Patent number: 11008266Abstract: 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, C7-C9+) to a reactor feedstock comprising aliphatic hydrocarbons (for example, C6-C8) 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.Type: GrantFiled: September 9, 2019Date of Patent: May 18, 2021Assignee: Chevron Phillips Chemical Company LPInventor: Eric P. Weber

Patent number: 9938206Abstract: A process for aromatizing hydrocarbons comprises: converting at least a portion of highly branched hydrocarbons in a feed stream into selectively convertible components, and aromatizing the selectively convertible components to produce an aromatization reactor effluent. The aromatization reactor effluent comprises an aromatic product. Converting at least the portion of the highly branched hydrocarbons into the selectively convertible components may include contacting the feed stream with an isomerization catalyst in an isomerization reaction system under isomerization reaction conditions; and isomerizing the portion of the highly branched hydrocarbons in the feed stream into the selectively convertible components.Type: GrantFiled: October 5, 2017Date of Patent: April 10, 2018Assignee: Chevron Phillips Chemical Company LPInventors: Eric P. Weber, Tin-Tack Peter Cheung, Yu Su

Patent number: 6790342Abstract: 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 C3− stream and a C3+ stream; hydrogenating the C2− stream in a hydrogenation zone to remove a portion of the acetylene to produce the dilute ethylene stream and routing the C3+ stream to storage or other process unit. Another process comprises separating a cracked gas stream in a depropanizer zone to form a C3− stream and a C4+ stream; separating the C3− stream in a deethanizer zone to form a C2− and a C3 stream; hydrogenating a portion of the acetylene in the C2− stream in a hydrogenation zone to produce a dilute ethylene stream; and routing the C3 stream to storage or other process unit.Type: GrantFiled: February 27, 2002Date of Patent: September 14, 2004Assignee: Chevron Phillips Chemical Company LPInventors: Rodney L.

Patent number: 6004452Abstract: 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.Type: GrantFiled: November 14, 1997Date of Patent: December 21, 1999Assignee: Chevron Chemical Company LLCInventors: Gary A Ash, Nhu Q Dao, Arnold J Gloyn, N J Haritatos, Paul I Hodgen, Stuart R MacPherson, Scott Gordon Morrison, Gerald J Nacamuli, Paul M Spindler, Bruce J Thom, Eric P Weber, Richard Wolpert
