•Methylcyclohexane ring opening using Rh–Pd supported on SiO2/Al2O3 was studied.•Total and the Brønsted acidity have a higher influence on the activity for decalin ring opening than for single ring opening.•The influence of the metal charge is more important on the reaction of MCH.•All the catalysts display a high MCH conversion which increases with the reaction temperature.•Catalysts with Rh/Pd = 2 and monometallic Rh1 supported on SIRAL 40 has the highest yield to ring opening products.
Monometallic and bimetallic Pd–Rh catalysts with various Rh/Pd atomic ratios (=0.5, 1 and 2) and a total metal charge of 1 wt% supported on SiO2–Al2O3 (SIRAL 40, 20, 5) were studied for the ring opening of methylcyclohexane (MCH). The results were compared with those obtained previously for ring opening of decalin. It was found that the total acidity and the Brønsted acidity of the support have a higher influence on the activity for ring opening of naphthenic bicycles than on the activity for opening single rings. The influence of the metal charge is more important on the reaction of MCH. All the catalysts display a high MCH conversion, which increases with the reaction temperature. The bimetallic catalyst with the Rh/Pd ratio equal to 2 and supported on SIRAL 40 has the highest yield to ring opening products.
