| 1 | Microwave-assisted hydroxylation of benzene to phenol with H_2O_2 over FeSO_4/SiO_2显示文摘Hydroxyl radicals HO are generated under Fenton-like (Fe2++H2O2→HO?+OH?+Fe3+) catalytic conditions upon microwave irradiation. Liquid-phase direct catalytic oxidation of benzene to phenol was obtained using FeSO4 supported on silica gel as a solid catalyst and hydrogen peroxide as the oxidant. The effects of various parameters, such as the different solvents, the amount of solvent used, the amount of catalyst used, the reaction time, the reaction temperature and the amount of hydrogen peroxide used on the yield of phenol were studied to identify optimum reaction conditions. Conventionally heated reaction gives a phenol yield of 0.6%. A higher phenol yield of 13.9% with a selectivity of 100% is obtained when the reaction mixture was irradiated with micro-wave energy. It is concluded that microwave irradiation offers more effective control of energy input for hydroxyl radical generation that is appropriate for various synthetic reactions. | LIU Tong WEI Xianyong ZHAO Jianjun XIE Hengsen WANG Taotao ZONG Zhimin | 2010 | Mining Science and Technology2010，20，1： | 4 |
| 2 | CO2-hierarchical activated carbon prepared from coal gasification residue: Adsorption equilibrium, isotherm, kinetic and thermodynamic studies for methylene blue removal显示文摘Mineral matter in a residue(RC G)from coal gasification(CG)was removed by two-stage acid leaching.Hierarchical activated carbon(HAC)was prepared by activating RC Gwith CO2.The performance of HAC on removing methylene blue(MB)from an aqueous solution was investigated.HAC was characterized by N2 adsorption–desorption isotherm,Fourier transform infrared spectroscopy,and scanning electron microscopy.The results show that HAC exhibits hierarchical pore structure with high specific surface area(862.76 m2·g-1)and total pore volume(0.684 cm3·g-1),and abundant organic functional groups.The adsorption equilibrium data of MB on HAC are best fitted to the Redlich-Peterson.The kinetic data show that the pseudo-first-order model is more suitable at low MB concentration,while the advantages of the pseudo-second-orderand the Elovich models are more obvious as the concentration increases.According to the thermodynamic parameters,the HAC-MB adsorption process is spontaneous and endothermic. | Yuhong Kang Xianyong Wei Guanghui Liu Miao Mu Xiangrong Ma Yong Gao Zhimin Zong | 2020 | Chinese Journal of Chemical Engineering2020，28，6： | 2 |
| 3 | An evidence for the strong association of N-methyl-2-pyrrolidinone with some organic species in three Chinese bituminous coals显示文摘Three Chinese bituminous coals collected from Shenfu, Heidaigou and Feicheng coal fields were re- spectively extracted with carbon-disulfide/N-methyl-2-pyrrolidinone (CS2/NMP) mixed solvent (volume ratio 1:1) at room temperature followed by distillation of CS2 under ambient pressure and subsequent removal of most of NMP by distillation at 110℃ under reduced pressure to afford mixed sol- vent-extractable fractions (MSEFs) with small amount of NMP. Acetone-extractable fraction 1 (AEF1) was obtained by extracting each MSEF under ultrasonic irradiation at room temperature and subse- quently using a Soxhlet extractor. Direct extraction of each bituminous coal affords acetone-soluble fraction 2 (AEF2). GC/MS analysis shows that m/z of base or secondary peak in mass spectra of a se- ries of components from each AEF1 is 98, whereas such components were not detected in AEF2. Since m/z of base peak in mass spectrum of NMP itself is 99, the base or secondary peak at m/z 98 should result from loss of α-H from NMP, i.e., NMP is strongly associated with some organic species (OSs) and thereby the components detected with base or secodary peak at m/z 98 in their mass spectra should be associated NMP-OS. | LIU ChanMin ZONG ZhiMin JIA JiXian LIU GuangFeng WEI XianYong | 2008 | Chinese Science Bulletin2008，53，8： | 2 |
| 4 | Insight into the structural features of organic species in Fushun oil shale via thermal dissolution显示文摘Fushun oil shale(FOS) was subjected to thermal dissolution(TD) under different conditions. The results show that the optimal solvent, temperature, time, and ratio of solvent to FOS are ethanol, 300 °C, 2 h, and 5 ml·g^(-1),respectively and the corresponding yield of the soluble portion(SP) is 32.2%(daf), which is much higher than the oil content of FOS(ca. 6%), suggesting that TD in ethanol is an excellent way to extract organics from FOS.According to 3 direct analyses, aliphatic moieties in FOS are the most abundant followed by C\\O-containing moieties and each cluster in FOS has 3 conjugated aromatic rings on average with fewer substituents. According to the analysis with a gas chromatograph/mass spectrometer, alkanes are predominant in all the SPs. A number of alkenes were identified in the SPs from the TD, while none of the alkenes were detected in acetone-SP obtained at room temperature, implying that the TD can destroy the π-π and intertwining interactions between alkenes and macromolecular structures in FOS. Moreover, a small amount of alkyl-substituted phenols and alkoxysubstituted phenols were detected in ethanol-SP from the TD, which could be the products from ethanolyzing the macromolecular moiety of FOS. | Shengkang Wang Xianyong Wei Zhimin Zong | 2018 | Chinese Journal of Chemical Engineering2018，26，10： | 2 |

| 6 | Synthesis of light hydrocarbons over Fe/AC catalysts显示文摘A series of Fe/AC catalysts for catalytic hydrogenation of CO to light hydrocarbons(LHCs) were prepared by decomposing Fe(CO)5 in an autoclave.The catalysts activities were tested in a high-pressure micro reactor.The results show that both CO conversion and LHCs selectivity were significantly affected by the amount of Fe loaded onto the catalysts.The optimum Fe content was determined to be 10% by weight of the catalyst.Over the corresponding catalyst(i.e.,10% Fe/C catalyst),the conversion of CO and the selectivity of LHCs were 94.8% and 59.2%,respectively,at 360 °C.Based on various catalyst characterization techniques,such as XRD,BET and SEM,the catalysts surface areas and pore volume decreased and the smaller particles agglomerated at the edges and corners in the outer region of the support with the increasing Fe content.The agglomerated particles increased greatly when the iron content of the catalyst was higher than 10%.The decrease of catalyst activity can be due to the agglomerated particles. | Zhao Jianjun Zong Zhimin Wang Taotao Liu Tong Wei Xianyong | 2012 | International Journal of Mining Science and Technology2012，22，2： | 1 |
