Abstract
In a process for the transalkylation of polycyclohexylbenzenes, a feed containing at least one polycyclohexylbenzene is contacted with benzene under transalkylation conditions with a catalyst comprising a zeolite USY having a silica to alumina molar ratio in excess of 10 to convert at least part of said polycyclohexylbenzene to cyclohexylbenzene.
