Fractionated pyrolysis gasoline containing toluene, xylenes, ethylbenzenes, C7-C9 paraffins, olefins and naphthenes are selectively hydrodealkylated and transalkylated to give ethylbenzene-lean xylenes and benzene in the presence of a catalyst comprising a tungsten/molybdenum component of WO3 and MoO3 and an acidic component of 60 (wt)% of mordenite and 40 (wt)% of catalytically active alumina. |
