Abstract

An improved process for the manufacture of aromatic hydrocarbons not substituted by hydrodealkylation in the presence of a molecular hydrogen-containing gas, of a new charge containing at least one alkylaromatic hydrocarbon, in which process at least a part of the polynuclear heavy aromatic products obtained is recycled by way of by-products, characterized in that at least 60% of the recycled heavy products are brought into contact in a hydrodealkylation zone with at least 20% of the total hydrogen used, before the mixture obtained is put in contact with most of the new cargo to be treated.
