چکیده مقاله:
This report aims to reduce the benzene 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/Al2O3 and Ni/SiO2. The various Ni-supported catalysts were evaluated for the hydrogenation reaction of benzene at 130–190 oC. The results showed that Ni/Al2O3 catalyst has better ability than other prepared catalysts for this reaction, such as a maximum benzene conversion (>99%), good cyclohexane selectivity (>55%), the best yield (>52%) and appropriate catalytic stability against coke deposition. It seems that the catalytic acidity is effective parameter compared to other factors such as surface properties and metal dispersion.
