Benzene hydrogenation over zeolite supported platinum catalysts; particularly the effect of catalyst preparation procedures was studied. It was found that Pt/zeolite prepared with wet solution ion exchange procedure using cationic platinum precursors showed the best catalytic performances. The potential of Pt/beta in catalyzing benzene hydrogenation-naphthene isomerization cascaded reaction was demonstrated, showing the highest methyl-cyclopentane to cyclohexane product ratio comparable to the thermodynamic equilibrium value, the lowest cracking gas yield and a maximum octane barrel number.
