چکیده مقاله:
Ni-W/HZSM5-HMS catalysts were evaluated for benzene hydrogenation reaction at 130–190 oC. Kinetics of benzene hydrogenation was investigated under various hydrogen and benzene pressures and the effect of reaction conditions on catalytic performance was studied. The results showed that these catalysts have a good ability for this reaction. For more study, two kinetic models have been selected and tested to describe the kinetics for this reaction. Both used models, the power law and Langmuir-Hinshelwood, provided a good fit towards the experimental data and allowed to determine the kinetic parameters. The kinetics evaluations were shown that the catalyst with Ni/W=1.5 could perform this hydrogenation reaction with appropriate rate.
