Filed:

Nov 16, 2001

Appl. No.:

09/992445

Inventors:

Rodney L. Porter - Pearland TX
Anne M. Balinsky - Kingwood TX
Eric P. Weber - Kingwood TX

Assignee:

Chevron Phillips Chemical Company, L.P. - The Woodlands TX

International Classification:

C10G 6900

US Classification:

208 49, 208211, 585318, 585319, 585329, 585362

Abstract:

A process is provided to produce a dilute ethylene stream and a dilute propylene stream to be used as feedstocks for producing olefin-based derivatives. Specifically, the dilute ethylene stream is used as a feedstock to produce ethylbenzene, and the dilute propylene stream is used as a feedstock to produce cumene, acrylic acid, propylene oxide and other propylene based derivatives.

US Classification:

208 49, 208211, 585318, 585319, 585329, 585362

Abstract:

Processes are provided to produce a dilute ethylene stream and a dilute propylene stream from a cracked gas stream. One process comprises separating the cracked gas stream to produce a C stream and a C stream; hydrogenating the C stream in a hydrogenation zone to remove a portion of the acetylene to produce the dilute ethylene stream and routing the C stream to storage or other process unit. Another process comprises separating a cracked gas stream in a depropanizer zone to form a C stream and a C stream; separating the C stream in a deethanizer zone to form a C and a C stream; hydrogenating a portion of the acetylene in the C stream in a hydrogenation zone to produce a dilute ethylene stream; and routing the C stream to storage or other process unit.

International Classification:

C10G 5106

US Classification:

208 80

Abstract:

A process is provided for producing high purity benzene and high purity paraxylene from a hydrocarbon feed. In one aspect, the process comprises: (a) reforming a hydrocarbon feed using either a monofunctional catalyst or a bifunctional catalyst to provide one or more reformate streams; (b) fractionating the reformate stream to provide a toluene stream, a benzene stream, and a xylene stream; (c) subjecting the toluene stream to disproportionation; (d) purifying the benzene stream by extraction followed by distillation to provide a high purity benzene product; and (e) purifying the xylene stream by simulated moving bed countercurrent adsorption followed by crystallization to provide a high purity paraxylene product.

Appl. No.:

16/564314

Inventors:

- The Woodlands TX, US
Eric P. Weber - Kingwood TX, US

Assignee:

Chevron Phillips Chemical Company LP - The Woodlands TX

International Classification:

C07C 5/41
C07C 5/31
B01J 19/24

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-C) to a reactor feedstock comprising aliphatic hydrocarbons (for example, C-C) 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.
