| abstract |
A process for producing benzene is provided which comprises the steps of subjecting a charge rich in alkylaromatic hydrocarbons and containing 2-20% by weight paraffinic and/or naphthenic hydrocarbons, in a first catalytic zone, to a hydrotreatment in the presence of a catalyst mixture containing a selective mordenite catalyst and a reforming catalyst, then subjecting at least a portion of the resultant effluent to thermal or catalytic hydrodealkylation in a second zone, and separating and recovering benzene from the effluent from the second zone. |
