Abstract
Abstract Catalysts particularly useful for hydroreforming and isomerization of hydrocarbons formed of a refractory mineral oxide carrier having a halogen in combined form and the following metals in free or combined state: A. A metal from the platinum group (0.02 to 2%); B. tin (0.02 to 2%); and C. at least one metal selected from the group of scandium, yttrium, thorium, uranium, and the rare earths metals (0.01 to 5%) -- said percentages being based upon the total weight of the catalyst, said catalyst preferably having platinum and chlorine. Also the use of said catalyst in the aforementioned hydrotreatments.
