Abstract:

The present invention is directed to a series of new compounds, combining the unique properties of fullerenes and bio-active amino acid residues, and to methods for making such compounds. The present invention is directed toward fullerene-based amino acids, and to amino acid residues, peptide chains, proteins, and polypeptides made from such fullerene-based amino acids. The present invention is further directed to amino acid residues, peptide chains, proteins, and polypeptides comprising such fullerene-based amino acids and into which such fullerene-based amino acids have been incorporated. Exemplary compounds have been prepared, and these compounds have been characterized and confirmed with infrared (IR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS), etc. These new compounds, which are additions to the existing amino acid residue family, may potentially possess useful pharmaceutical application and may provide a new platform for further exploration in cancer therapy, and peptide and protein engineering.

Additives To Enhance Metal Removal In Refinery Desalting Processes

US Patent:

8372270, Feb 12, 2013
Filed:

Jan 18, 2011
Appl. No.:

13/008667
Inventors:

Tran M. Nguyen - Houston TX, US
Jerry J. Weers - Richmond TX, US
Jianzhong Yang - Missouri City TX, US
Ksenija Babic - Katy TX, US
Assignee:

Baker Hughes Incorporated - Houston TX
International Classification:

C10G 17/04
C10G 33/04
US Classification:

208251R, 208252, 208290, 208291
Abstract:

It has been discovered that metals can be removed or transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition that contains a demulsifier (for instance, an oxyalkylated alkyl resin and/or a crosslinked polypropylene glycol), a surfactant, a diketone and a solvent (for instance an aromatic solvent). The method may also include introducing a hydroxyl carboxylic acid and/or at least one mineral acid to reduce the pH of the desalter wash water. The method permits transfer of metals into the aqueous phase with little or no hydrocarbon phase undercarry into the aqueous phase. The composition is particularly useful in treating crude oil emulsions, and in removing iron therefrom.

US Patent:

8557002, Oct 15, 2013
Filed:

Nov 12, 2010
Appl. No.:

12/944997
Inventors:

Jianzhong Yang - Missouri City TX, US
Paul J. Biggerstaff - Stafford TX, US
Assignee:

Baker Hughes Incorporated - Houston TX
International Classification:

C10L 1/02
C10L 1/19
C10L 1/185
US Classification:

44398, 44447
Abstract:

The reaction product resulting from the chemical reaction of an alkyl phenol with an acid or an anhydride selected from the group consisting of a saturated dicarboxylic acid, an unsaturated dicarboxylic acid, an anhydride of a saturated dicarboxylic acid, an anhydride of an unsaturated dicarboxylic acid, and combinations thereof, has been discovered to improve the properties of various fluids. In a non-limiting example, the reaction products may have an acid number from about 0 to about 50 that may improve the lubricity and/or corrosion of fuels and lubricants, such as hydrocarbon fuels and lubricants, when added thereto.

Additives For Reduction Of Exhaust Emissions From Compression Ignition Engines

US Patent:

20080295395, Dec 4, 2008
Filed:

May 29, 2008
Appl. No.:

12/128918
Inventors:

Bradley G. Harrell - Pearland TX, US
Michael J. Zetlmeisl - Katy TX, US
Christopher Gallagher - Broken Arrow OK, US
Jianzhong Yang - Houston TX, US
Andrew J. McCallum - Katy TX, US
Assignee:

Baker Hughes Incorporated - Houston TX
International Classification:

C10L 1/18
US Classification:

44322
Abstract:

Exhaust emissions resulting from the combustion of hydrocarbon fuels in compression ignition engines may be reduced using a homopolymer that may be polyisobutylene, polypropylene, and/or hyperbranched polyalpha-olefins. Optionally, an alkyl nitrate such as 2-ethylhexylnitrate (2EHN), and/or a peroxide, such as hydrogen peroxide, may also be used together with the homopolymer. Both NOx and particulate matter emissions (PM) may be reduced using ppm quantities of the additive compositions; alternatively, NOx emissions may be lowered or reduced while PM emissions do not substantially increase.

US Patent:

20090255849, Oct 15, 2009
Filed:

Apr 8, 2009
Appl. No.:

12/420605
Inventors:

Jianzhong Yang - Missouri City TX, US
Joseph J. Arensdorf - Oak Ridge North TX, US
Melanie V. Baker - League City TX, US
Assignee:

BAKER HUGHES INCORPORATED - Houston TX
International Classification:

C10L 1/04
C10G 17/02
US Classification:

208 15, 208219, 208 14
Abstract:

Mercaptans and/or hydrogen sulfide (HS) in hydrocarbons, naphthas, gasolines, and the like may be scavenged therefrom by being brought into intimate contact with a mercaptan scavenger formulation containing at least one disubstituted azodicarboxylate of the formula ROOCN═NCOOR, where Rand Rare independently alkyl groups, alkenyl groups and aromatic groups having from 1 to 18 carbon atoms. These scavengers remove mercaptans and/or HS from hydrocarbons faster than many conventional mercaptan scavengers. An effective scavenging amount of disubstituted azodicarboxylate in the hydrocarbon fluid ranges from about 5 to about 20 parts by weight based on 1 part as sulfur of mercaptan and/or HS.
