| 1 | Effects of ammonium exchange and Si/Al ratio on the conversion of methanol to propylene over a novel and large partical size ZSM-5显示文摘One type of ZSM-5 zeolite with large partical size was prepared and characterized by XRD, SEM, N2 adsorption-desorption, XRF, Py-IR and NH3-TPD techniques. Effects of ammonium exchange and SiO2/Al2O3 molar ratios on the reaction of methanol to propylene (MTP) over Na-ZSM-5 and H-ZSM-5 zeolites have been studied in a fixed-bed flow reactor under the operating conditions of T = 500 °C, P = 1 atm, and WHSV = 6 h-1. Ammonium exchange led to a rapid decrease in Na content for Na-ZSM-5 zeolite. The reaction results indicated that Na-ZSM-5 and H-ZSM-5 with different SiO2/Al2O3 molar ratios all exhibited high activity for methanol conversion. Ammonium exchange and the decreased SiO2/Al2O3 molar ratio of ZSM-5 zeolite led to an increase both in strong acid sites and weak acid sites. Na-ZSM-5 with high SiO2/Al2O3 molar ratio was favorable for the formation of propylene. The highest propylene selectivity (45.9%) was obtained over Na-ZSM-5 zeolite catalyst with SiO2/Al2O3 molar ratio of 220. | Ruchao Wei Chunyi Li Chaohe Yang Honghong Shan | 2011 | Journal of Natural Gas Chemistry2011，20，3： | 12 |
| 2 | Hierarchical ZSM-11 with intergrowth structures:Synthesis,characterization and catalytic properties显示文摘Hierarchical ZSM-11 microspheres with intercrystalline mesoporous properties and rod-like crystals intergrowth morphology have been synthesized using a spot of tetrabutylammonium as a single template.XRD,FTIR,SEM,TEM and N2 adsorption analysis revealed that each individual particle was composed of nanosized rod crystals inserting each other and the intercrystalline voids existing among rods gave a significant mesopore size distribution.Steam treatment result demonstrated the excellent hydrothermal stability of samples.Various crystallization modes including constant temperature crystallization (one-stage crystallization) and two-stage temperature-varying crystallization with different 1st stage durations were investigated.The results suggested that the crystallization modes were mainly responsible for the adjustable particle size and textural properties of samples while the small amount of tetrabutylammonium bromide was mainly used to direct the formation of both ZSM-11 framework and its intergrowth morphology.Furthermore,the performance of optimal ZSM-11 as an active component for the catalytic pyrolysis of heavy oil was also investigated.Compared with the commercial pyrolysis catalyst,the hierarchical ZSM-11 catalyst exhibited a high selectivity to desired products(LPG+gasoline+diesel),as well as a much lower dry gas and coke yield,plus a high selectivity and yield of light olefins(C=3 C=4)and very poor selectivity to benzene.Therefore,fully open micropore-mesopore connectivity would make such hierarchically porous ZSM-11 zeolites very attractive for applications in clean petrochemical catalysis field. | Qingjun Yu Chaoyue Cui Qiang Zhang Jing Chen Yang Li Jinpeng Sun Chunyi Li Qiukai Cui Chaohe Yang Honghong Shan | 2013 | Journal of Energy Chemistry2013，22，5： | 10 |
| 3 | Effects of Temperature and Catalyst to Oil Weight Ratio on the Catalytic Conversion of Heavy Oil to Propylene Using ZSM-5 and USY Catalysts显示文摘实际操作在 FCC 由重油的催化变换学习丙烯的生产的规则是有用的(液体催化裂开) 。产品的分发和丙烯的收益上的温度和 C/O 比率(给重量比率上油的催化剂) 的效果与二模型催化剂在一个微反应堆单位上被调查,也就是, ZSM-5/Al2O3 和 USY/Al2O3,和 Fushun 真空瓦斯油(VGO ) 被用作化工物品。在 ZSM-5 催化剂上的重油的变换能比得上在高温和高 C/O 比率的 USY 催化剂的。用 ZSM-5 平衡催化剂的重油的变换的率与在一般 FCC 条件下面的 USY 平衡催化剂相比是更低的,这能被归因于 ZSM-5 平衡催化剂的差的蒸气能力。在 USY 和 ZSM-5 的毛孔拓扑学的差别是为什么的原因为上述二催化剂的主要产品是不同的,也就是汽油和液体石油气体(LPG ) repspectively。那么 LPG 选择,特别丙烯选择,如果 USY 为最大化丙烯的生产被增加进 FCC 催化剂,可以衰退。增加 C/O 比率比二模型催化剂的温度的增加是为 LPG 产量的增加的最节俭的方法,因为轻油的损失是在以前的案例中的更少。在 HTC (氢转移系数) 和丙烯的收益之间有反的关联,并且限制氢转移反应是在增加 ZSM-5 催化剂的丙烯的收益的更重要的措施。ZSM-5/Al2O3 的乙烯收益更高,但是当 ZSM-5 催化剂被使用时,有低价值的气体的副产品没被提高。而且为 LPG 和结束产品,弄干气体和焦炭,他们他们的收益依赖的反应对条件的范围是不同的,并且结束产品的比 LPG 的更严重。最大化 LPG 和丙烯并且限制干燥气体和焦炭能是经由在产量对 LPG 敏感的反应条件的范围之中增加反应条件的严厉完成的两个,因此是清楚的。给词调音:液体催化裂开;重油;丙烯;温度;催化剂将给重量比率上油;ZSM-5; | Xiaohong Li Chunyi Li Jianfang Zhang Chaohe Yang Honghong Shan | 2007 | Journal of Natural Gas Chemistry2007，16，1： | 10 |
| 4 | A high-surface-area silicoaluminophosphate material rich in Brnsted acid sites as a matrix in catalytic cracking显示文摘A transparent gel-like mesoporous silicoaluminophosphate material (SAP) with a Si/Al molar ratio of 20 was synthesized by hydrothermal method. The physicochemical features of SAP were characterized by XRD, XRF, BET, SEM and FT-IR spectroscopy of pyridine adsorption techniques. The results indicated that incorporation of phosphorus (P) into aluminasilica system altered the basic textural characteristics of aluminasilica. Especially after hydrothermal treatment, the material with large special surface area (up to 492 m 2 /g) exhibited a good performance on hydrothermal stability. Moreover, the phosphorus modifier can not only increase the amount of Bro¨nsted acidic sites (up to 48.44 μmol/g) and the percentage of weak acidic sites in total acidic sites, but also regulate the acid type, such as the ratio of B/L (Bro¨nsted acid/Lewis acid) increases to 1.15. The performances of samples as matrices for the catalytic cracking of heavy vacuum gas oil (VGO) were investigated. At 520 C, the catalysts showed much higher gasoline and diesel oil yields achieving to 45.59 wt% and 19.20 wt%, respectively, and lower coke selectivity (2.86%) than conventional FCC matrices, such as kaolin and amorphous silica-alumina. | Shaoiun Xu Qiang Zhang Zhaoxuan Feng Xiaojing Meng Tongyu Zhao Chunyi Li Chaohe Yang Honghong Shan | 2012 | Journal of Natural Gas Chemistry2012，21，6： | 8 |
| 5 | Synergistic effect of W and P on ZSM-5 and its catalytic performance in the cracking of heavy oil显示文摘In order to develop the conversion of heavy oil with a high yield of propylene in the catalytic cracking process, ZSM-5 zeolite was modified by tungsten and phosphorus, which was proved to be an effective method. Characterization results show that the improvement of catalytic performance could be correlated to the interaction of phosphorus and tungsten species on ZSM-5. P inhibited the aggregation of tungsten species on ZSM-5 and was conductive to convert the tungsten species with octahedral coordination into tetrahedral coordination. And this ultimately led to that more acid sites were reserved after hydrothermal treatment in the tungsten and phosphorus co-modified ZSM-5 catalyst.Phosphorus species played an important role to restrain the dehydrogenation activity of tungsten. In addition, a model reflecting the interaction between tungsten species and ZSM-5 framework was proposed. | Dongmin Han Nannan Sun Jianwei Liu Chunyi Li Honghong Shan Chaohe Yang | 2014 | Journal of Energy Chemistry2014，23，4： | 5 |
| 6 | Synthesis, Characterization and Evaluation of Sulfur Transfer Catalysts for FCC Flue Gas显示文摘In this work, Zr-M(M=Cu, Mn, Ce) type sulfur transfer agent was prepared by impregnation method. Under the condition similar to that in the regenerator of FCC units, the influence of different active metal components and their contents on sulfur transfer agent were investigated. Moreover, the crystalline structure of sulfur transfer agent was characterized by X-ray diffraction(XRD) and Fourier transforms infrared spectroscopy(FT-IR). The result showed that the Zr-Mn sulfur transfer agent could effectively reduce the SO2 content in FCC regenerator flue gas, featuring high SO2 adsorption capacity. The sulfur transfer agent was inactivated in 40—60 min during the test. In the course of reduction reaction, after several reaction cycles, the formation of SO2 ceased and only H2 S was detected as the reduction product. | Jiang Ruiyu Shan Honghong Zhang Jiling Yang Chaohe Li Chunyi | 2014 | China Petroleum Processing & Petrochemical Technology2014，16，2： | 5 |
| 7 | Effects of Cs-substitution and partial reduction on catalytic performance of Keggin-type phosphomolybdic polyoxometalates for selective oxidation of isobutane显示文摘The catalytic performance of Cs-substituted phosphomolybdic salts was studied for selective oxidation of isobutane. The results of activity tests revealed that 360 °C was the optimal reaction temperature. It was demonstrated that oxidizing sites not only took dominating part in the activation of isobutane, but also influenced the product distribution. Besides, appropriate Cs addition led to moderate acidity of catalysts, favoring the selectivity to desired products. Furthermore, to obtain partially reduced catalysts, different calcination atmospheres were investigated and certain proportion of Mo^(5+) produced during calcination was crucial for the redox reaction. The catalyst calcined in N_2 showed the highest yield of MAA(7.0%). Fe-substitution enhanced the activity of catalysts by rapid reoxidation of Mo^(5+). | Shizhe Liu Lu Chen Guowei Wang Jianwei Liu Yanan Gao Chunyi Li Honghong Shan | 2016 | Journal of Energy Chemistry2016，25，1： | 4 |
| 8 | Preparation and characterization of Mn/MgAlFe as transfer catalyst for SO_x abatement显示文摘A series of manganese-promoted MgAlFe mixed oxides, used as sulfur transfer catalysts, were prepared by acid-processed gelatin method and characterized by TGA-DTA, XRD, N2 adsorption-desorption and FT-IR techniques. It was found that the sulfur transfer catalysts with 0.5?3.0 wt% manganese showed its good dispersion in the precursor. The novel Mn/MgAlFe catalysts with 0.5?5.0 wt% manganese oxide showed a high oxidative adsorption rate and sulfur adsorption capacity, and 5.0 wt% Mn/MgAlFe sample was superior to the others for SO2 removal. Moreover, the presence of CO had no obvious effect on the adsorption activity of sulfur transfer catalysts for SO2 uptake. | Ruiyu Jiang Honghong Shan Chunyi Li Chaohe Yang | 2011 | Journal of Natural Gas Chemistry2011，20，2： | 4 |
| 9 | Studies on the preliminary cracking: The reasons why matrix catalytic function is indispensable for the catalytic cracking of feed with large molecular size显示文摘The matrix catalytic function when cracking the feed oil with large molecular size was systematically studied using three different catalyst configurations,including staged bed,partly mixed bed and completely mixed bed.Results showed that molecules in the feed oil with large molecular size indeed preferred to be first precracked on the matrix surface and then entered into the zeolite pores during the practical reaction process.Furthermore,the matrix catalytic function exhibited a great matrix-precracking ability to large feed molecules,which considerably increased the catalyst activity and the light oil selectivity.Besides the much better accessibility,the matrix-precracking ability was also from the similar capability to crack large feed hydrocarbons into the moderate fragments with that of the zeolite component.More interestingly,the interactions between the matrix catalytic function and the zeolite catalytic function made the catalyst not only exhibit much more catalytic advantages of the zeolite component,but also retain the matrix-precracking ability.As a result,the interactions enhanced the catalyst activity and improved the product distribution at the same time.The matrix catalytic function is indispensable for the catalytic cracking of feed with large molecular size,although the matrix component itself presented an inferior catalytic performance than the zeolite component did. | Bin Wang Nan Li Qiang Zhang Chunyi Li Chaohe Yang Honghong Shan | 2016 | Journal of Energy Chemistry2016，25，4： | 2 |

| 11 | Effect of Different Aromatic Fractions on Colloidal Property of Tahe Atmospheric Residue显示文摘Different amounts of FCC slurry oil and HVGO were added to Tahe atmospheric residue respectively.The colloidal stability and asphaltene agglomeration of atmospheric residue and mixed oils were characterized by means of the mass fraction normalized conductivity and the small-angle X-ray scattering technology(SAXS).The results indicated that the stability of Tahe atmospheric residue decreased with an increasing amount of these oil fractions.It was found that the decline of the colloidal stability was attributed to the component polarity difference between oil fractions and the atmospheric residue.Though the aromaticity of FCC slurry oil was higher than that of HVGO,the polarity of aromatics and resins of FCC slurry oil was lower than those of HVGO.So the degree of the colloidal stability was more seriously destroyed by FCC slurry oil.The dispersion of asphaltenes in Tahe atmospheric residue was changed by adding FCC slurry oil and HVGO.The particle size of asphaltenes increased along with the decline of the colloidal stability. | Yu Shuanglin Zhang Jiling Cheng Tao Rong Lili Xue Peng Shan Honghong | 2012 | China Petroleum Processing & Petrochemical Technology2012，14，3： | 1 |

| 13 | Characterization of Average Molecular Structure of Heavy Oil Fractions by ~1H Nuclear Magnetic Resonance and X-ray Diffraction显示文摘The chemical structure of heavy oil fractions obtained by liquid-solid adsorption chromatography was character-ized by 1 H nuclear magnetic resonance and X-ray diffraction.The molecular weight and molecular formula of asphaltene molecules were estimated by combining 1 H nuclear magnetic resonance and X-ray diffraction analyses,and were also ob-tained from vapor pressure osmometry and elemental analysis.Heteroatoms,such as S,N,and O atoms,were considered in the construction of average molecular structure of heavy oils.Two important structural parameters were proposed,including the number of alkyl chain substituents to aromatic rings and the number of total rings with heteroatoms.Ultimately,the av-erage molecular structures of polycyclic aromatics,heavy resins and asphaltene molecules were constructed.The number of α-,β-,γ-,and aromatic hydrogen atoms of the constructed average molecular structures fits well with the number of hydro-gen atoms derived from the experimental spectral data. | Ren Wenpo Yang Chaohe Shan Honghong | 2011 | China Petroleum Processing & Petrochemical Technology2011，13，3： | 1 |

| 15 | Molecular Simulations of FCC Dry Gas Components Adsorption in Zeolite Y显示文摘Adsorption of FCC dry gas components, hydrogen(H_2), nitrogen(N_2), methane(CH_4), ethane(C_2H_6) and ethylene(C_2H_4) in zeolite Y was studied by performing the Grant Canonical Monte Carlo(GCMC) simulations at 298K and 823K and under a pressure range up to 10 MPa. Simulation results were analyzed using the Langmuir model, which presented fitting of dry gas components adsorption to be suggested as the monolayer adsorption. C_2H_4 presented most single adsorption amount, which reached 7.63 mol/kg at 298K under a pressure of 200kPa. Thermodynamic parameters of the Gibbs free energy change, enthalpy change and entropy change were analyzed based on adsorption equilibrium constant obtained from the GCMC simulations. The results suggested that it was more favorable for C_2H_4 to be adsorbed in zeolite Y. Adsorption molecules were in ordered arrangement in the zeolite, and C_2H_4 exhibited a more orderly arrangement than other components. Additionally, a competition in the adsorption of a mixture of dry gas components was found, and supercages were the priority adsorption space. The competition was favorable to CH_4 and C_2H_6, and the competitive power was affected by temperature. | Ding Xue Liu Yibin Yang Chaohe Shan Honghong Chen Fangwen | 2016 | China Petroleum Processing & Petrochemical Technology2016，18，1： | 1 |
