Abstract

A process for hydrogenating an unsaturated heterocyclic compound or a mixture of two or more thereof by contacting the unsaturated heterocyclic compounder the mixture of two or more thereof with a hydrogen-containing gas in the presence of a catalyst comprising as active metal at least one metal from transition group VIII of the Periodic Table, applied to a support, wherein the support has macropores.
