Molecular Simulation Study on Intrinsic Order of Interaction between Single Slab of Active Phase and Al-Si Support in HDS Catalysts

引用

china petroleum Processing & Petrochemical Technology 2011年第2期13卷 29-35页

作者： Li Haoguang Nie Hong Zhou Han Li Dadong(sinopec research institute of petroleum Processing,beijing 100083) sinopec Research Institute of Petroleum Processing Beijing 100083 China

Molecular mechanics and quantum mechanics simulations, as molecular simulation methods, were performed to investigate the effects of different surfaces, the promoter Co/Ni, the active phase of MoS2 or WS2, the content of Si and other factors on the order of interaction between the MoS2 （WS2） single slab and the support surface. The influence of Si content was studied by molecular mechanics, and an advantageous Si content was found. Various surfaces, promoters and active phases also played an important role in the interaction between the support surfaces and active phases, and some significant trends were found out. Quantum mechanics simulation was performed to study the possible effect of electrostatic interaction between the support and the active phase, upon which the calculations suggested that the existence of a favorable Si content was possible. The electronic effects of Co/Ni promoter and the intensity of Co/Mo/Ni/W/Li/AI/Si species bonded to the alumina support were also investigated by quantum mechanics, and it was found that the different electronic effects of Co and Ni might bring forth some obvious influences on the interaction between the support and the active phase. And the results of comparing the intensity of Co/Mo/Ni/W/Li/AI/Si species bonded to the support can also explain the different interaction intensity in various catalyst systems.

FILICOPSIDA is a predominant group of the Early Cretaceous floras of Northeast china, whichapproximates 100 species and accounts for more than one third of the floras. The majority ofthis group are of great importance and significance in stratigraphy. The previous studies ofthese ferns are mainly morphological, with only a few concerning the in situ spores andsporangia. In recent years. the authors have carried out a research project on the in situreproductive organs of the Early Cretaceous ferns from/ basins of Inner Mongolia, Liaoning,Jilin and Heilongjiang of Northeast china. The study focuses on 35 species of 17 genera be-longing to 10 families. The present note briefly introduces the results of this study by listingsome representative species.

Effects of Vanadium Oxidation Number on Light Olefins Selectivity of FCC Catalyst

引用

china petroleum Processing & Petrochemical Technology 2011年第2期13卷 1-8页

作者： Liu Yujian Long Jun Tian Huiping Zhou Han(research institute of petroleum Processing,sinopec,beijing 100083) research institute of petroleum Processing SINOPEC Beijing 100083 China

Effects of vanadium on light olefins selectivity of FCC catalysts were investigated with vanadium having different oxidation numbers （hereinafter abbreviated as Oxnum）. Molecular modeling studies showed that vanadium with low Oxnum could affect the chemical conversion of large-size hydrocarbon molecules. However, the vanadium deposited on equilibrium catalyst bad high Oxnum because of the oxidation reaction taking place in the regenerator, so an activation method to reduce vanadium Oxnum named ＂selective activation＂ was introduced. It was proved by means of Electron Paramagnetic Resonance （EPR） and Temperature-Programmed Reduction （TPR） methods that the vanadium Oxnum was decreased, when the catalyst was activated. The molecular modeling studies are consistent well with the lab evaluation results. The light olefins selectivity of activated equilibrium catalysts was better than that achieved by the inactivated catalysts. Similar results were observed with the lab vanadium-contaminated catalyst. The light olefins selectivity of the catalyst was optimized when the vanadium Oxnum was close to 2 （VO）.

research on Determination of Nitrogen Content in petroleum Using Mid-infrared Spectroscopy

引用

china petroleum Processing & Petrochemical Technology 2011年第4期13卷 1-7页

作者： Li Jingyan Chu Xiaoli Tian Songbai Lu Wanzhen (sinopec research institute of petroleum Processing, beijing 100083) sinopec research institute of petroleum Processing Beijing 100083 China

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.

作者： Sun Xin Long Jun Xu Benjing Xie Chaogang (research institute of petroleum Processing, sinopec, beijing 100083) research institute of petroleum Processing SINOPEC Beijing 100083 China

Oxidative desulfurization was performed on Na2WO4 catalyst in the presence of hydrogen peroxide and acetic acid under mild reaction conditions （atmospheric pressure and temperature range of 293--343 K）. Different organic compounds including benzothiophene （BT）, dibenzothiophene （DBT）, 4, 6-dimethyl dibenzothiophene （4, 6-DMDBT） were used to investigate the reactivity of this catalyst, and the effect of various parameters, such as temperature, solvents and the amount of oxidant reagent used in oxidative desulfurization reaction, was also examined. The results showed that the Na2WO4- H202 system was very effective for oxidative desulfurization, and the oxidation of BT, DBT and 4, 6-DMDBT was influenced by different parameters.

作者： Liu Jun Long Jun He Zhenfu Dai Zhenyu (research institute of petroleum Processing,sinopec,beijing 100083) research institute of petroleum Processing SINOPEC Beijing 100083 China

The C--C bond dissociation energy （BDE） is a very important data in research of hydrocarbon cracking reactions, because it reflects the difficulty level of chemical reactions. But it is very difficult to obtain the C--C bond dissociation energy （BDE） by experiments, so using quantum chemistry calculation such as density functional theory （DFT） to study the C--C bond dissociation energy is a very useful means. The impact of acceptor substituents and donor substituents on the C--C bond length distribution was studied.

Inst. Petrol. Explor./Devmt. Beijing 100083 China

In this paper, a direct method, unsymmetric-pattern multifrontal factorization, for a large sparse system of linear equations is applied in the compositional reservoir model. The good performances of this approach are shown by solving the Poisson equation. And then the numerical module is embedded in the compositional model for simulating X15(3) gas condensate reservoir in KeKeYa gas field, Northwest china. The results of oil/gas reserves, variations of stratum pressure and oil/gas production, etc. are compared with the observation Good agreement comparable to COMP4 model is achieved, suggesting that the present model is both efficient and powerful in compositional reservoir simulations.
