Abstract
Abstract A process for the preparation of aromatic compounds is set forth which involves contacting a feed consisting essentially of C2-C4 paraffins and/or olefins with a crystalline aluminosilicate of the ZSM-5 type and recovering the aromatics produced. The described process can be carried out in the absence of a hydrogenation/dehydrogenation component and in the absence of added hydrogen.
