| 1 | Support effects on the chemical property and catalytic activity of Co-Mo HDS catalyst in sulfur recovery显示文摘Effects of carbon nanotubes (CNT) and alumina (γ-Al2O3) supports on the catalytic activities of hydrodesulfurization (HDS) process over CoMo catalyst have been studied. XRD results indicated that the main active phases in CNT and γ-Al2O3 supported Co-Mo catalysts are MoO2 and MoO3, respectively. The TPR results reveal that the reduction peak temperatures of the active species on CNT supported Co-Mo catalyst is lower than those on alumina supported Co-Mo catalyst, indicating that the CNT supports favor the reduction of active species. Catalytic evaluation results displayed that the sulfur content in the reaction products on the CNT supported Co-Mo catalyst is lower than that on the alumina supported Co-Mo catalyst if the HDS reaction was carried out at a temperature above 583 K. | Ali Nakhaei Pour Ali Morad Rashidi Kherolah Jafari Jozani Ali Mohajeri Payman Khorami | 2010 | Journal of Natural Gas Chemistry2010，19，1： | 7 |
| 2 | 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 |
| 3 | Partial oxidation of methane in Ba_(0.5)Sr_(0.5)Co_(0.8)Fe_(0.1)Ni_(0.1)O_(3-δ) ceramic membrane reactor显示文摘Ba0.5Sr0.5Co0.8Fe0.1Ni0.1O3δ(BSCFNiO) perovskite oxides were synthesized using a combined EDTA-citrate complexation method,and then pressed into disk and applied in a membrane reactor.The performance of the BSCFNiO membrane reactor was studied for partial oxidation of methane over Ni/α-Al 2 O 3 catalyst.The time dependence of oxygen permeation rate and catalytic performance of BSCFNiO membrane during the catalyst initiation stage were investigated at 850 C.In unsteady state,oxygen permeation rate,methane conversion and CO selectivity were closely related to the state of the catalyst.After 300 min from the initial time,the reaction condition reached to steady state and oxygen permeation rate were obtained about 11.7cm 3 cm 2 min 1.Also,the performance of membrane reactor was studied at the temperatures between 750 and 950 C.The results demonstrated good performance for the membrane reactor,as CH 4 conversion and CO selectivity permeation rate reached 98% and 97.5%,respectively,and oxygen permeation rate was about 14.5 cm 3 cm 2 min 1 which was 6.8 times higher than that of air-helium gradient.Characterization of membrane surface by SEM after reaction showed that the original grains disappeared on both surfaces exposed to the air and reaction side,but XRD profile of the polished surface membrane indicated that the membrane bulk preserved the perovskite structure. | Ensieh Ganji Babakhani Jafar Towfighi Zahra Taheri Ali Nakhaei Pour Majid Zekordi Ali Taheri | 2012 | Journal of Natural Gas Chemistry2012，21，5： | 4 |
| 4 | Ce-promoted Mn/Na_2 WO_4/SiO_2 catalyst for oxidative coupling of methane at atmospheric pressure显示文摘A series of Ce-promoted Mn-Na2WO4/SiO2 catalysts were prepared by incipient wetness impregnation method, and their catalytic performance for oxidative coupling of methane (OCM) was investigated at atmospheric pressure in a micro-quartz-tube reactor. The catalysts were characterized by X-ray diffraction (XRD), temperature program reduction (TPR) and BET surface area. Ce promoter increased surface area and Na2WO4 species dispersion, which enriched the amount of the surface species. In addition, Ce promoter increased the Na/W species reduction, but the reduction peak shifted to higher temperature. Stability test of 5wt%Ce catalyst indicated suitable performance and stability. The selectivity and yield of C2+ hydrocarbons after 50 h operation reached 65.5% and 19.6%, respectively, at 840 ℃ over 5wt%Ce-2wt%Mn-5wt%Na2WO4/SiO2 catalyst. | Seyed Mehdi Kamali Shahri Ali Nakhaei Pour | 2010 | Journal of Natural Gas Chemistry2010，19，1： | 3 |
| 5 | Deactivation studies of bifunctional Fe-HZSM5 catalyst in Fischer-Tropsch process显示文摘A physical mixture of alkali-promoted iron catalyst with binder based on Fischer-Tropsch synthesis and an acidic co-catalyst (HZSM5) for syngas conversion to hydrocarbons was studied in a fixed bed micro reactor. Deactivation data were obtained during the synthesis over a 1400 h period. The deactivation studies on iron catalyst showed that this trend followed the phase transformation Fe2.2C ( ε′) → Fe5C2 (χ) → Fe3C (θ), and the final predominant phase of the catalyst was Fe3C (θ). Deactivation of zeolite component in bifunctional catalyst may be caused by coking over the zeolitic component, dealumination of zeolite crystals, and migration of alkali promoters from iron catalyst under synthesis conditions. The deactivation rate of iron catalyst was also obtained. | Ali Nakhaei Pour Seyed Mehdi Kamali Shahri Yahya Zamani Mohammad Irani Shohreh Tehrani | 2008 | Journal of Natural Gas Chemistry2008，17，3： | 3 |
| 6 | Kinetics and product distribution studies on ruthenium-promoted cobalt/alumina Fischer-Tropsch synthesis catalyst显示文摘Hydrocarbon production rates and distributions on ruthenium promoted alumina supported cobalt Fischer-Tropsch synthesis (FTS) catalyst were studied by the concept of two superimposed Anderson-Schulz-Flory (ASF) distributions.The results indicated that the characterizing growth probabilities α1 and α2 were strongly dependent on reaction conditions.By increasing the H2 /CO partial pressure ratios and reaction temperatures,deviation from normal ASF distribution decreases and the double-α-ASF distribution changes into a straight line.Based on the concept of double-α-ASF distribution,a useful rate equation for the production of hydrocarbons under industrial reaction conditions is obtained. | Ahmad Tavasoli Ali Nakhaei Pour Masoumeh Ghalbi Ahangari | 2010 | Journal of Natural Gas Chemistry2010，19，6： | 3 |
| 7 | 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 |

| 10 | 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 |
| 11 | Enhancement of bimetallic Fe-Mn/CNTs nano catalyst activity and product selectivity using microemulsion technique显示文摘Bimetallic Fe-Mn nano catalysts supported on carbon nanotubes(CNTs) were prepared using microemulsion technique with water-to-surfactant ratios of 0.4-1.6. The nano catalysts were extensively characterized by different methods and their activity and selectivity in Fischer-Tropsch synthesis(FTS) have been assessed in a fixed-bed microreactor. The physicochemical properties and performance of the nanocatalysts were compared with the catalyst prepared by impregnation method. Very narrow particle size distribution has been produced by the microemulsion technique at relatively high loading of active metal. TEM images showed that small metal nano particles in the range of 3–7 nm were not only confined inside the CNTs but also located on the outer surface of the CNTs. Using microemulsion technique with water to surfactant ratio of0.4 decreased the average iron particle sizes to 5.1 nm. The reduction percentage and dispersion percentage were almost doubled. Activity and selectivity were found to be dependent on the catalyst preparation method and average iron particle size. CO conversion and FTS rate increased from 49.1% to 71.0% and 0.144 to 0.289 gHC/(gcat h), respectively. While the WGS rate decreased from 0.097 to 0.056 gCO2/(gcat h). C5+liquid hydrocarbons selectivity decreased slightly and olefins selectivity almost doubled. | Zahra Zolfaghari Ahmad Tavasoli Saber Tabyar Ali Nakhaei Pour | 2014 | Journal of Energy Chemistry2014，23，1： | 2 |
| 12 | 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 |
| 13 | 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 |
| 14 | Studies on product distribution of alkali promoted iron catalyst in Fischer-Tropsch synthesis显示文摘The dependencies of hydrocarbon product distributions of alkali promoted iron catalyst in Fischer-Tropsch synthesis have been studied. The concept of two superimposed Anderson-Schulz-Flory distributions has been applied for the representation of the effects of Mg, La and Ca promoters on product distributions. The FTS performance of the catalysts was tested in a fixed bed reactor under the conditions 563 K, 1.7 MPa, H2/CO = 1 and space velocities 4.86 and 13.28 nl h-1 gFe-1 . The results indicate that appropriate amounts of these promoters enhance the break in ASF distributions in the order Ca > Mg > La because of the rising of the catalyst surface basicity. | Ali Nakhaei Pour Masoud Zare Yahya Zamani | 2010 | Journal of Natural Gas Chemistry2010，19，1： | 2 |
| 15 | Effects of herbal extracts and compounds and pharmacological agents on pulmonary fibrosis in animal models:a review显示文摘Pulmonary fibrosis, a chronic inflammatory disease that occurs mainly in older adults, is a serious health threat with few effective treatment options. The etiological aspects of pulmonary fibrosis remain unknown, though some factors such as cigarette smoking, viral infections, surfactant protein polymorphisms, and chronic or high doses use of certain drugs are considered to be risk factors for the progression of pulmonary fibrosis. No standard treatments have been introduced in clinic yet. Although glucocorticoids and antioxidant drugs have been administered, the severe and broad-spectrum adverse effects of glucocorticoids limit their use. Efforts to identify novel therapeutic agents with improved safety profiles are therefore ongoing. In this review, the authors have described the effects of herbal extracts and compounds and certain pharmacological agents on pulmonary fibrosis in animal models. These effects indicate that herbs are a promising source of compounds that can play pivotal roles in the treatment of lung fibrosis. | hoda mojiri-forushani ali asghar hemmati mohammad amin dehghani ali reza malayeri hossein hassan pour | 2017 | Journal of Integrative Medicine2017，15，6： | 2 |
| 16 | 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 |

| 18 | Investigation of Environmental and Biological Effects of Rare Earth Elements (REEs) with a Special Focus on Industrial and Mining Pollutions in Iran:A Review显示文摘The present article is a review study on the types of rare earth elements(REEs),environmental and biological effects as well as the sources of emission of these elements as pollution in nature.The purpose of this study is to provide a vision in environmental planning and control of pollution caused by REEs.The evaluation of rare earth elements was studied in human life and its environmental and biological effects,which have particular importance and are entering the life cycle through industrial and mining pollution sources.Since mining activities intensify the dispersion of these elements in the environment and the existence of industrial factories located around urban drainage system plays a unique role in creating and spreading pollution caused by rare earth elements;As a result,two case studies were conducted on two mining and industrial areas.The first case is the Choghart mine in Yazd province as an example of mining pollution,and the second case study is performed on the Kor river as an example of industrial pollution which is caused by industrial activities around it,Then the results are well explained to show both two environments of litho and hydro.Due to this fact that produced environmental pollution can cause exchange pollutant compounds with the surrounding environment besides its long-lasting destructive effects;It can cause irreversible biological effects on living organisms.By targeting this evaluation,several techniques can be proposed to prevent the entry and dispersal of rare earth elements from pollution sources besides methods to reduce the damage of these elements to the ecosystem. | Aref Shirazi Adel Shirazy Amin Beiranvand Pour Ardeshir Hezarkhani Shayan Khakmardan | 2022 | Advances in Geological and Geotechnical Engineering Research2022，4，1： | 1 |
