Hydrogenolysis of methylcyclohexane was studied over molybdenum and tungsten di-tri oxides. The products obtained were 2 methylhexane, 3-methylhexane and n-heptane and dimethylpentanes (DMPs). The oxides were characterized before and after reduction by XRD, N2 sorption and SEM. Molybdenum oxides were reduced 12 h at 400 °C while tungsten oxides at 500 °C. We noticed that selectivity to ring opening on molybdenum oxides is minority, while the isomerization to dimethylcyclopentanes and ethylcyclopentane is the main reaction. On the tungsten oxides, the ring opening reaction occurred with the formation of DMPs although the isomerization, the aromatization and the cracking reactions are dominant.
