Abstract
A hydrocarbon feedstock is catalytically reformed in a sequence comprising a continuous-reforming zone associated with continuous catalyst regeneration, a zeolitic-reforming zone containing a catalyst comprising a platinum-group metal and a nonacidic L-zeolite and an aromatics-isomerization zone containing a catalyst comprising a platinum-group metal, a metal attenuator and a refractory inorganic oxide. The process combination features high selectivity in producing a high-purity BTX product from naphtha.
