ABSTRACT:
The present invention relates to an improvement in a process for the conversion of benzene in gas-phase to cyclohexane under a suitable operation conditions by hydrogenation over a specific supported nickel catalyst located on a fixed bed reactor, the improvement comprising that the specific supported nickel catalyst is a nickel catalyst supported by a mixture of titanium dioxide and zirconium dioxide. The present invention also relates to the operation condition for the hydrogenation of benzene, the optimal components of the catalyst used, process for the preparation of said specific supported catalysts and the conditions for pretreatment.
