Abstract

Catalytic process for steam dealkylation of a charge containing at least one alkyl aromatic hydrocarbon, such as a charge issued from effluents of units for catalytic reforming or for producing aromatic hydrocarbons, wherein the catalyst contains an alumina carrier, from 0.1 to 1% of rhodium, from 0.05 to 1% of TiO.sub.2 and optionally from 0.1 to 1% of ruthenium, palladium, iridium, platinum or osmium and/or from 0.01 to 5% of lithium, sodium, potassium, rubidium or cesium.
