Commercial Application of the XYA-5 Catalyst in Acrylonitrile Unit

引用

China Petroleum Processing & Petrochemical Technology 2008年第4期10卷 13-17页

作者： Li Zhengguang PetroChina daqing refining and Chemieal company Daqing 163411

The XYA-5 catalyst was first applied in commercial scale on an 80-kt/a acrylonitrile unit at the daqing refining and chemical company. Test results had shown that the once-through yield of acrylonitrile exceeded 80% with the unit consumption ofpropylene reaching 1032 kg on each ton of acrylonitrile. The product quality could be easily put under control and the distribution of reaction products was reasonable with good cleaning performance and stability of the catalyst that was suitable for use on this commercial unit.

Simultaneous removal of COD and nitrogen using a novel carbon-membrane aerated biofilm reactor

引用

Journal of Environmental Sciences 2008年第2期20卷 142-148页

作者： HU Shaowei YANG Fenglin SUN Cui ZHANG Jianye WANG Tonghua School of Environmental and Biological Science and Technology Dalian University of Technology Dalian 116024 China daqing refining and chemical company Daqing 163411 China School of chemical Engineering Dalian University of Technology Dalian 116024 China

A membrane aerated biofilm reactor is a promising technology for wastewater treatment. In this study, a carbon-membrane aerated biofilm reactor （CMABR） has been developed, to remove carbon organics and nitrogen simultaneously from one reactor. The results showed that CMABR has a high chemical oxygen demand （COD） and nitrogen removal efficiency, as it is operated with a hydraulic retention time （HRT） of 20 h, and it also showed a perfect performance, even if the HRT was shortened to 12 h. In this period, the removal efficiencies of COD, ammonia nitrogen （NH4^＋-N）, and total nitrogen （TN） reached 86%, 94%, and 84%, respectively. However, the removal efficiencies of NH4^＋-N and TN declined rapidly as the HRT was shortened to 8 h. This is because of the excessive growth of biomass on the nonwoven fiber and very high organic loading rate. The fluorescence in situ hybridization （FISH） analysis indicated that the ammonia oxidizing bacteria （AOB） were mainly distributed in the inner layer of the biofilm. The coexistence of AOB and eubacteria in one biofilm can enhance the simultaneous removal of COD and nitrogen.

Effect of acid density of HZSM-5 on the oligomerization of ethylene in FCC dry gas

引用

Journal of Natural Gas Chemistry 2009年第2期18卷 156-160页

作者： Xue Ding Shan Geng Chunyi Li Chaohe Yang Guohui Wang State Key Laboratory of Heavy Oil Processing China University of Petroleum （East China） Qingdao 266555 Shandong China daqing refining ＆ chemical company CNPC Daqing 163411 Heilongjiang China

The oligomerization of ethylene in FCC dry gas over HZSM-5 catalyst with different Si/A12 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 0.14mmolNH3/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.

Dendritic molecules with dodecyl groups as the hyperbranchs were synthesized in methanol by Michael addition with dodecylamine and methyl acrylate as raw materials. This new-type dendritic molecules were called vividly ＂broom molecules＂ in this report. The surface tension of the aqueous solution of broom molecule terminated amino group was measured by using the dropvolume method. The demulsification performance of the broom molecules for the oil/water （O/W） simulated crude oil emulsion was examined. The experimental results revealed that, as a new-type of surfactants, the broom molecules terminated amino groups showed demulsification for the O/W simulated crude oil emulsion. 2007 Jun Wang.

Analysis of Causes Leading to High Bromine Number of C_8^+ Aromatics and Short Clay Service Life and Countermeasures Proposed

引用

China Petroleum Processing & Petrochemical Technology 2007年第2期9卷 23-28页

作者： Li Yousong Ni Xiaoliang Yah Jun SINOPEC Zhenhai refining and chemical Branch company Ningbo 315207

After comparing the operating status of other catalytic reforming units and evaluation of the side-cut stream tests, the refinery investigated the influence of the feedstock property, clay types, and operating regime of the clay tower and catalytic reforming unit on the service life of the clay. Test results had revealed that the low potential aromatic content of the reformer feed and high operating severity were the critical causes leading to high bromine number of the C8^＋ aromatics feed for the PX unit and the shortened service life of clay. This article also puts forward the corresponding remedial measures.

Nanocrystalline ZSM-5(with a crystal size in the range of 20—30 nm) has been synthesized in only 20 h via the crystallization of ultra-concentrated homogeneous synthesis mixtures. The influence of low water content, use of compound surfactant, a proper crystallization time and SiO_2/Al_2O_3 molar ratio on the properties of the final nanocrystalline ZSM-5 has been studied. Especially, the use of compound surfactant has influenced some properties of nano-ZSM such as the morphology, crystal size and crystallization greatly. The nano-ZSM-5 zeolite was investigated using XRD, BET, SEM, NH_3-TPD, and other techniques. The evaluation results in a 200-mL hydrogenation unit indicated that the synthesized nano-ZSM-5 had excellent catalytic performance in diesel hydrodewaxing.

Novel BiVO4@C3N4@GO Composites with Higher Photocatalytic Performance

China Petroleum Processing & Petrochemical Technology 2019年第2期21卷 50-57页

BiVO4, BiVO4@C3N4 and BiVO4@C3N4@GO composite photo-catalysts were synthesized, and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), transmission electron microscopy (TEM), ultraviolet-visible diffuse reflectance spectroscopy (UV-vis DRS), Fourier transform infrared spectroscopy (FT-IR), and Brunauer-Emmett-Teller (BET) surface area techniques. The photocatalytic activity was evaluated on the degradation of methylene blue (MB) under visible light irradiation, which denoted that the BiVO4@C3N4@GO ternary composite outperformed the binary composite BiVO4@C3N4 and BiVO4. Then the effects of catalyst dosage, initial pH value, and initial methylene blue concentration on the degradation process were investigated systematically. The improvement of visible-light photocatalytic degradation performance was attributed to the enhanced visible light absorption, larger surface area, higher adsorption ability, and prolonged lifetime of photo-generated electron-hole pairs. The recycle experiments results showed that the BiVO4@C3N4@GO composite had excellent photo-stability for MB photocatalytic degradation.
