Abstract
Abstract A process for hydrogenating hydrocarbons and mixtures of hydrocarbons utilizing a catalytic composite of a porous carrier material, a rhenium component, a germanium component and a Group VIII noble metal component. A specific example of one such process involves the hydrogenation of benzene to produce cyclohexane.
