasification of Shengli lignite, Na and Ca, Mg not only catalyze the inherent nitrogen conversions to NH3, but also promote the secondary reactions of the nascent char-N as well as the generation of NH3 from the generated HCN, meanwhile they also inhibited the inherent nitrogen conversion to HCN and char-N. The presence of Na, Ca and Mg hindered the formation of oxidized nitrogen (N-X) functional groups, but enhanced pyridinic nitrogen (N-6) and quaternary nitrogen's (N-Q) formation in char. | Panpan Zheng Yonggang Wang Chen Liu Weijie Guo Lei Bai Xiao Hu Xiongchao Lin | 2019 | International Journal of Coal Science & Technology2019，6，2： | 2 |
