| 1 | Meditation promotes insightful problem-solving by keeping people in amindful and alert conscious state显示文摘Although previous studies have shown that sleep can inspire insight,it is still unclear whether meditation can promote insight.Meditation differs from other types of passive rest such as relaxation and sleep because it requires full consciousness andmindfulness of targets such as one's breathing.Forty-eight university students without meditation experience were recruited to learn a simple meditation technique.They were given a list of 10 insight problems to solve (the pre-test session).In this study,we focused on the unsolved problems and examined if they could be successfully solved after a 20min rest interval with or without meditation.Results showed that relative to the control group that listened to Chinese or English words and made a language judgment,the groups who learned meditation successfully solved significantly more failed problems from the pre-test session,providing direct evidence for the role of meditation in promoting insight.Further analysis showed that maintaining amindful and alert state during meditation (raising a hand to report every 10 deep breaths compared to every 100 deep breaths) resulted in more insight regarding the failed items from the pre-test session.This implies that it was watchfulness in meditation,rather than relaxation,that actually contributed to insight.Consistently,in the meditation session or control task,the percentage of alpha waves—a brain index of mental relaxation—was negatively correlated with insight.These results suggest a meditation-based insight-promoting mechanism different from that involved in passive rest such as relaxation and sleep. | REN Jun HUANG ZhiHui LUO Jing WEI GaoXia YING XiaoPing DING ZhiGuang WU YiBin LUO Fei | 2011 | Science China(Life Sciences)2011，54，10： | 11 |
| 2 | The Function of β Zeolite for Enhancing the Propylene Yield in FCC Process显示文摘The ultra-stable Y zeolite, modified β zeolite, and modified ZSM-5 zeolite were characterized by NH3-TPD analysis. The results showed that the acidic substance of modified β zeolite is between that of the Y zeolite and the ZSM-5 zeolite. These three kinds of zeolites were evaluated by using hexane, decane and light diesel serving as feedstocks with different molecular size. The results showed that these three kinds of zeolites had different cracking capability and product distribution obtained for cracking hydrocarbons with different molecular sizes as a result of the difference in pore structure and acidic substances. The modified β zeolite can produce much more C_5~= —C_8~= olefins, which are excellent precursors of propylene. Then the mixed samples of these three kinds of zeolites were tested in the VGO microreactor unit, and the test results showed that the modified β zeolite played a ‘relay role' between the ultra-stable Y zeolite and the modified ZSM-5 zeolite, so that the composite made of the ultra-stable Y zeolite, the modified β zeolite, and the modified ZSM-5 zeolite showed a highest propylene yield and selectivity. | Ouyang Ying Luo Yibin Shu Xingtian | 2017 | China Petroleum Processing & Petrochemical Technology2017，19，4： | 4 |

| 4 | Enhancing hydrothermal stability of framework Al in ZSM-5:From the view on the transformation between P and Al species by solid-state NMR spectroscopy显示文摘HZSM-5,with good surface acidity and shape selectivity,was reported as hydrocarbon cracking catalyst for multiple decades,however the hydrothermal stability,especially dealumination of tetrahedrally coordinated framework aluminum(TFAl),has been proved extensively as one of the major challenges during reactionregeneration process.Phosphorus was proposed to stabilize TFAl and indeed it enhanced the hydrothermal stability.Unfortunately,most of the phosphorus species would remain outside of the zeolite pore,mainly as polyphosphate species,and block the micropore severely,with only a limited portion introduced into the channel being able to interact with TFAl.Enlarging the pore size by alkali treatment(desilication)is one of the most convinced methods,but the details about specific P species during alkali treatment and its transformation upon hydrothermal activation is not acquired,thus the mechanism has not been fully understood.Herein,the P-containing species and its transformation during direct P modification and acid/alkali treatment followed by Pmodification have been studied,and the mechanism on the interaction between P and Al species has been investigated,using several analytical methods,especially Solid-state nuclear magnetic resonance(SSNMR)spectroscopy.It was found that the combination of desilication and subsequent phosphorus modification can enhance the activity of the ZSM-5 for the cracking of ethylcyclohexane,due to the better hydrothermal stabilization of acid sites by the enhanced interaction between phosphorus and TFAl,resulting from the improved accessibility of TFAl because of the successful generation of mesoporosity.Whereas the acid treatment followed by phosphorus modification,with declined retention of crystallinity and P/Al ratio,monoclinic/orthorhombic transition during steam activation,and the failed generation of mesopores,would cause obvious aggregation of the phosphorus species and could not improve the hydrothermal stability of the ZSM-5 effectively,and the direct phosphatation turned out much worse.Finally,a specific index that the intensity of the signal at 39 in 27Al MAS NMR spectra before steam activation was proposed as the indicator for determining the efficiency of phosphorus modification.And the proposed mechanism on the interaction between phosphorus and TFAl during the phosphorus modification could also be applicable in other zeolites. | Lei Han Ying Ouyang Enhui Xing Yibin Luo Zhijian Da | 2020 | Chinese Journal of Chemical Engineering2020，28，12： | 3 |
| 5 | Investigation on Organic Solvent Free Toluene Oxidative Bromination Reaction Catalyzed by HTS Zeolite显示文摘The toluene oxidative bromination reaction catalyzed by hollow titanium silicalite(HTS)zeolite in aqueous medium was investigated by employing H2O2 and HBr under mild conditions without the need for organic solvent.A high toluene conversion(90.7%)and high selectivity of mono-bromotoluene(99.0%)was achieved under the optimal reaction conditions.The UV-Raman spectroscopy was applied for the mechanism study and the result reveals that HTS is efficient for catalyzing the oxidation reaction of HBr with H2O2 to produce abundant active bromine species,which can further facilitate the toluene electrophilic bromination reaction.A two-step toluene bromination reaction mechanism involving the HTS catalyzed active bromine species“generation-conversion-utilization”process is proposed based on the UV-Raman spectroscopy analysis. | Peng Xinxin Xia Changjiu Lin Min Zhu Bin Luo Yibin Shu Xingtian | 2020 | China Petroleum Processing & Petrochemical Technology2020，22，4： | 2 |
| 6 | Investigation of the Ion-Exchange Behavior of Zeolite Y in the Presence of Resin显示文摘Ion-exchange process of zeolite Y using ammonium-type resin as an exchange reagent was successfully carried out. The effect of temperature, space velocity and ion concentration on the breakthrough curves was carefully investigated. At the first exchange section, the maximum proportion of qualified zeolites(QR) was obtained at a temperature of 70 ℃, a weight hourly space velocity of 0.61 h-1, and an ion concentration of 197 mg/L. The minimum length of mass-transfer zone(MTZ) of the resin bed was achieved at a temperature of 70 ℃, a space velocity of 0.61 h-1, and an ion concentration of 423 mg/L. At the second exchange section, the length of MTZ of the resin bed was significantly increased, and the exchange of Na+ ions contained in zeolite Y was more difficult than that achieved at the first exchange section. In both the first and the second exchange sections, the zeolite Y subjected to ion exchange with the resin maintained the similar physical and chemical properties as compared to those exchanged by the conventional approaches, but the zeolite Y, which was obtained after ion exchange, contained a significantly lower content of Na2 O. | Zhang Yi Zheng Jinyu Liu Zhongqing Gao Xiuzhi Luo Yibin Zong Baoning | 2015 | China Petroleum Processing & Petrochemical Technology2015，17，2： | 2 |
| 7 | Effects of Metal Oxide in ZSM-5 Zeolite on Its Catalytic Performance in FCC Process显示文摘Effects of metal oxide in ZSM-5 zeolite on its catalytic performance in fluid catalytic cracking reaction were studied via characterization by XRD and FT-IR spectroscopy using pyridine and collidine as molecular probes,and the modified ZSM-5 zeolite was evaluated in a micro reactor using standard light diesel fraction as the feedstock.Test results indicate that the metal species introduced into the ZSM-5 zeolite had led to the formation of Lewis acid centers.When the modified ZSM-5 zeolite with the metal species on its surface was used as the catalyst in FCC reaction,both the propylene yield and the propylene concentration in the liquefied petroleum gas increased,but in the meantime,more hydrogen and coke were formed at high conversion rate under the joint action of nonselective cracking of Lewis acid centers and dehydrogenation at metal centers on its outside surface. | Qin Jinlai Ouyang Ying Li Minggang Luo Yibin Shu Xingtian(SINOPEC Research Institute of Petroleum Processing,Beijing 100083) | 2011 | China Petroleum Processing & Petrochemical Technology2011，13，2： | 2 |
| 8 | Synthesis of Nanosized SSZ-13 Zeolite and Performance of Its Mixed Matrix Membrane for CO2/CH4 Separation显示文摘Nanosized SSZ-13 zeolite was synthesized by traditional hydrothermal method using N,N,N-trimethyl-1-adamantanaminium hydroxide as the structure-directing agent (SDA). The influence of different preparative conditions of nanosized SSZ-13 was investigated systematically. The synthetic zeolites were characterized by X-ray powder diffraction (XRD), nitrogen physisorption, and scanning electron microscopy (SEM). By means of the self-assembled method, the thin SSZ-13/polyvinyl alcohol nanocomposite membranes were obtained by incorporating the nanosized SSZ-13 zeolite into the polymeric precursor (polyvinyl alcohol (PVA)). The permeation properties of pure CO2 and CH4 through the mixed matrix membranes (MMMs) were measured. The results showed that the highly crystalline SSZ-13 zeolite in a dispersed nanocrystal form with a controllable particle size of 100 nm could be hydrothermally synthesized by optimizing the synthetic parameters and the selectivity of CO2/CH4 of the MMMs could reach a value of 40 by changing the amount of nanosized SSZ-13 zeolite. | Liu Jianqiang Luo Yibin Li Minggang Shu Xingtian | 2019 | China Petroleum Processing & Petrochemical Technology2019，21，2： | 2 |
| 9 | Regulating Charge and Exciton Distribution in High-Performance Hybrid White Organic Light-Emitting Diodes with n-Type Interlayer Switch显示文摘The interlayer(IL) plays a vital role in hybrid white organic light-emitting diodes(WOLEDs); however,only a negligible amount of attention has been given to n-type ILs. Herein, the n-type IL, for the first time,has been demonstrated to achieve a high efficiency, high color rendering index(CRI), and low voltage trade-off.The device exhibits a maximum total efficiency of 41.5 lm W^(-1), the highest among hybrid WOLEDs with n-type ILs. In addition, high CRIs(80–88) at practical luminances(C1000 cd m^(-2)) have been obtained, satisfying the demand for indoor lighting. Remarkably, a CRI of 88 is the highest among hybrid WOLEDs. Moreover, the device exhibits low voltages, with a turn-on voltage of only 2.5 V([1 cd m^(-2)), which is the lowest among hybrid WOLEDs. The intrinsic working mechanism of the device has also been explored; in particular, the role of n-type ILs in regulating the distribution of charges and excitons has been unveiled. The findings demonstrate that the introduction of n-type ILs is effective in developing high-performance hybrid WOLEDs. | Dongxiang Luo Yanfeng Yang Ye Xiao Yu Zhao Yibin Yang Baiquan Liu | 2017 | Nano-Micro Letters2017，9，4： | 1 |
| 10 | Research on Bipolar Membrane Electrodialysis for Ion Exchange of Molecular Sieves显示文摘In view of the problems associated with large amount of discharged wastewater and serious pollution in the existing technology for removing sodium species from molecular sieves,this research work introduces the bipolar membrane electrodialysis into the process of removing sodium species from molecular sieves,and proposes a novel method of cleanly removing sodium from molecular sieves.The results show that the technology for removing sodium ions from the molecular sieves with an indirect electrodialysis process is feasible,and can recover Na OH solution.The bipolar membrane electrodialysis is especially suitable for treating the USY,ZSM-5 and Beta molecular sieves with high acid-resistance,and the physicochemical properties and catalytic performance of the prepared molecular sieves are roughly equivalent to those of the ammonium ion-exchange method.In comparison with the ammonium ion-exchange method,the process is clean and environmentally friendly,which consumes less water,and does not discharge wastewater to exhibit a rosy prospect of industrial application. | Chen Beiyan Liu Zhongqing Zhou Lina Luo Yibin Shu Xingtian | 2018 | China Petroleum Processing & Petrochemical Technology2018，20，2： | 1 |

| 13 | Rational construction of multiple hollow silicalite-1 zeolite with enhanced quasi acidity for robust vapor-phase Beckmann rearrangement显示文摘Developing efficient and stable zeolites for vapor-phase Beckmann rearrangement of cyclohexanone oxime is still a great challenge to realizeε-caprolactam(CPL)green production.In this work,the hierarchical porous silicalite-1 zeolites with multiple hollow structure(S-1-M)are explored by in-situ desilication−recrystallization post-treatment of spongy highway-like zeolites(S-1-S),which are synthesized through silanization synthesis of conventional bulky silicalite-1(S-1).Compared to S-1,S-1-M achieves superior catalytic performance,with improving the CPL selectivity from 85.7%to 94.1%and prolonging the catalyst lifetime from 74 to 126 h at a weight hourly space velocity(WHSV)of 6 h^(−1).Comprehensive physiochemical studies demonstrate that the highly dispersed intracrystalline cavities within S-1-M endow greater mass diffusion and better quasi acidity inducing by the enhanced H-bonds among abundant H-bonded silanols,which is cooperatively responsible for its superior catalytic performance. | Peng Zhang Xianfeng Yi Changjiu Xia Xinxin Peng Shuai Zhang Chengxiang Li Anmin Zheng Xiaoxin Zhang Yibin Luo Lifeng Cui Fuhong Yu Xingtian Shu | 2023 | Nano Research2023，16，5： | 1 |
| 14 | Insights into the Reaction Network and Mechanism of Green Aerobic Oxidative Esterification of Methacrolein over Different Heterogeneous Catalysts显示文摘The oxidative esterification of methacrolein(MAL)is an important way to prepare high-valued methyl methacrylate(MMA),but this process is ultra-complex due to the high reactivity of both C=O and C=C bonds in MAL molecule.In order to further improve MMA selectivity,the reaction network and relevant mechanisms have been proposed and profoundly investigated in this paper.Five kinds of fundamental reactions are involved in this process,including(a)the acetal reaction;(b)the aerobic oxidation of hemiacetal;(c)the alkoxylation of C=C double bond;(d)the Diels-Alder reaction;and(e)the hydrogenation reaction of unsaturated double bond.Among them,the Diels-Alder reaction of MAL is non-catalyzed,and the Brönsted acid sites or the Lewis acid sites favor promoting acetal reaction of MAL with methanol,while the alkoxylation of C=C bond with methanol is enhanced under alkaline condition.In particular,by employing the Pd-based catalysts,hydrogenation products are formed in alkaline methanol solution,hence with lower than those obtained by the Au-based catalysts.Notably,it is necessary to match the hemiacetal fromation and aerobic oxidation of hemiacetal,which is relevant with the amount and strength of acid and redox sites.Consequently,this work can provide a good guidance for the further design of both catalysts and processes in future. | Li Chenhao Xia Changjiu Liu Yujia Huang Kaimeng Peng Xinxin Liu Jinsheng Lin Min Zhu Bin Luo Yibin Shu Xingtian | 2021 | China Petroleum Processing & Petrochemical Technology2021，23，3： | 1 |
| 15 | Research Progress in Refining Process for Production of Caprolactam by Beckman Rearrangement Reaction显示文摘Caprolactam, which is mainly produced via the Beckmann rearrangement reaction, is an important chemical material. The strict specifications of caprolactam products make the refining process of caprolactam extremely important. According to the different rearrangement process, the refining process of caprolactam is also different. The main refining sequence of liquid phase rearrangement products includes extraction, ion exchange, hydrogenation, and distillation. The refining process of gas phase rearrangement products is conducted mainly through distillation, crystallization, and hydrogenation. In this paper, the research progress of caprolactam refining technology will be summarized according to different rearrangement reaction processes, which will provide a reference for the selection of appropriate caprolactam refining process. | Wang Hao Zhang Dejiang Fan Yingqi Xie Li Luo Yibin Zong Baoning | 2019 | China Petroleum Processing & Petrochemical Technology2019，21，2： | 1 |
| 16 | Catalyst for Increasing Ethylene and Propylene Production and Its Industrial Application in a Catalytic Pyrolysis Unit显示文摘Light olefins,particularly ethylene and propylene,are the most important building blocks for the petrochemical industry,and demand for their production has been increasing.The catalytic pyrolysis process(CPP)and the corresponding catalyst,developed by SINOPEC Research Institute of Petroleum Processing Co.,Ltd.,are designed to maximize the light olefin yield from catalytic cracking of heavy feedstocks.However,owing to the continuing degradation of feedstocks,the original catalyst can no longer maintain its activity.Herein,we describe the rational design of the new catalyst,Epylene,from a new metal-modified hierarchical ZSM-5 zeolite and matrix.Epylene was tested in the CPP unit of Shaanxi Yanchang Coal Yulin Energy and Chemical Company.A test run and base run were conducted to demonstrate the better performance of Epylene compared with the original catalyst.The properties of the feedstocks and the operating conditions in both runs were similar.The light olefin yield was increased from 33.95%to 36.50%and the coke yield was only 9.58%in the test run,which was lower than that in the base run. | Sha Yuchen Wang Peng Ouyang Ying Zhu Genquan Lu Lijun Song Haitao Lin Wei Luo Yibin | 2023 | China Petroleum Processing & Petrochemical Technology2023，25，2： | 1 |

| 18 | A privacy-enhancing scheme against contextual knowledge-based attacks in location-based services显示文摘1 Introduction and main contributions Location-based services are springing up around us,while leakages of users'privacy are inevitable during services.Even worse,adversaries may analyze intercepted service data,and extract more privacy like health and property.Therefore,privacy preservation is an indispensable guarantee on LBS security.Among the previous approaches to privacy preservation,k-anonymity-based ones have drawn much research attention[1-3].However,some privacy concern will be aroused if these schemes are adopted directly.For instance,Ut issues a query'Find the nearest hotel around me'in such an area as Fig.1(privacy profile k=4).DLS algorithm[2]constructs anonymity set A because these four cells have similar probabilities of being queried in the past.However,experienced adversaries can exclude some cells if they have learned rich contextual knowledge(side information)from historical data,such as features of each cell and LBS users. | Jiaxun HUA Yu LIU Yibin SHEN Xiuxia TIAN Yifeng LUO Cheqing JIN | 2020 | Frontiers of Computer Science2020，14，3： | 0 |
| 19 | Pore plugging effects on the performance of ZSM-5 catalyst in MTP reaction using a discrete model显示文摘Coke is an important medium for connecting reaction and regeneration of the methanol to propylene process on the ZSM5 catalyst.Coke grows in the meso and macro pores,it gradually worsens the diffusion inside the catalyst particle.Furthermore,pore plugging is inevitable which causes the deactivation of ZSM5 catalyst.However,current continuum model cannot reflect the changes in pore structure with clear physical concepts.A discrete model that is verified by the carbon deposition experiments is introduced to indicate the behavior of pore plugging effects.Results show that the pore plugging has a significant effect on the performance of the catalyst.The time varying profile of effectiveness factor is obtained,indicating a regular reduction with the increase of the pore plugging effect.Spatial distributions of pore size that would significantly enhance the plugging effect are also identified. | Yudong Shen Hao Liang Zuwei Liao Binbo Jiang Jingdai Wang Yongrong Yang Minggang Li Yibin Luo Xingtian Shu | 2021 | Chinese Journal of Chemical Engineering2021，34，4： | 0 |
