METHOD FOR PRODUCING AROMATICS, IN PARTICULAR BENZOL, BY THE AROMATISATION OF NON-AROMATICS USING WATER VAPOUR AND THE SUBSEQUENT DEALKYLATION OF ALKYL-SUBSTITUTED AROMATIC HYDROCARBONS USING HYDROGEN

摘要

The invention relates to a method for the dealkylation of alkyl-substituted aromatic hydrocarbons. According to said method, in step (I), non-aromatic hydrocarbons comprising 6 or more carbon atoms are aromatised in the presence of water vapour and a catalyst and in step (II) at least part of the product stream obtained in step (I), said stream containing alkyl-substituted aromatic hydrocarbons, is converted with the aid of hydrogen, optionally in the presence of a catalyst, dealkylating the alkyl-substituted aromatic hydrocarbons.
