| 1 | Effect of nano-particle size on product distribution and kinetic parameters of Fe/Cu/La catalyst in Fischer-Tropsch synthesis显示文摘Effects of nano-particle size on hydrocarbon production rates and distributions for precipitated Fe/Cu/La catalysts in Fischer-Tropsch synthesis were investigated.Nano-structured iron catalyst was prepared by micro-emulsion method.The concept of two superimposed AndersonSchulz-Flory (ASF) distributions has been applied for the representation of the effects of reaction conditions and nano-particles size on kinetics parameters and product distributions.These results reveal that by reducing the particle size of catalyst,the break in ASF distributions was decreased.Also useful different kinetics equations for synthesis of C3 to C9 and C10 to C22 were determined by using α1 and α2 chain growth probabilities. | Ali Nakhaei Pour Mohammad Reza Housaindokht Sayyed Faramarz Tayyari Jamshid Zarkesh | 2010 | Journal of Natural Gas Chemistry2010，19，2： | 4 |
| 2 | Fischer-Tropsch synthesis by nano-structured iron catalyst显示文摘Effects of nanoscale iron oxide particles on textural structure,reduction,carburization and catalytic behavior of precipitated iron catalyst in Fischer-Tropsch synthesis(FTS) are investigated.Nanostructured iron catalysts were prepared by microemulsion method in two series.Firstly,Fe2O3 ,CuO and La2O3 nanoparticles were prepared separately and were mixed to attain Fe/Cu/La nanostructured catalyst(sep-nano catalyst);Secondly nanostructured catalyst was prepared by co-precipitation in a water-in-oil microemulsion method(mix-nano catalyst).Also,conventional iron catalyst was prepared with common co-precipitation method.Structural characterizations of the catalysts were performed by TEM,XRD,H2 and CO-TPR tests.Particle size of iron oxides for sep-nano and mix-nano catalysts,which were determined by XRD pattern(Scherrer equation) and TEM images was about 20 and 21.6 nm,respectively.Catalyst evaluation was conducted in a fixed-bed stainless steel reactor and compared with conventional iron catalyst.The results revealed that FTS reaction increased while WGS reaction and olefin/paraffin ratio decreased in nanostructured iron catalysts. | Ali Nakhaei Pour Mohammad Reza Housaindokht Sayyed Faramarz Tayyari Jamshid Zarkesh | 2010 | Journal of Natural Gas Chemistry2010，19，3： | 3 |
| 3 | 碳纳米管负载的钴催化剂在费托合成反应中的粒子尺寸效应(英文)显示文摘The effect of Co particle size on the Fischer-Tropsch synthesis(FTS) activity of carbon nanotube(CNT)-supported Co catalysts was investigated. Microemulsion(using water-to-surfactant molar ratios of 2 to12) and impregnation techniques were used to prepare catalysts with different Co particle sizes. Kinetic studies were performed to understand the effect of Co particle size on catalytic activity. Size-dependent kinetic parameters were developed using a thermodynamic method, to evaluate the structural sensitivity of the CNT-supported Co catalysts. The size-independent FTS reaction rate constant and size-independent adsorption parameter increased with increasing reaction temperature. The Polani parameter also depended on catalyst particle size, because of changes in the catalyst surface coverage. | Ali Nakhaei Pour Elham Hosaini Mohammad Izadyar Mohammad Reza Housaindokht | 2015 | 催化学报2015，36，8： | 3 |
| 4 | Kinetics studies of nano-structured iron catalyst in Fischer-Tropsch synthesis显示文摘Kinetic parameters of nano-structured iron catalyst in Fischer-Tropsch synthesis (FTS) were studied in a wide range of synthesis gas conversions and compared with conventional catalyst.The conventional Fe/Cu/La catalyst was prepared by co-precipitation of Fe and Cu nitrates in aqueous media and Fe/Cu/La nanostructure catalyst was prepared by co-precipitation in a water-in-oil micro-emulsion.Nano-structured iron catalyst shows higher FTS activity.Kinetic results indicated that in FTS rate expression,the rate constant (k) increased and adsorption parameter (b) decreased by decreasing the catalyst particle size from conventional to nano-structured.Since increasing in the rate constant and decreasing in the adsorption parameter affected the FTS rate in parallel direction,the particle size of catalyst showed complicated effects on kinetic parameters of FTS reaction. | Ali Nakhaei Pour Mohammad Reza Housaindokht Sayyed Faramarz Tayyari Jamshid Zarkesh | 2010 | Journal of Natural Gas Chemistry2010，19，4： | 2 |
| 5 | Deactivation studies of nano-structured iron catalyst in Fischer-Tropsch synthesis显示文摘A nano-structured iron catalyst for syngas conversion to hydrocarbons in Fischer-Tropsch synthesis(FTS) was prepared by micro-emulsion method.Compositions of bulk iron phase and phase transformations of carbonaceous species during catalyst deactivation in FTS reaction were characterized by temperature-programmed surface reaction with hydrogen(TPSR-H 2 ),and XRD techniques.Many carbonaceous species on surface and bulk of the nano-structured iron catalysts were completely identified by combined TPSR-H 2 and XRD spectra and which were compared with those recorded on conventional co-precipitated iron catalyst.The results reveal that the catalyst deactivation results from the formation of inactive carbide phases and surface carbonaceous species like graphite,and it will be increased when the particle size of iron oxides was reduced in FTS iron catalyst. | Ali Nakhaei Pour Mohammad Reza Housaindokht Sayyed Faramarz Tayyari Jamshid Zarkesh | 2010 | Journal of Natural Gas Chemistry2010，19，3： | 2 |
| 6 | Kinetics of the water-gas shift reaction in Fischer-Tropsch synthesis over a nano-structured iron catalyst显示文摘Based on formate and direct oxidation mechanisms,three Langmuir-Hinshelwood-Hougen-Watson (LHHW) kinetic models of the water-gasshift (WGS) reaction over a nano-structured iron catalyst under Fischer-Tropsch synthesis (FTS) reaction conditions were derived and compared with those over the conventional catalyst.The conventional and nanostructured Fe/Cu/La/Si catalysts were prepared by co-precipitation of Fe and Cu nitrates in aqueous media and water-oil micro-emulsion,respectively.The WGS kinetic data were measured by experiments over a wide range of reaction conditions and comparisons were also made for various rate equations.WGS rate expressions based on the formate mechanism with the assumption that the formation of formate is rate determining step were found to be the best. | Ali Nakhaei Pour Mohammad Reza Housaindokht Sayyed Faramarz Tayyari Jamshid Zarkesh | 2010 | Journal of Natural Gas Chemistry2010，19，4： | 2 |

| 11 | A new kinetic model for direct CO2 hydrogenation to higher hydrocarbons on a precipitated iron catalyst:Effect of catalyst particle size显示文摘The kinetic of the direct CO_2 hydrogenation to higher hydrocarbons via Fischer–Tropsch synthesis(FTS)and reverse water-gas shift reaction(RWGS) mechanisms over a series of precipitated Fe/Cu/K catalysts with various particle sizes was studied in a well mixed, continuous spinning basket reactor. The iron catalysts promoted with copper and potassium were prepared via precipitation technique in various alcohol/water mixtures to achieve a series of catalyst particle sizes between 38 and 14 nm. A new kinetic model for direct CO_2 hydrogenation was developed with combination of kinetic model for FTS reaction and RWGS equilibrium condition. For estimate of structure sensitivity of indirect CO_2 hydrogenation to higher hydrocarbons, the kinetic parameters of developed model are evaluated for a series of iron catalysts with various particle sizes. For kinetic study a wide range of syngas conversions have been obtained by varying experimental conditions. The results show that the new developed model fits favorably with experimental data. The values of activation energies for indirect CO_2 hydrogenation reaction are fall within the narrow range of 23–16 kJ/mol. | Ali Nakhaei Pour Mohammad Reza Housaindokht | 2017 | Journal of Energy Chemistry2017，26，3： | 1 |
