ABSTRACT:
Process for the preparation of cycloaliphatic hydrocarbons by gas phase hydrogenation of aromatic hydrocarbons in the presence of palladium catalyst, characterized in that palladium catalyst is used which contains the palladium applied to a support which comprises aluminium oxide of which at least 20% by weight, relative to the weight of the support, has been converted to lithium-aluminium spinel. The gas phase hydrogenation can be carried out at atmospheric pressure.
