Abstract
A hydrocarbon feedstock is catalytically reformed in a sequence comprising 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 medium-pore molecular sieve, a platinum-group metal and a refractory inorganic oxide. Optionally, the zeolitic-reforming zone is preceded by a continuous-reforming zone associated with continuous catalyst regeneration, The process combination features high selectivity in producing a high-purity BTX product from naphtha.
