US Patent:

6750374, Jun 15, 2004
Filed:

Aug 20, 2002
Appl. No.:

10/223980
Inventors:

John Ronald Sanderson - Austin TX
Terry Lee Renken - Austin TX
Michael Wayne McKinney - Cedar Park TX
Assignee:

Huntsman Petrochemical Corporation - Austin TX
International Classification:

C07C 510
US Classification:

585267, 585270
Abstract:

A process for producing cyclohexane by benzene hydrogenation using a hydrogen source that contains impurities, such as carbon monoxide and/or light hydrocarbons, wherein a supported catalyst reduces benzene to cyclohexane and carbon monoxide to methane and water. Alkenes, such as ethylene, are also reduced to their alkane counterparts. Under the disclosed operating conditions, the process proceeds without deactivation of the catalyst, and without the formation of a significant amount of cracking products, such as methylcyclopentane.

Filed:

Apr 18, 2002
Appl. No.:

10/124925
Inventors:

Terry L. Renken - Austin TX, US
Matthew W. Forkner - Austin TX, US
Assignee:

Huntsman Petrochemical Corporation - The Woodlands TX
International Classification:

B01J 23/00
B01J 23/70
B01J 23/72
US Classification:

502317, 502313, 502305, 502319
Abstract:

Provided herein are catalysts useful in reductive amination, which include nickel, copper, zirconium and/or chromium, oxygen, and tin. The presence of the tin increases the selectivity of the catalyst in reductive aminations over the catalysts of the prior art.

US Patent:

7550550, Jun 23, 2009
Filed:

Aug 29, 2003
Appl. No.:

10/524247
Inventors:

Howard P. Klein - Austin TX, US
Bruce L. Burton - Round Rock TX, US
Matthew W. Forkner - Austin TX, US
David C. Alexander - Austin TX, US
Terry L. Renken - Austin TX, US
Chris E. Godinich - Houston TX, US
Assignee:

Huntsman Petrochemical Corporation - The Woodlands TX
International Classification:

C08G 18/32
US Classification:

528 68, 528419, 564508, 564505
Abstract:

Provided herein are polyamine precursors useful in the manufacture of epoxy resins. Use of a polyamine precursor according to the invention provides an epoxy resin formulation having an increased working time over prior art amines used for curing epoxies. Increased working times translate to the ability to manufacture composites which could not be made using conventional epoxy curing agents, such as composite blades for wind-driven turbines. Such polyamines are also useful in polyurea formulations for lengthening reaction time, thus allowing more flow of applied polyurea coatings prior to gellation.
