Abstract
A processing step is added to an existing catalytic reforming unit to increase the yield of aromatic product. The additional processing comprises separation of product from the reforming unit into an aromatic concentrate and a low-octane recycle stream which is upgraded by aromatization. The separation preferably is effected using a large-pore molecular sieve, and the aromatization with a nonacidic L-zeolite contained within the hydrogen circuit of the existing catalytic reforming unit.
