METHOD FOR THE AROMATISATION OF NON-AROMATICS AND THE SUBSEQUENT DEALKYLATION OF ALKYL-SUBSTITUTED AROMATIC HYDROCARBONS USING WATER VAPOUR

摘要

The invention relates to a method for dealkylating 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 water vapour in the presence of a catalyst, dealkylating the alkyl-substituted aromatic hydrocarbons.
