US Patent:

7582272, Sep 1, 2009
Filed:

Mar 12, 2004
Appl. No.:

10/799987
Inventors:

David J. Glova - Kingwood TX, US
Dan B. Knorr - Humble TX, US
Assignee:

Chevron Phillips Chemical Company LP - The Woodlands TX
International Classification:

B01D 53/72
US Classification:

4232453, 502 52
Abstract:

A method of servicing a catalytic reactor system, comprising an abatement of at least one hazardous substance from the catalytic reactor system while preserving activity of a catalyst contained therein. A method of servicing a catalytic reactor system, comprising oxidizing the catalytic reactor system at a temperature of from about 350 F. to about 500 F. to abate at least one hazardous substance from the catalytic reactor system and reducing servicing time by about 50% of a time required for complete regenerative oxidation of the catalytic reactor system. A method of servicing a catalytic reactor system, comprising abating at least one hazardous substance from the catalytic reactor system such that a fouling rate of a catalyst contained therein is substantially the same before and after the servicing.

US Patent:

7932425, Apr 26, 2011
Filed:

Jul 20, 2007
Appl. No.:

11/780693
Inventors:

Christopher D. Blessing - Jubail Industrial, SA
Scott H. Brown - Kingwood TX, US
David J. Glova - Lyman SC, US
Daniel M. Hasenberg - Kingwood TX, US
Dennis L. Holtermann - Kingwood TX, US
Gyanesh P. Khare - Kingwood TX, US
Assignee:

Chevron Phillips Chemical Company LP - The Woodlands TX
International Classification:

C07C 2/52
C10G 35/06
US Classification:

585419, 585418, 208138, 208139
Abstract:

A hydrocarbon aromatization process comprising adding a nitrogenate, an oxygenate, or both to a hydrocarbon stream to produce an enhanced hydrocarbon stream, and contacting the enhanced hydrocarbon stream with an aromatization catalyst, thereby producing an aromatization reactor effluent comprising aromatic hydrocarbons, wherein the catalyst comprises a non-acidic zeolite support, a group VIII metal, and one or more halides. Also disclosed is a hydrocarbon aromatization process comprising monitoring the presence of an oxygenate, a nitrogenate, or both in an aromatization reactor, monitoring at least one process parameter that indicates the activity of the aromatization catalyst, modifying the amount of the oxygenate, the nitrogenate, or both in the aromatization reactor, thereby affecting the parameter.
