摘要
The macro-kinetics of benzene hydrogenation over porous Ni/γ-Al<sub>2</sub>O<sub>3</sub> catalyst was measured with asingle-pellet diffusion reactor.Based on the dusty-gas model,the differential equations by taking into account ofthe variation of effective diffusivities with the composition were derived to describe the diffusion and reactionprocesses of reacting species over porous catalyst.Using the tortuosity factors determined under the condition ofsteady physical diffusion,the global reaction rates were calculated by solving the equations,and the results are ingood agreement with the experimental data obtained.
The macro-kinetics of benzene hydrogenation over porous Ni/γ-Al2O3 catalyst was measured with a single-pellet diffusion reactor. Based on the dusty-gas model, the differential equations by taking into account of the variation of effective diffusivities with the composition were derived to describe the diffusion and reaction processes of reacting species over porous catalyst. Using the tortuosity factors determined under the condition of steady physical diffusion, the global reaction rates were calculated by solving the equations, and the results are in good agreement with the experimental data obtained.
