International audienceThe catalytic total oxidation of toluene is used to bring the required calories to restore hydrogen from methylcyclohexane (MCH). Two coupled reactions, both catalyzed by Pt/alumina, are thus considered in one autothermal heat-exchanger reactor (HER): endothermic dehydrogenation of methylcyclohexane and catalytic combustion of less than 10% of produced toluene (6% for the chemical reaction, about 4% for heat losses). Both reactions are carried out at 350 °C. Methylcyclohexane and toluene light-off curves have been performed in one elementary module. Methylcyclohexane combustion has been eliminated due to its safety drawbacks, although the MCH combustion provides best stability to autothermal HER
