Integrated Process To Coproduce Aromatic Hydrocarbons And Ethylene And Propylene

US Patent:
8017822, Sep 13, 2011
Filed:
Oct 5, 2009
Appl. No.:
12/573767
Inventors:
Howard Lam Ho Fong - Sugar Land TX, US
Richard Dale Swain - Houston TX, US
Assignee:
Shell Oil Company - Houston TX
International Classification:
C07C 1/26
US Classification:
585408, 585322, 585641, 585642, 568795, 568796, 568797, 568798, 568802
Abstract:
An integrated process for producing aromatic hydrocarbons and ethylene and/or propylene and optionally other lower olefins from low molecular weight hydrocarbons, preferably methane, which comprises: (a) contacting at least one low molecular weight alkane, preferably methane, with a halogen, preferably bromine, under process conditions sufficient to produce a monohaloalkane, preferably monobromomethane, (b) reacting the monohaloalkane in the presence of a coupling catalyst to produce aromatic hydrocarbons and C alkanes, (c) separating the aromatic hydrocarbons from the product mixture of step (b) to produce aromatic hydrocarbons, and (d) cracking at least part of the C alkanes in an alkane cracking system to produce ethylene and/or propylene and optionally other lower olefins.

Integrated Process To Coproduce Aromatic Hydrocarbons And Ethylene And Propylene

US Patent:
2010023, Sep 16, 2010
Filed:
Mar 15, 2010
Appl. No.:
12/724139
Inventors:
Howard Lam Ho FONG - Sugar Land TX, US
Richard Dale Swain - Houston TX, US
International Classification:
C07C 51/255, C07C 2/00, C07C 37/04, C07C 37/02, C07C 37/08, C07C 37/58
US Classification:
562412, 585322, 568795, 568796, 568798, 568802
Abstract:
An integrated process for producing aromatic hydrocarbons and ethylene and/or propylene and optionally other lower olefins from low molecular weight hydrocarbons, preferably methane, which comprises: (a) contacting one or more low molecular weight alkanes, preferably methane, with a halogen, preferably bromine, under process conditions sufficient to produce a monohaloalkane, preferably monobromomethane, (b) reacting a first portion of the monohaloalkane in the presence of a coupling catalyst under process conditions sufficient to produce aromatic hydrocarbons and Calkanes, (c) separating the aromatic hydrocarbons from the product mixture of step (b) to produce aromatic hydrocarbons, (d) reacting a second portion of the monohaloalkane in the presence of a coupling catalyst under process conditions sufficient to produce ethylene and/or propylene.

Process Of Making Ketones

US Patent:
5583263, Dec 10, 1996
Filed:
Aug 30, 1995
Appl. No.:
8/520950
Inventors:
Duraisamy Muthusamy - Houston TX
Chia-Chung Wang - Katy TX
Richard D. Swain - Houston TX
David B. Litzen - Houston TX
William R. Pledger - Pearland TX
Assignee:
Shell Oil Company - Houston TX
International Classification:
C07C 4562
US Classification:
568396
Abstract:
A multistep process for producing amyl ketones is provided. In the process, a methyl ketone is reacted with butyraldehyde to form a C. sub. 7 aldol condensation product which is then dehydrated to form an olefinic ketone and hydrogenated to form an amyl ketone. The process is suitable for coproduction along with the production of MIBK and yields products with a high selectivity.
