| 英文摘要 | a ru/al2o3/cordierite monolithic catalyst was prepared, characterized, and examined in selective hydrogenation of benzene to cyclohexene in a monolithic fixed-bed reactor with an aqueous solution of znso4. the carberry number and wheeler-weisz group were calculated to analyze the effects of external and internal diffusions of h-2, benzene, and cyclohexene. according to the results of calculations, the water film, solubility, and diffusion coefficients of the three reactants (h-2, benzene, and cyclohexene) play important roles in the mass-transfer rate. under proper reaction conditions, the effects of the external mass transfer of h-2 and benzene on the reaction rate are negligible. for the hydrogenation of cyclohexene, the diffusion of cyclohexene from the organic phase to the catalyst is the limiting step in the presence of water, which is the most important factor for obtaining high cyclohexene selectivity. the absence of pore diffusion of the three reactants, which is attributed to the thin eggshell distribution of in the catalyst, is another important factor for the higher cyclohexene selectivity. in addition, the optimum reaction conditions were found to be 413-423 k and 5 mpa. |
