| 1 | Identification and Characterization of Sulfur Compounds in Straight-Run Diesel Using Comprehensive Two-Dimensional GC Coupled with TOF MS显示文摘The solid-phase extraction using Pd-Al2O3 as the stationary phase was employed to pre-separate the sulfur compounds in straight-run diesel. The isolating effect was evaluated quantitatively by gas chromatography with a sulfur chemiluminescence detector to harvest a satisfactory result. The identification of the structure of sulfur compounds by comprehensive two-dimensional gas chromatography coupled with the time-of-flight mass spectrometry indicated that cyclo-sulfides, benzothiophenes, dibenzothiophenes, dihydro-benzothiophenes and tetrahydro-dibenzothiophenes were included in straightrun diesel obtained from the Arab medium crude(AM). A total of 259 individual compounds were detected and their molecular structures were identified. The analytical method was approved as an effective way to characterize the composition of sulfur compounds, which reduced the interference of other compounds, facilitated the data presentation and provided more detailed information about molecular composition of sulfur compounds. | Niu Luna Liu Zelong Tian Songbai | 2014 | China Petroleum Processing & Petrochemical Technology2014，16，3： | 10 |
| 2 | Characterization of Basic Nitrogen Aromatic Species Obtained during Fluid Catalytic Cracking by Fourier Transform Ion Cyclotron Resonance Mass Spectrometry显示文摘The basic-nitrogen aromatic compounds in feedstocks and liquid products from the micro-reactor and soluble components of coke obtained during fluid catalytic cracking (FCC) process were analyzed by the micro-electrospray ionization (ESI) 9.4T Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) with an average mass resolving power of 300 000 at a mass range of 100-1 200. The analytical results revealed that the coker gas oil (CGO) contained a higher abundance of basic-nitrogen aromatic compounds with the type of -5N to -9N compared with those in deasphalted oil (DAO) and mixed FCC feedstock. After catalytic cracking, the abundance of lowly condensed basic-nitrogen aromatic compounds was much less than those of highly condensed aromatics in the liquid products, with the carbon number mainly ranging from 6 to 25 and the average carbon number of the side-chains equating to 1-5. On the contrary, with respect to the soluble components of coke, the abundance of lowly condensed basic-nitrogen aromatic compounds was more than those of highly condensed aromatics, and the carbon number ranged from 12 to 30, which was much smaller than that of the mixed FCC feedstock but slightly larger than that of the cracked liquid products. These results have provided some fundamental information on FCC process. | Liu Yingrong Wang Wei Hu Qiuling Zhu Yuxia Deng Jinghui Tian Songbai | 2012 | China Petroleum Processing & Petrochemical Technology2012，14，2： | 8 |
| 3 | Changes of Petroleum Acid Distribution Characterized by FT-ICR MS in Heavy Acidic Crude Oil after True Boiling Point Distillation显示文摘The molecular transformations of carboxylic acids in heavy acidic SL crude before and after true boiling point distillation were examined by ultra-high resolution negative-ion electrospray ionization(ESI) Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR MS). The acid class(heteroatom number), type(z numbers) and carbon number distributions were positively characterized. It was found out that the total acid number(TAN) of SL crude decreased after true boiling point distillation, and the abundance of O2 class in mass spectra was also found to be reduced from 67.6% to 34.5% in SL TBP mixed crude as measured by MS spectra, indicating to a potential carboxylic acid decomposition. However, it was interesting that the carboxylic acids type distribution in both oils was almost the same although their relative abundance in SL TBP mixed crude turned to be much lower, suggesting that various petroleum carboxylic acid types have the similar thermal decomposition reaction behavior. Furthermore, for each O2 type of acids in SL TBP mixed crude, the abundance of carboxylic acids with carbon number higher than 35 was reduced greatly, especially for those with carbon number higher than 60, the mass peaks of which were nearly totally removed, indicating that the large carboxylic acid molecules in heavy fractions decomposed more significantly because of longer heating time during the true boiling point distillation process. As a result, the reduction of TAN may be caused by the thermal decomposition of carboxylic acids especially those with high carbon number, suggesting that quick distillation or much lower pressure is required to avoid the thermal decomposition. | Liu Yingrong Zhang Qundan Wang Wei Liu Zelong Zhu Xinyi Tian Songbai | 2014 | China Petroleum Processing & Petrochemical Technology2014，16，1： | 8 |
| 4 | Corresponding Factors Influencing Crude Oils Assay Using Low-field Nuclear Magnetic Resonance显示文摘In this study, the main factors influencing the measurements by means of the off-line low-field 1H NMR in the lab were discussed base on a robust calibration model established by the PLS algorithm using 255 crude oil samples. The preheating temperature had a great influence on the viscosity of oil samples and the resolution of spectral analysis. The repeatability of spectral measurements was impacted by the metal and wax content of the oil samples. For the case of high wax content oils, the wax species began to crystallize in the course of determination that could affect the repeatability of spectral measurements. These factors have evidenced why the preheating devices and filter unit are necessary when low field NMR system is used in the online analysis process. The investigation is very important for the on-line application of the low field NMR. | Feng Yunxia Chu Xiaoli Xu Yupeng Tian Songbai | 2014 | China Petroleum Processing & Petrochemical Technology2014，16，2： | 4 |
| 5 | Molecular Characterization of Hydrotreated Atmospheric Residue Derived from Arabian Heavy Crude by GC FI/FD TOF MS and APPI FT-ICR MS显示文摘High resolution mass spectrometry in combination with distillation and SARA fractionation provides us an opportunity for in-depth understanding about the hydrotreating process at the molecular level. In this study, the atmospheric residue derived from Arabian heavy crude and its hydrotreated products were initially subjected to distillation and SARA fractionation. The saturates were characterized by GC FI/FD TOF MS. The aromatics and resins were characterized by APPI FT-ICR MS. Compositional changes of different compounds (paraffins, naphthenes, aromatic hydrocarbons, and heteroatomic compounds) contained in different distillates (vacuum gas oil, vacuum residue) were obtained. More detailed knowledge about the hydrotreating process was achieved. | Diao Rui Wang Wei Wang Naixin Liu Zelong Dai Lishun Tian Songbai | 2012 | China Petroleum Processing & Petrochemical Technology2012，14，4： | 4 |
| 6 | A Method for Crude Oil Selection and Blending Optimization Based on Improved Cuckoo Search Algorithm显示文摘Refineries often need to find similar crude oil to replace the scarce crude oil for stabilizing the feedstock property. We introduced the method for calculation of crude blended properties firstly, and then created a crude oil selection and blending optimization model based on the data of crude oil property. The model is a mixed-integer nonlinear programming(MINLP) with constraints, and the target is to maximize the similarity between the blended crude oil and the objective crude oil. Furthermore, the model takes into account the selection of crude oils and their blending ratios simultaneously, and transforms the problem of looking for similar crude oil into the crude oil selection and blending optimization problem. We applied the Improved Cuckoo Search(ICS) algorithm to solving the model. Through the simulations, ICS was compared with the genetic algorithm, the particle swarm optimization algorithm and the CPLEX solver. The results show that ICS has very good optimization efficiency. The blending solution can provide a reference for refineries to find the similar crude oil. And the method proposed can also give some references to selection and blending optimization of other materials. | Yang Huihua Ma Wei Zhang Xiaofeng Li Hu Tian Songbai | 2014 | China Petroleum Processing & Petrochemical Technology2014，16，4： | 4 |

| 8 | Quantitative Analysis Using Fourier Transform Ion Cyclotron Resonance Mass Spectrometry and Correlation between Mass Spectrometry Data and Sulfur Content of Crude Oils显示文摘Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR MS) has become a powerful tool for analyzing the detailed composition of petroleum samples. However, the correlation between the numerous peaks obtained by FT-ICR MS and bulk properties of petroleum samples is still a challenge. In this study, the internal standard method was applied for the quantitative analysis of four straight-run vacuum gas oils(VGO) by atmospheric pressure photoionization(APPI) FT-ICR MS. The heteroatom class distribution of these VGO samples turned to be different when the concentration changed. Linear relationship between the normalized abundance and the concentration of VGO samples was identified for the total aromatic compounds, aromatic hydrocarbons, S1 and N1 species. The differences of the response factors were also discussed. The sulfur contents of a series of crude oils were proved to be linear with the FT-ICR MS data calibrated by the response factor of S1 species. This study demonstrated the feasibility of the internal standard method in quantitative analysis with APPI FT-ICR MS, and the bulk properties of petroleum samples could be correlated directly with the FT-ICR MS data. | Wang Wei Liu Yingrong Liu Zelong Tian Songbai | 2015 | China Petroleum Processing & Petrochemical Technology2015，17，4： | 3 |
| 9 | Review and Comprehensive Analysis of Deaggregation and Separation Methods for Asphaltene Aggregates显示文摘Asphaltenes generally exist in the form of molecular aggregates in crude oil or in petroleum residues,and asphaltene aggregates can usually cause serious problems to oil exploitation,transportation,and processing.Achieving deaggregation and separation of asphaltene aggregates is a premise and basis for molecular characterization and processing of heavy oils.Aiming at the intermolecular interactions in asphaltene molecular aggregates,it has proposed and summarized that aspahltene aggregates can be subject to deaggregation by means of five approaches,including solvent diluting,removing active sites,moderate heating,ultrasonication and on-line molecular collision.Moreover,asphaltenes can be further separated to narrow fractions for molecular-level research based on polarity difference,molecular size difference,acid-base properties,and reactivity difference. | Cai Xinheng Long Jun Dong Ming Wang Wei Hou Huandi Tian Songbai | 2020 | China Petroleum Processing & Petrochemical Technology2020，22，2： | 3 |
| 10 | Linkage of Aromatic Ring Structures in Saturates, Aromatics, Resins and Asphaltenes Fractions of Vacuum Residues Determined by Collision-Induced Dissociation Technology显示文摘The linkage of aromatic ring structures in vacuum residues was important for the refining process. The Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR MS) combined with collision-induced dissociation(CID) is a powerful method to characterize the molecular structure of petroleum fractions. In this work, model compounds with different aromatic ring structures were measured by CID FT-ICR MS. The cracking of the parent ions and the generated fragment ions were able to distinguish different linkage of the model compounds. Then, vacuum residues were separated into saturates, aromatics, resins and asphaltenes fractions(SARA), and each fraction was characterized by CID technology. According to the experimental results, the aromatic rings in saturates and aromatics fractions were mainly of the island-type structures, while the aromatic rings in resins and asphaltenes fractions had a significant amount of archipelago-type structures. | Wang Wei Liu Yingrong Liu Zelong Hou Huandi Tian Songbai | 2016 | China Petroleum Processing & Petrochemical Technology2016，18，1： | 3 |
| 11 | Comparative transcriptome analysis identifies differentially expressed genes between normal and late-blooming Siberian apricot显示文摘Blooming date is an important trait in fruit tree species.Although several quantitative trait loci confirming blooming date were identified in Prunus spp.,the molecular mechanism underlying it remains unclear.Arising from this,the transcriptomes of normal blooming and lateblooming Siberian apricot(P.sibirica L.)flower buds were analyzed using RNA-seq technology.A total of 68,855 unigenes were de novo assembled,among which 1204 were differentially expressed between normal and late blooming.Gene ontology enrichment analysis revealed that biological processes were enriched with metabolic processes.The catalytic-related gene transcripts between the two types of blooming were significantly changed in the molecular function.Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that 156 genes were successfully annotated and 75 pathways enriched.Genes for gibberellin biosynthesis were up-regulated in normal blooming,whereas abscisic acid degradation-related genes were also up-regulated in normal blooming.Moreover,circadian rhythms related genes including EARLY FLOWERING 4,LATE ELONGATED HYPOCOTYL and CIRCANDIAN CLOCK ASSOCIATED1 were all up-regulated in normal blooming,indicating that circadian rhythms have a very important role in controlling blooming date.Furthermore,zinc finger protein CONSTANS-LIKE 12 was blasted onto the quantitative trait loci region on linkage group 4 in peach.However,changes in the abundance of key flowering genes such as SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1,FLOWERING LOCU T,LEAFY and FLOWERING LOCUS C were not significantly different,indicating that further investigation should explore the function of these genes on blooming date.The outcomes of this study will provide a valuable platform for further research on the molecular mechanism of blooming date in Prunus. | Zhe Wang Shuang Song Songbai Sheng Ju Tian Rongling Wu Xiaoming Pang | 2019 | Journal of Forestry Research2019，30，6： | 3 |
| 12 | Research on Determination of Nitrogen Content in Petroleum Using Mid-infrared Spectroscopy显示文摘Nitrogen content is an important parameter for petroleum refining processes. The combined use of mid-infrared attenuated total reflection spectroscopy and multivariate calibration allows accurate determination of nitrogen content in petroleum and its products. The calibration models of nitrogen content in crude oils have been established by partial least squares (PLS) method. The results predicted by this method were very close to those determined by standard methods. Compared with standard methods, this method is provided with advantages such as high-speed, simplicity and good-repeat- ability without any needs for pretreatment. | Li Jingyan Chu Xiaoli Tian Songbai Lu Wanzhen (SINOPEC Research Institute of Petroleum Processing, Beijing 100083) | 2011 | China Petroleum Processing & Petrochemical Technology2011，13，4： | 2 |
| 13 | Direct Fingerprinting Polycyclic Aromatic Hydrocarbons in Heavy Oils by PY-GC/MS and Its Application to Hydrotreating Processes显示文摘An efficient analytical method combining pyrolysis and capillary GC/MS has been developed for determination and quantitation of targeted polycyclic aromatic hydrocarbons.The limit of detection ranged from 0.29 μg/g to 43.46 μg/g,and repeatability values were between 0.1% and 8.2% for blank spiked samples and between 0.1 % and 9.8% for real samples of heavy oils.Through application of the proposed method in hydrotreating processes,it has been found out that heavy oils before and after the specified hydroprocessing treatment exhibited a diverse PAHs distribution which might be determined by the discrepancy in their intrinsic contents and hydrogenation reactivity.Furthermore,the hydrogenation reactivity of different polycyclic aromatic hydrocarbons was further investigated and discovered to be more interrelated to molecular structure and rings alignment or conjugation mode. | Cai Xinheng Liu Yingrong Tian Songbai Zhou Jian Liu Zelong | 2012 | China Petroleum Processing & Petrochemical Technology2012，14，1： | 2 |

| 17 | Structural Characterization of Petroleum Molecules by CID FT-ICR MS with Narrow Isolation Window显示文摘High resolution tandem mass spectrometry has been applied to obtain the structure information of petroleum samples. Here, we report a method for structural characterization of crude oil molecules by the collision-induced dissociation(CID) technology coupled with the high-field Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR MS). The ion isolation window was narrowed down to 1 Da to distinguish the complex homologues contained in petroleum. Aromatic model compounds and crude oil samples were measured by CID FT-ICR MS at different collision energy levels. The fragmentation of model compounds with alkyl side-chains was found to be related to the size of the aromatic rings. The fragmentation of model compounds with archipelago structures depended on the length of the bridge alkylene chain. The prevalent reaction pathway of model compounds with naphthenic rings was mainly determined by the position of naphthenic rings in the molecules. On the basis of the fragmentation pathways, the structure differences of two crude oils were recognized as different content of naphthenic rings by CID technology with 1 Da isolation window. The NMR analysis was also applied to confirm the CID results. This study exhibits the great potential of CID FT-ICR MS with narrow isolation window in the structural characterization of crude oil molecules. | Liu Ling Zhang Yiwei Zhang Zhihua Hou Huandi Zhang Qundan Tian Songbai Wang Wei | 2018 | China Petroleum Processing & Petrochemical Technology2018，20，3： | 1 |

| 19 | Influence of Different Hydrocarbon Molecules on Physical Properties of Mineral Base Oils显示文摘Different kinds of base oils with different viscosity were analyzed in this paper, including eight mineral base oils, alkylnaphthalene and three synthetic PAO oils. The influence of different hydrocarbon molecules on physical properties of mineral base oils was investigated, such as density(d), kinematic viscosity(KV), viscosity index(VI), etc. Possible reasons for some inconsistent phenomena in data processing were also theoretically analyzed in detail. The refractive indexes(RI), d and molecular weight(M) decrease linearly with the increase of paraffinic content other than KV, which declines exponentially. There are no clear relationships between physical properties of base oils and naphthenic content while polycyclic alkanes show a strong correlation with M and KV. The influence of aromatics on physical properties of base oils is just the opposite of paraffin's. VI of the base oils with low aromatics content increases linearly as their paraffinic contents rise when their carbon numbers are approximately equal. However, base oils with high aromatics content follow an utterly different rule, in which VI declines dramatically linearly with the increase in polycyclic aromatic content, which is the essential reason why naphthenic base oils all have terrible viscosity-temperature characteristics while paraffinic base oils usually do not. | Wang Weijun Long Jun He Yifeng Sun Hongwei Tian Songbai Zheng Hui | 2017 | China Petroleum Processing & Petrochemical Technology2017，19，1： | 1 |
