Abstract: The invention relates to a method for hydrogenating substituted or 5 unsubstituted mononuclear or multinuclear aromatics to form corresponding cycloaliphatics, especially benzole to form cyclohexane, by bringing the aromatic into contact with a gas containing hydrogen in the presence of a catalyst, using hydrogen containing residual gases.
