Abstract
Alkylaromatic hydrocarbons are steam-dealkylated in the presence of a catalyst comprising an alumina carrier and 0.1 to 2% b.w. of a group VIII noble metal, 0.05 to 2% of a group I.sub.B metal and 0.01 to 5% of an alkali metal.

A process for steam-dealkylating a feedstock comprising at least one alkylaromatic hydrocarbon, in the presence of a catalyst comprising an alumina carrier and, by weight with respect to the catalyst, 0.1 to 2% of at least one group VIII noble metal, selected from ruthenium, rhodium, palladium, osmium, iridium and platinum, 0.05 to 2% of at least one metal from group I.sub.B, selected from copper, silver and gold and 0.01 to 5% of at least one alkali metal selected from lithium, sodium, potassium, rubidium and cesium.
