Abstract:
Multi-reactor systems with aromatization reactor vessels containing a catalyst with low surface area and pore volume, followed in series by aromatization reactor vessels containing a catalyst with high surface area and pore volume, are disclosed. Related reforming methods using the different aromatization catalysts also are described.

Claim (Index 1):
An aromatization process comprising:\n (i) introducing a first hydrocarbon feed into at least one first reactor vessel comprising a first aromatization catalyst, and contacting the first hydrocarbon feed with the first aromatization catalyst under first reforming conditions to produce a first aromatic product; wherein: the first aromatization catalyst comprises platinum and a first catalyst support, the first aromatization catalyst characterized by: a first surface area in a range from about 80 m 2 /g to about 150 m 2 /g; and/or a first micropore volume in a range from about 0.01 cc/g to about 0.048 cc/g; (ii) discharging a first effluent comprising the first aromatic product from the at least one first reactor vessel; (iii) heating the first effluent to form a second hydrocarbon feed; (iv) introducing the second hydrocarbon feed into at least one second reactor vessel comprising a second aromatization catalyst, and contacting the second hydrocarbon feed with the second aromatization catalyst under second reforming conditions to produce a second aromatic product; wherein: the second aromatization catalyst comprises platinum and a second catalyst support, the second aromatization catalyst characterized by: a second surface area in a range from about 160 m 2 /g to about 260 m 2 /g; and/or a second micropore volume in a range from about 0.05 cc/g to about 0.09 cc/g; and (v) discharging a second effluent comprising the second aromatic product from the at least one second reactor vessel, wherein: the first aromatization catalyst is a regenerated catalyst; the first aromatization catalyst has a lower platinum dispersion than that of the second aromatization catalyst and the first aromatization catalyst has an aromatics selectivity that is substantially the same as or better than that of the second aromatization catalyst.
