Abstract
A process for selectively hydrogenating benzene in a hydrocarbon oil is disclosed. The process comprises reacting the hydrocarbon oil with hydrogen gas in the presence of a hydrogenation catalyst comprising at least one metal in Group VIII of the Periodic Table and an alkaline aqueous layer which contains zinc or a zinc compound. Benzene in hydrocarbon oils can be selectively converted into cyclohexane by the process, while suppressing the hydrogenation reaction of alkyl aromatic compounds which are important high octane materials for gasoline.
