Abstract

The present invention relates to a process for the hydrogenation of substituted or unsubstituted, monocyclic or polycyclicaromatics to form the corresponding cycloaliphatics, in particular of benzene to cyclohexane, by bringing the aromatic into contact with a hydrogen-containing gas in the presence of a catalyst, where hydrogen in which residual gases are present is used.
