Title: Process for producing aromatic hydrocarbons of high purity. [from gasoline]

Abstract

A process is described for producing aromatic hydrocarbons from gasolines substantially free of mono- and diolefins. It comprises an aromizing step in the presence of a catalyst at a temperature from 400 to 600/sup 0/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 to 650/sup 0/C, under a pressure substantially equal or lower than that of the aromizing step.
