| 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 |

| 6 | 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 |
| 7 | Effect of acid density of HZSM-5 on the oligomerization of ethylene in FCC dry gas显示文摘The oligomerization of ethylene in FCC dry gas over HZSM-5 catalyst with different Si/Al2 ratios was studied. The effect of acid density of catalyst on the oligomerization of ethylene was discussed. By increasing the acid density of catalyst, ethylene conversion showed a linear increase, while the yields of olefins decreased when the acid density of catalyst exceeded 0.14 mmolNH3/g owing to a promotion of hydrogen transfer reaction. Through comparing the average distance between acid sites on catalyst with kinetic diameters of olefins, it was found that the dimerization of ethylene was not restrained by the sparse distribution of acid sites, while the hydrogen transfer reaction of C3 and C4 olefins was limited. On these bases, a conclusion is proposed that the dimerization of ethylene proceeded via Eley-Rideal mechanism, while the hydrogen transfer reaction of C3 and C4 olefins followed the Langmuir-Hinshelwood mechanism. | Xue Ding Shan Geng Chunyi Li Chaohe Yang Guohui Wang | 2009 | Journal of Natural Gas Chemistry2009，18，2： | 5 |
| 8 | 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 |
| 9 | The correlation between nitrogen species in coke and NO_x formation during regeneration显示文摘Nitrogen oxides(NO x)emission during the regeneration of coked fluid catalytic cracking(FCC)catalysts is an environmental issue.In order to identify the correlations between nitrogen species in coke and different nitrogencontaining products in tail gas,three coked catalysts with multilayer structural coke molecules were prepared in a fixed bed with model compounds(o-xylene and quinoline)at first.A series of characterization methods were used to analyze coke,including elemental analysis,FT-IR,XPS,and TG–MS.XPS characterization indicates all coked catalysts present two types of nitrogen species and the type with a higher binding energy is related with the inner part nitrogen atoms interacting with acid sites.Due to the stronger adsorption ability on acid sites for basic nitrogen compounds,the multilayer structural coke has unbalanced distribution of carbon and nitrogen atoms between the inner part and the outer edge,which strongly affects gas product formation.At the early stage of regeneration,oxidation starts from the outer edge and the product NO can be reduced to N_2 in high CO concentration.At the later stage,the inner part rich in nitrogen begins to be exposed to O_2.At this period,the formation of CO decreases due to lack of carbon atoms,which is not bene ficial to the reduction of NO.Therefore,nitrogen species in the inner part of multilayer structural coke contributes more to NO X formation.Based on the multilayer structure model of coke molecule and its oxidation behavior,a possible strategy to control NO X emission was discussed merely from concept. | Teng Li Chaohe Yang Xiaobo Chen Libo Yao Wei Liang Xuemei Ding | 2016 | Chinese Journal of Chemical Engineering2016，24，5： | 5 |
| 10 | Regulating catalyst morphology to boost the stability of Ni–Mo/Al_(2)O_(3) catalyst for ebullated-bed residue hydrotreating显示文摘Hydrotreating of vacuum residue by ebullated-bed shows tremendous significance due to more stringent environmental regulations and growing demand for lighter fuels. However, enhancing the catalyst stability still remains as a challenging task. Herein, two Ni–Mo/Al_(2)O_(3) catalysts with distinct morphologies(i.e., spherical and cylindrical) were first designed, and the morphology effect on deactivation was systematically elucidated employing multi-characterizations, such as HRTEM with EDX mapping, electron microprobe analysis, FT-IR, TGA and Raman. It is found that spherical catalyst exhibits superior hydrotreating stability over 1600 h. The carbonaceous deposits on spherical catalyst with less graphite structure are lighter, and the coke weight is also smaller. In addition, the metal deposits uniformly distribute in the spherical catalyst, which is better than the concentrated distribution near the pore mouth for the cylindrical catalyst. Furthermore, the intrinsic reason for the differences was analyzed by the bed expansion experiment. Higher bed expansion rate together with the better mass transfer ability leads to the enhanced performance. This work sheds new light on the design of more efficient industrial hydrotreating catalyst based on morphology effect. | Huihong Zhu Zhiwei Mao Bin Liu Tao Yang Xiang Feng Hao Jin Chong Peng Chaohe Yang Jifeng Wang Xiangchen Fang | 2021 | Green Energy & Environment2021，6，2： | 4 |
| 11 | 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 |
| 12 | Catalytic Cracking and PSO-RBF Neural Network Model of FCC Cycle Oil显示文摘Catalytic cracking experiments of FCC cycle oil were carried out in a fixed fluidized bed reactor.Effects of reaction conditions,such as temperature,catalyst to oil ratio and weight hourly space velocity,were investigated.Hydrocarbon composition of gasoline was analyzed by gas chromatograph.Experimental results showed that conversion of cycle oil was low on account of its poor crackability performance,and the effect of reaction conditions on gasoline yield was obvious.The paraffin content was very high in gasoline.Based on the experimental yields under different reaction conditions,a model for prediction of gasoline and diesel yields was established by radial basis function neural network(RBFNN).In the model,the product yield was viewed as function of reaction conditions.Particle swarm optimization(PSO)algorithm with global search capability was used to obtain optimal conditions for a highest yield of light oil.The results showed that the yield of gasoline and diesel predicted by RBF neural network agreed well with the experimental values.The optimized reaction conditions were obtained at a reaction temperature of around 520℃,a catalyst to oil ratio of 7.4 and a space velocity of 8 h-1.The predicted total yield of gasoline and diesel reached 42.2% under optimized conditions. | Liu Yibin Tu Yongshan Li Chunyi Yang Chaohe | 2013 | China Petroleum Processing & Petrochemical Technology2013，15，4： | 3 |
| 13 | Engineering three-layer core–shell S-1/TS-1@dendritic-SiO_(2) supported Au catalysts towards improved performance for propene epoxidation with H_(2) and O_(2)显示文摘The advocacy of green chemical industry has led to the development of highly efficient catalysts for direct gas-phase propene epoxidation with green,sustainable and simple essence.The S-1/TS-1@dendritic-SiO_(2) material with three-layer core–shell structure was developed and used as the support for Au catalysts,which showed simultaneously fantastic PO formation rate,PO selectivity and stability(over 100 h)for propene epoxidation with H_(2) and O_(2).It is found that silicalite-1(S-1)core and the middle thin layer of TS-1 offer great mass transfer ability,which could be responsible for the excellent stability.The designed dendritic SiO_(2) shell covers part of the acid sites on the external surface of TS-1,inhibiting the side reactions and improving the PO selectivity.Furthermore,three kinds of SiO_(2) shell morphologies(i.e.,dendritic,net,mesoporous shell)were designed,and relationship between shell morphology and catalytic performance was elucidated.The results in this paper harbour tremendous guiding significance for the design of highly efficient epoxidation catalysts. | Zhaoning Song Juncong Yuan Zhenping Cai Dong Lin Xiang Feng Nan Sheng Yibin Liu Xiaobo Chen Xin Jin De Chen Chaohe Yang | 2020 | Green Energy & Environment2020，5，4： | 3 |
| 14 | 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 |
| 15 | Validation of EMMS-based drag model using lattice Boltzmann simulations on GPUs显示文摘Interphase momentum transport in heterogeneous gas-solid systems with multi-scale structure is of great importance in process engineering. In this article, lattice Boltzmann simulations are performed on graphics processing units (GPUs), the computational power of which exceeds that of CPUs by more than one order of magnitude, to investigate incompressible Newtonian flow in idealized multi-scale particle-fluid systems. The structure consists of a periodic array of clusters, each constructed by a bundle of cylinders. Fixed pressure boundary condition is implemented by applying a constant body force to the flow through the medium. The bounce-back scheme is adopted on the fluid-solid interfaces, which ensures the no-slip boundary condition. The structure is studied under a wide range of particle diameters and packing fractions, and the drag coefflcient of the structure is found to be a function of voidages and fractions of the clusters, besides the traditional Reynolds number and the solid volume fractions. Parame- ters reflecting multi-scale characters are, therefore, demonstrated to be necessary in quantifying the drag force of heterogeneous gas-solid system. The numerical results in the range 0.1 ≤ Re ≤ 10 and 0 < < 0.25 are compared with Wen and Yu's correlation, Gibilaro equation, EMMS-based drag model, the Beetstra correlation and the Benyahia correlation, and good agreement is found between the simulations and the EMMS-based drag model for heterogeneous systems. | Yun Zhang Wei Ge Xiaowei Wang Chaohe Yang | 2011 | Particuology2011，9，4： | 2 |
| 16 | Techno-Economic Analysis and Life Cycle Assessment for the Typical Intermediate Crude Refining Scheme in China显示文摘The integration of refinery and petrochemical units(IRPUs)has become an inevitable choice for the sustainable development of petrochemical industry.The utilization efficiency of petroleum resources could be improved obviously through IRPUs.However,integrating economic and environmental impacts into the model of IRPUs is still a grand challenge.Herein,a model called TEA-GHG-OPWM(Techno-Economic Analysis and GreenHouse Gases Oriented Plant-Wide Model)has been established on Aspen HYSYSTM platform to calculate the energy consumption,the technoeconomic performance,and the GHG emissions for two different kinds of schemes,viz,:VRHCU(Vacuum Residue Hydrocracking Unit)and VRDS-RFCC(Vacuum Residue Desulfurization and Residue Fluid Catalytic Cracking).Furthermore,a novel processing pathway named VGOHDT-HTMP-DC(Vacuum Gas Oil Hydrotreating,Hydrogenation and TMP coupling process and Delayed Coking)has also been developed to find methods to improve the economic performance based on a ten-million-CNY output value(TMYOV)and a reduced GHG emissions.Our results demonstrate that VRHCRU could consume more energy and emit more GHG(877.11 t of CO2 eq·TMYOV^-1·h^-1)than VRDS-RFCC(817.03 t of CO2 eq·TMYOV^-1·h^-1)and VGOHDT-HTMP-DC(721.96 t of CO2 eq·TMYOV^-1·h^-1),while obtaining a higher mass yield of petrochemicals.The VGOHDT-HTMP-DC process exhibits the lowest feedstock consumption,hydrogen consumption,energy consumption,and GHG emissions,indicating that VGOHDT-HTMP-DC has both well economic and environmentally friendly performance. | Zhou Xin Yan Hao Feng Xiang Zhao Hui Liu Yibin Chen Xiaobo Yang Chaohe | 2020 | China Petroleum Processing & Petrochemical Technology2020，22，4： | 2 |

| 18 | Engineering of Co_(3O)_(4)@Ni_(2)P heterostructure as trifunctional electrocatalysts for rechargeable zinc-air battery and self-powered overall water splitting显示文摘Rational design of highly efficient,robust and nonprecious electrocatalysts for the oxygen reduction reaction(ORR),oxygen evolution reaction(OER)and hydrogen evolution reaction(HER)is highly demanded and challenging.Here,heterostructural Co_(3O)_(4)@Ni_(2)P arrays with numerous reaction sites,unique interfacial electronic structure and fast charge transfer kinetics are developed as electrocatalysts for rechargeable Zn-air batteries and overall water splitting.Both density functional theory calculation and X-ray absorption fine structure analysis manifest that the synergistic structural and abundant electronic modulations interfaces are formed,thus simultaneously promoting the electrocatalytic kinetics,activities and stabilities.Specifically,it can achieve an ultralow overpotential of 270 m V and 28 m V at 10 m A cm^(-2) for OER and HER,respectively.The water electrolyzer delivers a current density of 10 m A cm^(-2) at 1.563 V;furthermore,rechargeable Zn-air batteries triggered by this heterostructure can achieve excellent cyclic stability of 177 h(2 h per cycle)at 10 m A cm^(-2);both devices are superior to the Pt/C+Ir/C.This work not only designs an efficient trifunctional electrocatalyst but also paves an avenue to understand the heterostructure engineering for catalysts development and disclose the underlying relationship of interfacial electronic structures and catalytic properties. | Xiaolin Hu Tongxin Yang Zuguang Yang Zongyang Li Ronghua Wang Meng Li Guangsheng Huang Bin Jiang Chaohe Xu Fusheng Pan | 2022 | Journal of Materials Science & Technology2022，，20： | 1 |
| 19 | Selective propylene epoxidation in liquid phase using highly dispersed Nb catalysts incorporated in mesoporous silicates显示文摘Selective propylene epoxidation to propylene oxide(PO) with hydrogen peroxide(H_2O_2) was carried out in a catalytic semi-batch reactor.High propylene epoxidation activity(44 h^(-1)) was observed over Nb based mesoporous silicate materials Nb-TUD-1 under mild operating conditions.The physical and chemical properties of the Nb based silicates characterized using BET,FTIR,TPD,TEM and UV–Vis revealed that the site isolation and surface acidity are crucial for PO production.Catalyst synthesis methods were investigated for their effects on PO productivity,PO selectivity and H_2O_2 utilization efficiency.It is found that Nb-TUD-1 material synthesized by the sol–gel method is more active and selective than impregnated materials for liquid phase propylene epoxidation.Surface characterization confirms that thus synthesized Nb-TUD-1 catalysts have more Lewis acidity and less Bronsted acidity compared to the catalysts by impregnation. | Wenjuan Yan Yuhui Wu Xiang Feng Chaohe Yang Xin Jin Jian Shen | 2018 | Chinese Journal of Chemical Engineering2018，26，6： | 1 |
