Abstract Benzene hydrogenation in the BTX mixture over various carbonaceous catalysts was evaluated in the range of 130–190 °C and at the variable partial pressure of the hydrogen (2.3–5.2 Pa) and benzene content (2–8 vol%). Under these conditions, the best activity was obtained for Ni-graphene at 190 °C with over 94% conversion. The highest selectivity to cyclohexane (>60%) is related to Ni-activated carbon at 170 °C. To determine the kinetics parameters, Power-Law and Langmuir–Hinshelwood models have been tested. These models, provided a good fit toward the experimental data and allowed to determine the kinetics parameters that are in good agreement with both models.
