摘要/Abstract

摘要： The kinetics of liquid-phase hydrogenation of benzene in misch metal nickel-five (MlNi5)
and benzene slurry system was studied by investigating the influences of the reaction
temperature, pressure, alloy concentration and stirring speed on the mass transfer-reaction
processes inside the slurry. The results show that the whole process is controlled by the
reaction at the surface of the catalyst. The mass transfer resistance at gas-liquid
interface and that from the bulk liquid phase to the surface of the catalyst particles are
negligible. The apparent reaction rate is zero order for benzene concentration and first
order for hydrogen concentration in the liquid phase. The kinetic model obtained fits the
experimental data very well. The apparent activation energy of the hydrogen absorption
reaction of MlNi5-C6H6 slurry system is 42.16 kJ.mol-1.
