Based on the developed model, the theoretical phenol Conversions at steady state could be calculated using the kinetic parameters obtained from the previous batch experiments. The theoretical conversions are in good agreement with the experimental data obtained in the submerged catalysis/MF system within relative error of ±5%. The model can be used to determine the optimal experimental conditions to carry out the phenol hydroxylation over TS-1 in the submerged catalysis/MF system.展开更多

Compared with traditional catalytic oxidation （TCO） mode, Mn/A12O3 membrane catalytic system had much higher removal efficiency of Hg^0. After the incorporation of Mo and Ru, the production of C12 from the Deacon reaction and the retainability for oxidants over Mn/A12O3 membrane were greatly enhanced. As a result, the oxidization of Hg^0 over Mn/A12O3 membrane was obviously promoted due to incorporation of Mo and Ru. In the presence of 8 ppmv HC1, the removal efficiency of Hg^0 by Mn/Mo/Ru/A12O3 membrane reached 95% at 423 K. The influence of NO and SO2 on Hg^0 removal were insignificant even if 200 ppmv NO and 1000 ppmv SO2 were used. Moreover, compared with the TCO mode, the Mn/Mo/Ru/A12O3 membrane catalytic system could remarkably reduce the demanded amount of oxidants for Hg^0 removal. Therefore, the Mn/Mo/Ru/A12O3 membrane catalytic system may be a promising technology for the control of Hg~ emission.展开更多
