For chemical hydrides such as cyclohexane, methylcyclohexane etc., which are being considered as a promising carrier for hydrogen storage and transportation, highly efficient recovery of hydrogen from themselves should be desired. Common problems involving the processes dealing with chemical compounds are 1) that the reaction is limited by thermodynamic equilibrium and 2) that hydrogen must be separated from the gaseous mixture of the products. To solve these problems simultaneously, a palladium membrane reactor capable of upsetting the chemical equilibrium and moreover recovering hydrogen of high purity is employed. Experiment shows that more than 80% of the hydrogen recovery can be obtained at 4 bar of the reaction pressure at 300°C for cyclohexane dehydrogenation.
