Abstract:
Disclosed are a catalytic method and system for producing aromatic hydrocarbons from aliphatic hydrocarbons or light naphtha. In an aspect, the process comprises adding a diluent comprising a heavy aromatic hydrocarbon (for example, C 7 -C 9+ ) to a reactor feedstock comprising aliphatic hydrocarbons (for example, C 6 -C 8 ) or light naphtha to form a reactor feed stream, such that the heat capacity of reactor feed stream is higher than the heat capacity of feedstock. The reactor feed stream is heated and contacting with a catalyst under conditions sufficient to aromatize at least a portion of the aliphatic hydrocarbons and form a product stream comprising a primary aromatic hydrocarbon product and a heavy aromatic hydrocarbon product. In an aspect, the diluent can comprise a heavy aromatic hydrocarbon having at least one carbon atom more than the primary aromatic hydrocarbon product.

Claim (Index 35):
A catalytic hydrocarbon reforming system comprising:\n a fractionator having an inlet to receive an initial feedstock comprising naphtha and an outlet to discharge a reactor feedstock comprising aliphatic hydrocarbons; a diluent input line for adding a diluent comprising a heavy aromatic hydrocarbon to the reactor feedstock to form a reactant feed stream having a first temperature; at least one furnace capable of heating the reactant feed stream to a second temperature; at least one reactor charged with a catalyst comprising an inorganic support, a Group 8-10 metal, and at least one halide, the reactor having an inlet to receive the reactant feed stream and an outlet to discharge a reactor effluent stream at a third temperature; and a reactor effluent stream leaving the final reactor comprising a primary aromatic hydrocarbon product and a heavy aromatic hydrocarbon product; a separation system that receives the reactor effluent stream and separately, discharges the primary aromatic hydrocarbon product, the heavy aromatic hydrocarbon product, hydrogen, and a raffinate; a first return line extending from the separation system to the diluent input line for providing the diluent, the diluent comprising at least a portion of the heavy aromatic hydrocarbon product; separating the reactor effluent stream into the primary aromatic hydrocarbon product; the heavy aromatic hydrocarbon product, hydrogen, and a raffinate; forming the diluent from the heavy aromatic hydrocarbon product; and wherein forming the diluent comprises adding the heavy aromatic hydrocarbon having at least one carbon atom more than the primary aromatic hydrocarbon product.
