| 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 | Synthesis of light hydrocarbons from CO hydrogenation over Co_xMn_(0.06)/SiO_2显示文摘A series of CoxMn0.06/SiO2 catalysts were prepared by an impregnation method for catalytic hydrogenation of CO to Light Hydrocarbons(LHCs).The catalysts were characterized by XRD,SEM,N2 adsorption and NH3-TPD techniques.Catalyst activities were evaluated in a high-pressure micro reactor.The results show that the performance of the catalysts was significantly affected by the amount of Co loaded onto the substrate.The activity of the Co0.10Mn0.06/SiO2 catalyst was stable with time-on-stream.The CO conversion and LHCs selectivity were 95.3% and 98.1%,respectively,for this catalyst at 400 °C. | ZHAO, Jianjun ZONG, Zhimin XIE, Hengsen LIU, Tong LI, Jianjun WANG, Taotao WEI, Xianyong | 2010 | Mining Science and Technology2010，20，2： | 1 |
