Abstract
Disclosed is an improvement in a process for production of cyclohexane by liquid phase hydrogenation of benzene wherein no diluent is necessary, which comprises contacting benzene and hydrogen in the presence of a mixed catalyst bed comprising a first catalyst which is a less active hydrogenation catalyst selected from elements of Group VIII of the Periodic Table and a second, more active catalyst, comprising a Group VIII metal supported on an oxide, such as, for example, alumina, silica or titania at a temperature of about 40.degree. C. to about 300.degree. C. and pressure sufficient to keep the benzene liquid at the chosen reaction temperature.
