摘要

Abstract

This report aims to reduce the benzene in a mixture of benzene and toluene as a model reaction using catalytic hydrogenation. In this research

we developed a series of catalysts with different supports such as Ni/HMS

Ni/HZSM-5

Ni/HZSM5-HMS

Ni/Al

and Ni/SiO

. Kinetic of this reaction was investigated under various hydrogen and benzene pressures. For more study

two kinetic models have also been selected and tested to describe the kinetics for this reaction. Both used models

the power law and Langmuir-Hinshelwood

provided a good fit toward the experimental data and allowed to determine the kinetic parameters. Among these catalysts

Ni/Al

showed the maximum benzene conversion (99.19%) at 130℃ for benzene hydrogenation. The lowest toluene conversion was observed for Ni/SiO

. Furthermore

this catalyst presented high selectivity to benzene (75.26%) at 130℃. The catalytic performance (activity

selectivity and stability) and kinetics evaluations were shown that the Ni/SiO

is an effective catalyst to hydrogenate benzene. It seems that the surface properties particularly pore siz

e are effective parameter compared to other factors such as acidity and metal dispersion in this process.
