Abstract: Production of motor gasoline and a BTX-enriched reformate by fractionating a naphtha feedstock into a mid-boiling BTX-precursor fraction, a relatively high-boiling fraction and a relatively low-boiling fraction; catalytically reforming the BTX-precursor fraction in a first reforming zone; combining the relatively high-boiling and low-boiling fractions and catalytically reforming the combined fractions in a second reforming zone.

Abstract: An improved reforming process for producing aromatic hydrocarbons is disclosed. The process includes two reformers arranged in parallel flow configuration, with the first reformer being a conventional reformer comprising a catalyst selective for reforming C8+ hydrocarbons to a reformate and the second reformer comprising a catalyst selective for reforming C7− hydrocarbons to a reformate. In certain embodiments, the first reformer catalyst comprises a conventional alumina catalyst and the second reformer catalyst comprises a ZSM-5 catalyst.

Abstract: The present disclosure relates generally to processes and systems for producing liquid transportation fuels by converting a feed stream that comprises both isopentane and n-pentane, and optionally, some C6+ hydrocarbons. Isopentane and smaller hydrocarbons are separated to form a first fraction while n-pentane and larger components of the feed stock form a second fraction. Each fraction is then catalytically-activated in a separate reaction zone with a separate catalyst, where the conditions maintained in each zone maximize the conversion of each fraction to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. In certain embodiments, the first fraction is activated at a lower temperature than the second fraction. The process provides increased yields of upgraded hydrocarbon products that possess the characteristics of a liquid transportation fuel or a blend component thereof.

Certain embodiments additionally comprise mixing at least a portion of the two effluents and contacting with an oligomerization catalyst to provide enhanced yields of aliphatic hydrocarbons that possess the characteristics of a blend component of a liquid transportation fuel or other value-added chemical products.
