Abstract
Process for producing aromatic hydrocarbons from gasolines substantially free of mono- and diolefins, comprising an aromizing step in the presence of a catalyst at a temperature from 400.degree. to 600.degree. C under a pressure from 1 to 30 kg/cm.sup.2 followed with the separation of an aromatic cut and of an alkylaromatic cut and a step of hydrodealkylating said alkylaromatic cut by means of hydrogen recovered from the aromizing step, in the presence of a catalyst, at a temperature from 400.degree. to 650.degree. C, under a pressure substantially equal or lower than that of the aromizing step.
