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.
