The present invention relates to hydrogenation processes including: contacting a first composition with hydrogen under hydrogenation conditions, in the presence of an eggshell hydrogenation catalyst, wherein the first composition has: (i) greater than about 50 wt % of cyclohexylbenzene, the wt % based upon the total weight of the first composition; and (ii) greater than about 0.3 wt % of cyclohexenylbenzene, the wt % based upon the total weight of the first composition; and thereby obtaining a second composition having less cyclohexenylbenzene than the first composition. Other hydrogenation processes are also described.
