PROCESS FOR PREPARING CATALYSTS CONTAINING A METAL OF THE PLATINUM GROUP, AND USES THEREOF

摘要

A process is described for the preparation of a catalyst containing at least one metal of the platinum group deposited on an alumina support, said process consisting of depositing the metal of the platinum group in two steps, the first one being followed by a calcination and a reduction, the second one being followed by a calcination. The catalyst may be used in the dehydrogenation of aliphatic hydrocarbons having 3 to 6 carbon atoms.
