Abstract
A catalyst useful for the hydrotreatment of hydrocarbons comprising, on a refractory inorganic oxide support, the following metals: (a) from 0.02 to 2% of at least one platinum metal; (b) from 0.02 to 2% of at least one metal belonging to the group consisting of zirconium, titanium, and tungsten; (c) from 0.02 to 2% tin. This catalyst is preferably halogenated, typically with chlorine, from 0.4 to 2%. Catalysts according to this invention are particularly useful for isomerization of a charge of alkylaromatic hydrocarbons, and particularly those having eight carbon atoms. The preferred isomerization catalyst is a platinum, tin and zirconium trimetallic catalyst halogenated with chlorine approximately from 1 to 2% based on the total catalyst weight. Said catalysts are also useful for hydroreforming and aromatizing being surprisingly superior for all these types of reactions.
